Pelaksanaan Quality Control Pesawat Sinar X di Pelayanan Radiodiagnostik

Background: Quality Control can be used as a monitoring of the reliability of X-Ray Unit during the validity period of the Conformity Test Certificate. During the use of X-ray Unit, there is the potential for damage to components during the validity period of the certificate of passing the Compliance Test. If the X-Ray Unit Reliability Test is only carried out during the Compliance Test, then if there is a decrease in the quality and safety of the X-ray Unit it cannot be immediately known. This has the potential to endanger patients, radiation workers and the public. In Banyumas Regency, there are 80 Radiation Source Utilization Permits spread across 34 radiodiagnostic installation. Preliminary studies show that not all radiodiagnostic installation carry out routine X-ray machine reliability tests according to the Keputusan Menteri Kesehatan Republik Indonesia Nomor 1250/Menkes/SK/XII/2009 Tentang Pedoman Kendali Mutu (Quality Control) Peralatan Radiodiagnostik.
 Method: This research type is qualitative with survey of 20 radiodiagnostic installation using a questionnaire instrument. Quality control conducted periodically includes kVp accuracy test, linearity and reproducibility mA, exposure time accuracy test, tube leak test, collimator beam suitability test, collimator shutter efficiency test, collimator light strength test, HVL measurement, implementation of reject analysis program and availability and qualifications of quality control officers and availability of quality control equipment. Then the data will be grouped based on research objectives and presented descriptively.
 Result: From the results of data collection, 1 hospital did not have a quality control officer and 4 hospitals had a quality control officer with an educational background of Diploma IV in Radiology Engineering without any Radiology Equipment Quality Control training. Meanwhile, 15 hospitals have quality control officers with an educational background in the Medical Physics Undergraduate Program and have attended training in Quality Control of Radiology Equipment. Of the 20 hospital radiology installations, there were 7 hospitals that did not carry out the Reject Analysis Program. This was done with the assumption that Digital Radiography had been used in both the CR and DR modalities. A number of 13 hospitals continued to carry out the Reject Analysis Program even though they had used Digital Radiography. Of the 20 hospital radiology installations, there are 6 hospitals that independently carry out X-ray unit testing within the framework of a quality control program. However, only 1 hospital conducts regular testing. Testing is also limited to the accuracy of the collimator field and the strong light of the collimator. Fourteen hospitals did not carry out a quality control program independently but only carried out an X-ray unit calibration test once a year which was carried out by BPFK and an X-ray unit distributor company.
 Conclusion: The implementation of quality control of x-ray machines on a regular basis has not been carried out by all radiodiagnostic services, even though they already have quality control officers. One of the reasons is the availability of quality control equipment needed for testing and supervision of radiodiagnostic service management. The role of management of radiodiagnostic services is needed to overcome these problems.

The Teknik Pemeriksaan Dacryocystography Dengan Klinis Obstruksi Ductus Nasolacrimal

Background: One examination using contrast media that is rarely encountered is the Dacryocystography examination. At one type A hospital in Jakarta only 34 examinations were carried out in 2019, while at another type A hospital this examination was not carried out at all. Dacryocystography examination is a radiological examination of the nasolacrimal system by filling the luminal canal with radiopaque contrast. This examination will not be visible well without using contrast. Based on the experience that the author found during practice at one of the type A hospitals in Jakarta, the Dacryocystography examination with clinical Nasolacrimal Ductus Obstruction only uses 1 (one) projection, namely AP (Anteroposterior). In contrast, according to Ballinger (2011), this examination uses 3 (three) projections—namely PA Caldwell, PA Waters, and Lateral.
 Methods: This research is descriptive and qualitative in nature, namely by conducting observations, interviews, and documentation at the KIARA radiology installation, RSUPN Dr. Cipto Mangunkusumo. With 1 (one) sample, interviews with 3 (three) radiographers and 3 (three) radiology specialists. Dacryocystography technique: the patient without preparation is then taken on a plain AP photo, then contrast media is injected into the lacrimal punctum of both eyes of the patient and a post-contrast photo with AP projection. Then the patient's eyes are dripped with NaCl to reduce the concentration of the contrast medium.
 Results: The results of the study showed that the Nasolacrimal Ductus was blocked because the contrast medium stopped at the location of the nasolacrimal duct blockage.
 Conclusions: In the Dacryocystography examination with clinical Nasolacrimal Ductus Obstruction, contrast media is injected using a special syringe that has been modified in the form of a bent and blunt needle. For projections, only 1 projection is used, namely Antero Posterior (AP) for preliminary photos and post-contrast photos which will depict the image of the Nasolacrimal Ductus having obstruction or blockage.

