An oxide-based flexible electrochromic transistor under mechanical stress

Today mechanical flexibility has become an important feature for electronic devices, especially in flat display panels. Here we demonstrate the device operation of a tungsten oxide-based flexible electrochromic transistor (ECT), which was fabricated on 0.1 mm thick polyethylene terephthalate film. The ECT can be operated by applying voltage of ±3 V for 1 s when the radius of curvature was larger than 16 mm, indicating that the flexible ECT exhibited a strong resistance to static strains. However, the resistance of the channel increased by fatigues from applying cyclic flexural strains. Present flexible ECT would highly be useful for the economically viable curved display panels. However, its vulnerability to fatigue needs improvements for other applications.

Refrigeration and modified atmosphere to the conservation of ‘Malasia’ Star fruit

ABSTRACT: Despite the fact that cold storage and modified atmosphere techniques have already been studied for fresh cut Star fruit, little has been done considering the whole fruit. Besides that, each cultivar has its peculiarities, so the efficiency of combined postharvest treatments should be studied. The objective of this study was to evaluate the effect of polyvinyl chloride (PVC), 8.5 µm thick and low-density polyethylene (LDPE), 33 µm thick associated with cold storage (10 ± 1 °C and 5 ± 1 °C / 85 ± 5% RH) on the conservation of ‘Malasia’ Star fruit. Storage at 25 oC maintained Star fruit overall quality, regardless of the film type, up to four days. The weight loss was higher in fruit packed with PVC, but this fact was not noticed by the sensory analysis. The storage in 5 and 10 oC did not caused chilling injury but fruit presented retention of yellow color development and firmness reduction; these aspects were positively assessed by the sensory analysis. The film type did not influence the conservation of the fruit. The storage at 5 and 10 °C, regardless of the package film, prolonged ‘Malasia’ star fruit shelf life up to 16 days, followed by two days at 25 °C.

Assessment of phthalate migration in polyethylene food contact materials sold on the Ghanaian market

Chemical contaminants that migrate into food may affect the safety and quality of the food depending on the nature and composition of the packaging material. The introduction of different packaging materials and designs have increased the specific hazards that humans are exposed to due to chemical migration into food. In Ghana, these food contact materials are not only used for food storage or transportation but also, foods such as kenkey are cooked with these food contact materials at very high temperatures for longer periods hence increasing the possibility of the migration rate and thereby posing hazard to consumers. The purpose of this study is to assess the quality and safety of polyethylene food contact materials used in the Ghanaian food industry in terms of phthalate migration. Five different polyethylene food contact materials specifically black polyethylene bags (BPB), plain polyethylene bags (TAB), thick plain polyethylene films/bags (TPB), polyethylene food containers (PFC) and polyethylene plastic bottles (PPB) were purchased from three different markets namely; Madina, Makola and Kwame Nkrumah circle within the Accra Metropolitan Assembly. The samples were analysed using a GC-MS after extraction with aqueous and fatty foods simulants.

Suppression of Antenna Backscatter on a Nanosat Using a Resistively Loaded FSS Absorber

A very thin microwave absorber that can be integrated into the outermost layer of thermal blankets is proposed as a means to electromagnetically decouple payload antennas from spacecraft platforms. The effectiveness of this concept is evaluated for a critical test case where a linearly polarized dipole antenna working at 10 GHz is placed at three different distances above the surface of a $\text{10 cm}$ Nanosat mock-up. This scenario is chosen as the dipole will radiate into both half spaces and any reflections from the vehicle onto which it is mounted will significantly affect its behavior. A resistively loaded frequency selective surface (FSS) absorber is employed to supress the energy contained in the antenna backlobes, and it is shown that the installed performance for all three geometries closely resembles the beam shape of the antenna in isolation. Experimental results have been obtained for one arrangement to confirm that the directive gain is increased by 18 dB in the boresight direction. The FSS absorber is composed of an array of resistively loaded hexagonal patches that are patterned on a 1.12 mm ( $\lambda /25$ ) thick foil-backed polyethylene terephthalate sheet to replicate the physical construction of commercially available space blankets.

Enhancement of THz resonance using a multilayer slab waveguide for a guided-mode resonance filter.

