Medical Image Sharing Research Articles

Medical Image Sharing in Japan.

This paper reports the history, background including politics, current status of Japan’s health imaging study and other information sharing. Its realization was slow until the Ministry of Health, Labour and Welfare (MHLW) started paying digital image storage at the same rate as films in 2008. Information sharing was initiated in early 2010s, which was before vendors became ready for Integrating the Healthcare Enterprise (IHE) cross-enterprise document sharing (XDS), with the result that most of 34 large regional sharing systems are in non-standardized protocol. One standardized example is the Hamamatsu area where inexpensive online PDI (portable data for imaging) was introduced.

Hamming Code Strategy for Medical Image Sharing

In medical practice, the scanned image of the patient between the patient and the doctor is confidential. If info is stored on a single server and the server is successfully attacked, it is possible to expose confidential information. Password encryption and data authentication are commonly used to protect patient data, however, encryption and data authentication are computationally expensive and take time to execute on a mobile device. In addition, it is not easy for the patient details related to medical images to leak if the hacked image are not visual.Therefore, in this paper, we propose a way to make medical images remain untouched in this sense. We use our method to quickly create two shadows from two medical images and store them on two servers. Revealing a shadow image does nothing to compromise the confidentiality of a patient’s health. This method is based on Hamming code. With low computational cost, the proposed scheme is suitable for tablet, pamphlets and other mobile devices.

Medical Image Sharing with Portable Devices

Background: In this presentation, we look at available solutions for medical services on portable devices and the benefits and features that are available on these devices today. Objectives: 1. Electronic devices for medical image viewing 2. Portability advantages for image sharing 3. Image viewing features available on portable devices Outline: Medical imaging has been evolved with the advent of electronic and digital technologies over the past decade. While films and printers were used to transmit images in the past, the use of PACS systems has been spread over the past decade and medical images have been viewed and browsed in digital devices. Nowadays, digital devices are a wide range of mobile devices -Handheld- to large devices and Wide Screens -which are daily demanded by users and professions for viewing and browsing medical images. Digital access to most up-to-date versions of patient medical images, medical reports, and disease history can accelerate the development of treatment, reduce the likelihood of medical and prescription errors, and prevent additional testing. Furthermore, digital access can save time and money for both patients and healthcare centers. On the other hand, the rapid expanding of services in imaging and medical image sharing is one of the challenges of ensuring the accuracy and integration of information and work processes in the way that professions always have access to accurate online data of patients. This data integration, in particular, should be done between PACS, RIS/HIS systems, and imaging systems to circulate data automatically as much as possible without the need for manual data entry. To achieve this critical capability, other systems have been developed in the DICOM standard to serve as interfaces between the above elements, enabling the process of automating data transfer and integration. In the remainder of this presentation, the existing solution for the realization of a digital hospital and its capability in diagnosing and working with portable devices is outlined.

Towards an Information Infrastructure for Medical Image Sharing.

Information infrastructures involve the notion of a shared, open infrastructure, constituting a space where people, organizations, and technical components associate to develop an activity. The current infrastructure for medical image sharing, based on PACS/DICOM technologies, does not constitute an information infrastructure since it is limited in its ability to share in a scalable, comprehensive, and secure manner. This paper proposes the DICOMFlow, a decentralized, distributed infrastructure model that aims to foment the formation of an information infrastructure in order to share medical images and teleradiology. As an installed base, it uses the PACS/DICOM infrastructure of radiology departments and the internet e-mail infrastructure. Experiments performed in real and simulated environments have indicated the feasibility of the proposed infrastructure to foment the formation of an information infrastructure for medical image sharing and teleradiology.

Efficient Quantum Information Hiding for Remote Medical Image Sharing

Information hiding aims to embed secret data into the multimedia, such as image, audio, video, and text. In this paper, two new quantum information hiding approaches are put forward. A quantum steganography approach is proposed to hide a quantum secret image into a quantum cover image. The quantum secret image is encrypted first using a controlled-NOT gate to demonstrate the security of the embedded data. The encrypted secret image is embedded into the quantum cover image using the two most and least significant qubits. In addition, a quantum image watermarking approach is presented to hide a quantum watermark gray image into a quantum carrier image. The quantum watermark image, which is scrambled by utilizing Arnold’s cat map, is then embedded into the quantum carrier image using the two least and most significant qubits. Only the watermarked image and the key are sufficient to extract the embedded quantum watermark image. The proposed novelty has been illustrated using a scenario of sharing medical imagery between two remote hospitals. The simulation and analysis demonstrate that the two newly proposed approaches have excellent visual quality and high embedding capacity and security.

Ethics of Smartphone Usage for Medical Image Sharing

Technology advances in medicine have led to increased usage of smartphones and applications in facilitating provision of care. As the increased power of technology paves the way for advances, it is fundamental that ethical considerations are comprehensively explored. This paper explores the importance of consent, confidentiality, and data security in use of smartphone applications for transferring medical information.

SmartWADO: an Extensible WADO Middleware for Regional Medical Image Sharing.

Medical image sharing is an important problem in modern radiology, with wide applications in Internet and mobile devices. Some important features need to be added and optimized to medical image sharing. In this paper, we present an extensible Web Access to DICOM Persistent Objects (WADO) middleware based on image cache and real-time Web monitor technology for regional medical image sharing. We first develop the extension method of WADO standard and workflow of extended WADO service. Then, we design a medical image cache method to improve the performance of medical image on-demand transmission. Using the real-time monitor can discover the performance bottlenecks and optimized critical points. The experimental results show that the middleware effectively delivers medical images and reports to Web clients over the Internet, regardless of the platform used for access. It can be deployed in one hospital to provide WADO service to medical workers and also can be applied to regional picture archiving and communication systems (PACS) to transmit medical images and reports to Internet users in a way that is transparent to end-user applications.

Secret Medical Image Sharing and EPR Data Embedding Scheme over Cloud Computing Environment

The fast development in the term of telecommunication helps on the appearance of variety of modern applications such as the telemedicine where the patients' digital data can transfer over insecure mediums between the doctors for farther diagnosis and dealing with these transmitted data. Therefore, the protection of the exchanged medical data is essential especially when working on the cloud computing environment, where the security is considered a major issue. In addition to the security, the high visibility of the medical images must also be achieved. This paper presents a novel approach that guarantees the secure sharing of medical images over the cloud computing environment by providing the mean of trust management between the authorized parities of these data and also allows the privacy sharing of the Electronic Patients' Records (EPR) string data between those parities while preserving the shared medical image from the distortion. The experimental results show the efficiency of the proposed scheme and also the robustness against various types of attacks.