Technical Error Factors On Panoramic Radiographic Examination At The Radiology Installation Of Unjani Dental and Mouth Hospital

Panoramic is a three-dimensional curved zone where anatomical structures are well defined on panoramic radiography. Panoramic radiography includes a detailed anatomy of the jaw complex with some superimpositions and distortions that can be exacerbated by technical errors in image acquisition as well as many extra-jaw anatomical structures that are able to give clear description to interpretate. Therefore, in obtaining a panoramic radiograph it is necessary to obtain the desired structure with high quality and minimal distortion. Errors that often occur in producing good panoramic radiographs are technical errors or when positioning the patient and during the panoramic examination. The purpose of this study was to determine the main factors causing the errors so that technician can produce good quality radiographs, take into account patient placement at the time of examination, perform film processing, and handle general film procedures. The research method used was a quantitative method with a descriptive observational approach. The number of samples was 64 radiographs, which are adult patients over 18 years old with the use of exposure factors in the range of 60kV, 10mA and 16.4s. All radiographs were taken by qualified radiographers with more than 5 years of experience. The radiographs were viewed and observed without any modification on a computed radiography monitor screen. Radiographic results will be evaluated by experienced technician who have worked more than 5 years. Evaluation is obtained by analyzing the data descriptively in the form of assessment of the percentage of rejection of panoramic radiographs to make conclusions. Out of the 2418 panoramic radiographs viewed, 2354 (97%) radiographs had no errors while 64 (3%) radiographs showed one or more positioning error. The most common positioning error observed in the radiographs was failuer to position chin tipped high (56,02%). Whereas the least common error recorded were movement and apron shadow (1.15%).

Determination of the Diagnostic Reference Level (DRL) in Samarinda Hospitals

The diagnostic reference level (DRL) is a form of investigative level used as a tool to help optimize protection to radiation exposure for diagnostic and interventional procedures. The purpose of this study was to determine the local DRL values for the examination of the abdomen, thorax, and head at radiology installations. The modality used was 128-slice CT scan. The numbers of patients whose data were used were 200 for abdominal examinations, 160 for thoracic examinations, and 100 for head examinations. Overall, the total patient whose data was used was 460. Data processing in this study was carried out with a quantitative analysis technique, namely descriptive statistics. This analysis technique used secondary data obtained from the results of recaptures or archival books for examination of the abdomen, thorax, and head. Data processing was carried out with a measure of diversity through the calculation of the third quartile in the data distribution. It was assumed that 75 % of patients performed examinations with a common diagnosis. The results of these calculations are visualized in the form of graphs of the relationship of computed tomography dose index volume (CTDIvol) with the number of patients and a graph of the relationship of dose length product (DLP) with the number of patients. In the abdominal examination, a CTDIvol of 12 mGy and a DLP of 1545.5 mGy·cm. In the thoracic examination, a CTDIvol of 11 mGy and a DLP of 903 mGy·cm were obtained. For the head examination, a CTDIvol of 34.25mGy and a DLP of 2190.25 mGy·cm were obtained.

The Effect of Orientation on Increasing Knowledge and Reducing Anxiety During MRI Examination in a Radiology Installation

Radiology services encompass the use of ionizing and non-ionizing radiation sources for diagnostic imaging and therapy. Magnetic Resonance Imaging (MRI) is a crucial clinical radiology service, primarily conducted in hospital-based healthcare facilities. The aim of this research is to assess the influence of patient orientation on MRI-related knowledge and anxiety. This study employs a quasi-experimental design with pretest and posttest measurements, taking into account variables such as age, gender, education, diagnosis, and experience. The results of the research indicate that patient orientation effectively reduces anxiety levels and has a positive impact on the patient's experience during MRI examinations. The conclusions that can be drawn from this research are: The influence of orientation on knowledge in groups that were not given orientation and orientation found that there was no significant difference in the average knowledge before and after orientation (p>0.05), this was because respondents had previously read first about MRI examinations on the internet and after reading the knowledge questionnaire their knowledge increased because after they filled out the questionnaire they asked the researchers what was stated in the knowledge questionnaire. The research suggests that the use of open MRI machines with wider bore diameters, along with patient-oriented practices such as allowing patients to see during the examination, can reduce anxiety.

OPTIMISASI PROTEKSI DAN KESELAMATAN RADIASI TERHADAP PAPARAN MEDIK PADA FOTO RONTGEN DADA MENGGUNAKAN PENGATURAN FAKTOR EKSPOSI

Chest X-ray examination is a type of examination that is often carried out in radiology installations. Every patient who undergoes a chest X-ray examination will receive radiation exposure. The amount of chest X-ray radiation exposure depends on the exposure factors that currently refer to the manufacturer's recommendations. So, it is necessary to optimize radiation protection, which aims to reduce the radiation dose without lowering the quality of the resulting images. One way to do this is by adjusting the exposure factor while maintaining optimal image quality. The method reduces the voltage from 100 kV to 95 kV with a fixed mAs. This method was applied to a total of 100 chest X-ray patients. Each PA position has 50 patients, and AP has 50 patients. Calculations are carried out using the radiation output equation to determine changes in the patient's radiation dose. Next, qualitative and quantitative analysis was carried out to determine changes in the quality of chest X-rays before and after reducing the tube voltage and qualitatively based on a questionnaire assessment by a radiologist while quantitatively based on statistical tests of Exposure Index (S) and Lattitude (L) values on Fujifilm digital radiography. The results show that reducing the voltage can reduce the Entrance Surface Air Kerma (ESAK) from 0.2578 mGy to 0.2295 mGy. In other words, there was a reduction in the radiation dose for chest X-ray patients by 0.0283 or around 11%. Qualitatively, the image results still meet the criteria for chest image acceptance. Likewise, quantitatively, data was obtained that the S and L values of chest X-rays before and after reducing the voltage were not significantly different. The independent data difference test value is 0.598 for the PA projection and 0.809 for the AP projection with α = 0.05. The results of this study indicate that optimization of radiation protection and safety against medical exposure on chest X-rays using exposure settings can be applied by reducing the voltage (kV). Keywords: tube voltage, chest X-ray, X-ray, radiation dose, image quality, radiation protection.
