ABSTRACT

Accurate and rapid differential diagnosis are required for personalized cancer treatment. However, owing to the numerous molecular tests used for establishing a diagnosis, pathologists need time to investigate and confirm necessary test items. We present a guideline-based decision support system for effective workflow with regards to the molecular tests for pathological differential diagnosis.

ABSTRACT

Real-time video pictures can be transmitted inexpensively via a broadband connection using the DVTS (digital video transport system). However, the degradation of video pictures transmitted by DVTS has not been sufficiently evaluated. We examined the application of DVTS to remote consultation by using images of laparoscopic and endoscopic surgeries. A subjective assessment by the double stimulus continuous quality scale (DSCQS) method of the transmitted video pictures was carried out by eight doctors. Three of the four video recordings were assessed as being transmitted with no degradation in quality. None of the doctors noticed any degradation in the images due to encryption by the VPN (virtual private network) system. We also used an automatic picture quality assessment system to make an objective assessment of the same images. The objective DSCQS values were similar to the subjective ones. We conclude that although the quality of video pictures transmitted by the DVTS was slightly reduced, they were useful for clinical purposes. Encryption with a VPN did not degrade image quality.

ABSTRACT

We developed a secure medical image transmission system by using TCP2 which is a new technology that establishes secure communications in transport layer. Two experiments were conducted; TCP2 performance tests, and field tests that transmit real-time digital video image in domestic and international settings by equipping TCP2 with DVTS (Digital Video Transmission System). The results showed DVTS equipped with TCP2 has enough performance to send secure and high quality medical images. It was considered that medical network using TCP2 would contribute as an essential technology to telemedicine.

ABSTRACT

If the quality and efficiency of medical services are to be ensured, electronic health records (EHR) and EHR-supporting infrastructure must be prevalent. Many hospitals, however, have EHR systems for their internal use only, and the standardization process for the exchange of medical information is still in process. This standardization process addresses information security and is considering public key infrastructure (PKI) as one security measure, but PKI is rarely used by medical practioners because of its poor user-friendliness. Here we propose an effective use of the identity-based encryption (IBE) system as a security measure. This system enables us to send encrypted and signed messages without requiring the receiver to get a public key, and it enables us to deliver secured messages to ambiguous receivers like those to whom letters of reference are sent. We evaluated the feasibility of this technology by using the analytic hierarchy process, which is an effective analysis tool when selection and judgment depend on nonquantitative psychological factors, to analyze the results of an experiment in which medical workers used E-mail agents with and without PKI and IBE. We found that medical practioners and researchers avoid using PKI because of its poor user-friendliness and instead use IBE even though it is harder to install. We therefore think IBE would encourage medical institutions to share patient records.