We propose a multilayer slab waveguide (SWG) to enhance the resonance of the transmittance with a guided-mode resonance (GMR) filter. The resonance characteristics of the GMR filter were studied in three types according to the method of attaching the grating film to a SWG, which consists of 25 µm thick polyethylene terephthalate (PET) film layers separated by 25 µm air layers. The resonance depth with the multilayer SWG was improved over that of the monolayer SWG because the refractive index and absorption of the multilayer SWG were reduced. However, because resonance with a high Q-factor in the monolayer SWG has a large attenuation loss due to material absorption, the resonance enhancement was insufficient even for the multilayer SWG. We were able to make the resonance depth up to 5.2 times larger than the monolayer SWG in the TE1,1 mode using a five-layer SWG. We verified the enhancements with the multilayer SWG using a finite-difference frequency-domain (FDFD) simulation.

Blood metal levels, leucocyte profiles, and cytokine profiles in patients with a modular dual-mobility hip prosthesis: early results from a prospective cohort study.

The aim of this study was to evaluate blood metal ion levels, leucocyte profiles, and serum cytokines in patients with a total hip arthroplasty (THA) involving modular dual-mobility components. A total of 39 patients were recruited, with clinical follow-up of up to two years. Outcome was assessed using the Harris Hip Score (HHS, the 12-Item Short-Form Health Survey (SF-12), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and a visual analogue scale (VAS) for pain. Blood concentrations of cobalt (Co), chromium (Cr), and serum cytokines were measured. Subpopulations of leucocytes were analyzed by flow cytometry. The clinical performance was good. Blood Co levels (ref 1.0 µg/l) were mildly elevated in seven patients at three months, and two patients at two years' follow-up. The preoperative Cr levels were normal except for one patient with a detectable Cr (1.2 µg/l). Cr levels were detectable in three patients at three months, two patients at one year, and three patients at two years' follow-up. No patients had symptoms suggestive of failure. Although flow cytometry showed constant circulating leucocyte profiles, there was a significant reduction of serum interleukin (IL)-4, IL-5, and interferon gamma (IFNγ) postoperatively compared with the preoperative levels (p < 0.05). These results suggest that THA using modular dual-mobility components is safe. This allows an opportunity to use a large femoral head and a thick polyethylene bearing surface, which is especially useful in revision procedures or high-risk situations when added stability is required.

InflateSail de-orbit flight demonstration results and follow-on drag-sail applications

The InflateSail (QB50-UK06) CubeSat, designed and built at the Surrey Space Centre (SSC) for the Von Karman Institute (VKI), Belgium, was one of the technology demonstrators for the European Commission's QB50 programme. The 3.2 kg 3U CubeSat was equipped with a 1 m long inflatable mast and a 10 m2 deployable drag sail. InflateSail's primary mission was to demonstrate the effectiveness of using a drag sail in Low Earth Orbit (LEO) to dramatically increase the rate at which satellites lose altitude and re-enter the Earth's atmosphere and it was one of 31 satellites that were launched simultaneously on the PSLV (polar satellite launch vehicle) C-38 from Sriharikota, India on 23rd June 2017 into a 505 km, 97.44° Sun-synchronous orbit.Shortly after safe deployment in orbit, InflateSail automatically activated its payload. Firstly, it inflated its metre-long metal-polymer laminate tubular mast, and then activated a stepper motor to extend four lightweight bi-stable rigid composite (BRC) booms from the end of the mast, so as to draw out the 3.1 m × 3.1 m square, 12 μm thick polyethylene naphthalate (PEN) drag-sail. As intended, the satellite immediately began to lose altitude, causing it to re-enter the atmosphere just 72 days later – thus successfully demonstrating for the first time the de-orbiting of a spacecraft using European inflatable and drag-sail technologies.The InflateSail project was funded by two European Commission Framework Program Seven (FP7) projects: DEPLOYTECH and QB50. DEPLOYTECH had eight European partners including DLR, Airbus France, RolaTube, Cambridge University, and was assisted by NASA Marshall Space Flight Centre. DEPLOYTECH's objectives were to advance the technological capabilities of three different space deployable technologies by qualifying their concepts for space use. QB50 was a programme, led by VKI, for launching a network of 50 CubeSats built mainly by university teams all over the world to perform first-class science in the largely unexplored lower thermosphere.The mast/drag-sail technology developed by SSC will next be used on a third FP7 Project: RemoveDebris, launched in 2018, which will demonstrate the capturing and de-orbiting of artificial space debris targets using a net and harpoon system. This paper describes the results of the InflateSail mission, including the observed effects of atmospheric density and solar activity on its trajectory and body dynamics. It also describes the application of the technology to RemoveDebris and its potential as a commercial de-orbiting add-on package for future space missions.

Exposure response function for a quantitative prediction of weathering caused aging of polyethylene

Abstract The exposure response function of the carbonyl formation over the bulk has been determined for a high-density polyethylene of a thickness of 200 μm, which was used as a weathering reference material according to ISO TR 19032. To this end, spectral sensitivity was studied by local measurement of the effect of spectrally dispersed irradiation. Both the exposure device and the methodology of determination are described. The temperature dependency of photooxidation was determined by UV exposure at various temperatures between 23 and 80 °C. Deviations from linearity and thus reciprocity below 40 °C are discussed and assumed to be related to diffusion limitations. An Arrhenius approach – based on data of linear carbonyl formation – has been incorporated into the exposure response function. Using this exposure response function, aging in terms of the distribution of a quantitative property change over a plastic component can be predicted for a specific outdoor location with real chronologic weather data as input for the exposure. Thus, artificial and natural weathering can be linked and compared. The established exposure response function has been validated by outdoor exposure results from the literature. If an estimated diffusion limitation is taken into consideration, calculations and published data are in good agreement.

Plasma-assisted growth of polyethylene fractal nano-islands on polyethylene oxide films: Impact of film confinement and glassy dynamics on fractal morphologies

Abstract Plasma-assisted vapor-phase deposition of (–CH2–)100 macromolecules is performed onto the surface of pre-deposited polyethylene oxide (PEO). It leads to the formation of two-dimensional 7 nm thick polyethylene (PE) islands of the ramified fractal or ordered dendrite shape. AFM-infrared nanospectroscopy confirms the phase separation whereas complementary specific heat nanocalorimetry indicates that the crossover from one island shape to another is related to glassy dynamics in underlying PEO. Segmental dynamics is found to be controlled by the thickness of PEO and it manifests in the development of star-shaped PE dendrites on ultrathin (

CYSP-BEAM: A multi-detector directional spectrometer for in-beam neutron spectrometry

CYSP-BEAM is a directional neutron spectrometer formed by a thick polyethylene cylindrical collimator followed by a sensitive capsule that contains several active thermal neutron detectors located at different depths along the cylindrical axis. Due to a thick lateral shield made of polyethylene and borated rubber, only neutrons from the direction identified by the collimating aperture can reach the internal detectors. As the response function of the internal detectors tend to peak at increasing energies as the detector depth increases, the device has spectrometric properties. This type of moderated spectrometer, whose prototype was the CYSP (CYlindrical SPectrometer), is capable to combine the functionalities of Bonner Spheres in a single device, thus requiring only one exposure to measure all the energy components of the incident beam, from thermal up to GeV neutrons. The neutron spectrum is obtained via few-channel unfolding methods. With respect to the original CYSP, the new CYSP-BEAM device is optimized to operate in the direct intense beam of neutron producing installations, such as large scale neutron science facilities. Compared with CYSP, CYSP-BEAM has narrower collimating aperture and the internal detectors have sensibility a factor 100 lower. Its response matrix was simulated using MCNPX. This paper describes the new device focusing on the internal detectors, the response matrix and the test measurement performed using the 14 MeV beam produced at the ENEA Frascati Neutron Generator (FNG).

Laser Direct Writing of Heteroatom (N and S)-Doped Graphene from a Polybenzimidazole Ink Donor on Polyethylene Terephthalate Polymer and Glass Substrates.

In this paper, for the first time, a laser direct writing technique is reported to form S- and N-doped graphene patterns on thin (0.3 mm thickness) polyethylene terephthalate (PET) and glass substrates from a specially formulated organic polybenzimidazole (PBI) ink, without thermally affecting the substrates and without the need for a metallic precursor. Unlike standard graphene ink printing, postcuring at high temperatures is not needed here, thus avoiding potential substrate distortion and damages. A UV laser beam of 355 nm wavelength is used to generate photochemical reactions to break the CS bond (2.8 eV) from dimethyl sulfoxide (DMSO, a component of the PBI ink) and the CN bond (3.14 eV) of PBI and form N- and S-doped graphene on the substrates. The sheet resistance of the laser-induced graphene is as low as 12 Ω sq-1 on PET, matching that of indium-tin oxide (ITO). The laser-written doped graphene shows hydrophilic characteristics, unlike pristine graphene. The S- and N-doped graphene allows the tailoring of bandgaps and thus controlling electrical and chemical properties. The optical transparency of the written graphene is below 10% which could be improved in the future. Potential applications include printing of flexible circuits and sensors, and smart wearables.

Initial operation results of NE213 scintillation detector for time-resolved measurements on triton burnup in KSTAR.

In time-resolved measurement for triton burnup in Korea Superconducting Tokamak Advanced Research (KSTAR) deuterium plasmas, an NE213 liquid scintillation detector was installed and operated during the 2017 KSTAR campaign. The detector is composed of an NE213 scintillator (50 mm in diameter and 10 mm in thickness) and a photomultiplier tube (PMT). The PMT anode signal was processed under a data acquisition system which contains a field programmable gate array circuit and pulse processing software that is capable of discriminating gamma-ray and neutron pulse signals. In order to determine an appropriate threshold level for the 14 MeV neutron signal resulting from triton burnup, the NE213 scintillation detector was calibrated by using d-d and d-t neutron generators at the National Fusion Research Institute and Intense 14 MeV Neutron Source Facility, OKTAVIAN, Osaka University, Japan. The detector was installed on KSTAR with a 10 mm thick soft-iron stray magnetic field shield and a radiation shield which consists of 100 mm thick lead blocks and 200 mm thick borated polyethylene blocks. A discrimination range for d-t neutron was determined based on test results from neutron generators and KSTAR. Data points selected from the discrimination range were consistent with the classical triton confinement characteristics. In conclusion, under condition of an input counting rate of 1.9 × 105 counts per second (CPS), the detector is able to measure triton burnup signals up to 500 CPS for various plasma parameters.

Radiotranslucent foam isolation blocks improve regional tissue accuracy in whole body DXA scans

Introduction DXA regional body composition accuracy and precision are critically important in many clinical applications including monitoring lymphedema, performance training, and injury recovery. While total body composition measurements are highly precise, regional measurements exhibit lower precision partly due to inconsistencies in subject positioning. In particular, tissue overlap between body regions (such as breast tissue from the trunk overlying the arms, or hands overlapping the hip) limits the ability to follow regional changes in fat and lean masses, as well as symmetry measures. We propose a modified DXA scan protocol that includes radiolucent isolation blocks to perfect positioning and regional accuracy. Objective To develop a protocol for whole body DXA scanning that optimizes the trueness and precision of arm, trunk, and leg regions by preventing tissue overlap. Methods Four candidate materials were evaluated for X-ray measured density, stiffness, and cost. Sheets of the selected material were cut and tapered into wedges to fit between the arms and trunk, and between the legs. A pilot recruitment of 15 healthy adults underwent whole body DXA scans on a Hologic Discovery/W. Density of each material was assessed by scanning with the Hologic Whole Body Phantom. Each participant had 2 scans with the foam positioners (with repositioning), and 1 without. All scans were analyzed by a single ISCD-certified technologist. Custom subregions were defined to isolate the arms from the trunk during analysis. Differences in regional masses with and without the foam positioners were calculated. Results Of the four materials tested, 1”-thick closed-cell polyethylene foam sheet was optimal due to low cost ( Conclusions Polyethylene foam positioning blocks can be used to ensure clear, repeatable delineation of soft tissue between anatomical regions. This technique may improve DXA regional body composition accuracy and precision, improving the ability of DXA to monitor changes in individual limb masses.

Effect of neutron and -ray on charge-coupled device for vacuum/extreme ultraviolet spectroscopy in deuterium discharges of large helical device.

A charge-coupled device (CCD) is widely used as a detector of vacuum spectrometers in fusion devices. Recently, a deuterium plasma experiment has been initiated in a Large Helical Device (LHD). Totally 3.7 × 1018 neutrons have been yielded with energies of 2.45 MeV (D-D) and 14.1 MeV (D-T) during the deuterium experiment over four months. Meanwhile, γ-rays are radiated from plasma facing components and laboratory structural materials in a wide energy range, i.e., 0.01-12.0 MeV, through the neutron capture. It is well known that these neutrons and γ-rays bring serious problems to the CCD system. Then, several CCDs of vacuum ultraviolet/extreme ultraviolet/X-ray spectrometers installed at different locations on LHD for measurements of spectra and spatial profiles of impurity emission lines are examined to study the effect of neutrons and γ-rays. An additional CCD placed in a special shielding box made of 10 cm thick polyethylene contained 10% boron and 1.5 cm thick lead is also used for the detailed analysis. As a result, it is found that the CCD has no damage in the present neutron yield of LHD, while the background noise integrated for all pixels of CCD largely increases, i.e., 1-3 × 108 counts/s. The data analysis of CCD in the shielding box shows that the background noise caused by the γ-ray is smaller than that caused by the neutron, i.e., 41% from γ-rays and 59% from neutrons. It is also found that the noise can be partly removed by an accumulation of CCD frames or software programming.

Wearable detector device utilizing microstructured semiconductor neutron detector technology

A Wearable Detector Device (WDD) has been outfitted with Microstructured Semiconductor Neutron Detectors (MSNDs) to aid in the search and localization of special nuclear materials (SNMs). Many SNMs decay by spontaneous fission and emit free neutrons. The WDD detects these neutrons and stores interaction rate information to alert the operator to the presence of special nuclear material. The WDD is composed of 16 Modular Neutron Detectors (MNDs), each populated with a 4 × 6 array of 1-cm2 active area, 500-μm thick MSNDs. The individual MSNDs each have an intrinsic thermal-neutron detection efficiency of approximately 30%. Each MND connects to a communications dongle, and the MND and dongle were encased in a 3-in. wide by 5-in. tall by 0.6-in. thick high-density polyethylene moderator (HDPE) case. The 16 MNDs, connected to Controller Area Network dongles, communicate with a master control board, which also contains the battery bank and power conditioning electronics. The operational lifetime of the battery-powered WDD is greater than 12 h per single charge. The WDD, mounted on an ANSI 42.53 phantom, reported 8.12 ± 0.07 cps and 12.93 ± 0.07 cps for a bare and moderated 21.9-ng 252Cf source at a distance of 1 m, respectively. The background count rate was 0.446 ± 0.002 cps. The gamma-ray rejection ratio of the WDD for 137Cs measured at a dose rate of 10 mR/h was 1.8 × 10−8.

Similar Outcome, but Different Surgical Requirement in Conversion Total Knee Arthroplasty following High Tibial Osteotomy and Unicompartmental Knee Arthroplasty: A Meta-Analysis.

The present systematic review and meta-analysis were conducted to find out how effective any subsequent conversion total knee arthroplasty (TKA) would be after unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) and which is better in outcomes. A rigorous and systematic approach was used. Each of the selected studies was evaluated for methodological quality. Data were extracted by the following standardized protocol: study design, level of evidence, cases enrolled, age, sex ratio, follow-up, kind of index surgery, type of index surgery, average time to failure, mode of failure, surgical data, preclinical score, post-clinical score, and major related complications. Nineteen articles were included in the final analysis. In conversion TKA following UKA, revision components (metal augment, bone graft, and stem) were frequently used, and thicker polyethylene was used comparing to the primary TKA. In the conversion TKA following HTO, only stem was more common (relative risk of revision component UKA:HTO = 0.57:0.07). The estimated range of motions (ROM) of conversion TKA following HTO and UKA was 107.75° (101.93-113.58°) and 111.84° (108.41-115.26°), respectively (p > 0.05). The knee scores of conversion TKA following HTO and UKA were 89.10 (86.45, 91.75) and 85.48 (79.82, 91.14), respectively (p > 0.05). The function scores were 78.60 (72.44, 84.76) and 75.60 (69.85, 81.35), respectively (p > 0.05). Clinical outcome was similar between conversion TKA following HTO and UKA. However, conversion TKA after UKA required more revision components and thicker polyethylene, while conversion TKA after HTO sometimes required a stem to bypass the osteotomy gap.

Laser piloted ignition of electrical wire in microgravity

This work studied the piloted ignition of electrical wires in both normal gravity and microgravity using the laser-induced spark. Unique experiments were conducted in the microgravity parabolic flight with laboratory wires under the oxygen concentration of 14–21% and external radiation of up to 15.9 kW/m2. The wire sample consists of a 2.5-mm thick core, using the solid copper (Cu) or the hollow stainless steel (SS) tube, and a 0.75-mm thick black polyethylene (PE) insulation. This is the first piloted-ignition experiment on solid fuel in microgravity with the laser-induced spark as the pilot. Experimental results show that regardless of the oxygen level, the ignition delay time is always smaller in microgravity than in normal gravity, indicating a higher fire risk in the microgravity space environment. As the heat flux and the oxygen concentration increase, auto-ignition is observed. Moreover, if the core is exposed to the external heating source, it can heat the insulation to promote the ignition, different from the heat sink found in past ignition research. This unique research provides valuable information about the fire risk of electrical wire in microgravity and future long-term space travel.

∆E/∆E Measurements of Energetic Ions Using CVD Diamond Detectors

Experimental and computational results of a ΔE/ΔE diamond detection system are presented. The ΔE/ΔE detection system was evaluated using energetic proton and iron beams striking thick polyethylene targets at the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL). The measured data for diamond sensor A show good agreement with the Geant4 simulation. In addition, simulations have demonstrated the ability to identify hydrogen isotopes using a diamond detection system.

Effect of packaging on the shelf life of tender palmyra (Borassus flabellifer) fruit endosperm

Tender palmyra (Borassus flabellifer) fruit endosperm, also known as ice apple is consumed during the summer months especially in Southern and Eastern India. The endosperm is manually removed from the tender palmyra fruit using a heavy knife or sickle by the road side vendors before it is consumed. An investigation on retail film packaging was conducted to study the shelf life of tender palmyra endosperm in sealed packages. The research was carried out to study the effect of packaging films of different thickness on the physio-sensory properties of the endosperm under ambient (32±2°C) and refrigerated (5 ±1°C) conditions. The endosperm was packed in polypropylene bags of 40 and 80 micron thickness and low density polyethylene bags of 150 and 450 micron thickness and High Molecular density (HM) polyethylene bags of 40 micron thickness. The packed samples were kept for storage under ambient and refrigerated conditions. They were evaluated for the changes in weight loss, TSS and also firmness, colour and odour by subjective evaluation at periodic interval during storage. The weight loss was minimum for the sample packed in 450 micron Low Density Polyethylene bag under refrigerated storage. Sensory scores revealed that the overall acceptability(5.0) of palmyra endosperm packed in 450 micron thickness Low Density Poly Ethylene was highest at the end of storage under ambient condition. Similarly, highest overall acceptability (4.0) was observed in High Molecular density polyethylene bag of 40 micron thickness at refrigerated storage. Under normal conditions, palmyra endosperm is prone to spoilage within few hours due to oxidation and fermentation. The results of the study revealed that the shelf life of palmyra endosperm could be extended up to two days under ambient condition, when packed in Low Density Poly Ethylene bag of 450 micron thickness, whereas under refrigerated condition, shelf life could be up to eight days, when packed in high molecular density polyethylene bags of 40 micron thickness.

A radiopaque 3D printed, anthropomorphic phantom for simulation of CT-guided procedures.

To develop an anthropomorphic phantom closely mimicking patient anatomy and to evaluate the phantom for the simulation of computed tomography (CT)-guided procedures. Patient CT images were printed with aqueous potassium iodide solution (1 g/mL) on paper. The printed paper sheets were stacked in alternation with 1-mm thick polyethylene foam layers, cut to the patient shape and glued together to create an anthropomorphic abdomen phantom. Ten interventional radiologists performed periradicular infiltration on the phantom and rated the phantom procedure regarding different aspects of suitability for simulating CT-guided procedures. Radiopaque printing in combination with polyethylene foam layers achieved a phantom with detailed patient anatomy that allowed needle placement. CT-guided periradicular infiltration on the phantom was rated highly realistic for simulation of anatomy, needle navigation and overall course of the procedure. Haptics were rated as intermediately realistic. Participants strongly agreed that the phantom was suitable for training and learning purposes. A radiopaque 3D printed, anthropomorphic phantom provides a realistic platform for the simulation of CT-guided procedures. Future work will focus on application for training and procedure optimisation. • Radiopaque 3D printing combined with polyethylene foam achieves patient phantoms for CT-guided procedures. • Radiopaque 3D printed, anthropomorphic phantoms allow realistic simulation of CT-guided procedures. • Realistic visual guidance is a key aspect in simulation of CT-guided procedures. • Three-dimensional printed phantoms provide a platform for training and optimisation of CT-guided procedures.
