Web-based digital medical images

Our Web-based interactive system provides efficient and flexible digital medical image data access and manipulation over the Internet, thus offering potential cost savings to the health care system. It has the potential to integrate and associate data from multiple vendors' systems and multiple imaging modalities, not only at an institutional level but also at a regional level. An example of its potential applications is the expert evaluation of images acquired at remote sites in rural areas, which often lack local specialist services.     

Training in medical informatics

A course is described for the training of medical students in medical informatics (other terms: computational medicine, medical computing). The philosophy behind the course is that there are several modes or levels of human interaction in working with computers, running from registrative functions to assistance at diagnosis and therapy. The course, which consists of five full days, contains lessons in the areas of medical data bases, hospital information systems, medical records, biological signal analysis, computer-assisted diagnosis making, and patient simulation by CAI. Each group of two students has a terminal available, connected to a mini- and/or a microcomputer. The microprocessor takes care of signal analysis and the minicomputer is available for data base construction and interactive operations. The article describes the purposes and contents of all different lessons of this course.

A brief analysis of the economic potentialities of robotics in medicine is also provided     

AIDA and medical courseware

For more than a decade the Department of Medical Informatics has offered one-week training courses on the subject of computer applications in medicine and health care. Since 1983 two courses are given at a rate of one course every two weeks. One course is on programming and problem solving and consists of three modules of increasing complexity in techniques and methods in programming and structured system development. This course focusses on only some aspects of medical informatics: the development of a medical information system, and the problems occurring in the process of automation. These aspects, however, are dealt with in detail. To this end the students are trained in using the programming system MUMPS and the fourth-generation software package AIDA. The second, introductory course is an intensive training on several distinct areas of man-machine interactions. It contains lessons in the fields of communication and recording; storage and retrieval and databases; computation and automation; recognition and diagnosis; and therapy and control. This paper describes the use of AIDA in developing and maintaining lessons for the latter course, and the assistance of AIDA for teaching purposes in the former course.     

Haptics for medical applications

Robots and intelligent machines in the future should adapt themselves autonomously to the open environment in order to realize physical support for human activities. In addition, the physical support by them must be based on the individual’s “action” and “sensation” in order that the physical support becomes really human-friendly. Then, the robots must actively recognize the unknown environment according to the individual’s action. They also have to transmit the environmental information obtained to the individual in harmony with their sensations. Since haptic information is so important, as well as visual information and auditory information, the development of realworld haptics is one of the important key issues for the purpose. Haptic information is inherently bilateral, since an action is always accompanied by a reaction. That means that bilateral control with high transparency is necessary to transmit real-world haptic information artificially. A acceleration-based bilateral controller is one of the solutions for realizing high transparency. There remain many issues to solve for the application of haptics to the physical support of actual human activities. A haptic system with high transparency should obtain flexibility in order to extend its function. This article presents flexible actuation techniques that have high force transferability and flexibility in actuators’ arrangements. Furthermore, in order to support human activities in remote environments, bilateral telehaptics over a network is also described. Finally, this article introduces the fundamental techniques in haptics, including several examples of medical applications, since they are the first target of real-world haptics. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008     

A cyber medical center

This paper describes the design and implementation of a Cyber Medical Center (CMC) using web technology. The intention is to overcome the inefficiency of the traditional filing system for patients' medical records, which are considered to be time and space consuming. Another objective is to enhance the interaction between the user - the patient in this case - and the medical center personnel - the doctors and staff. This task is achieved by developing a cyber medical center interfaced with the Internet to provide direct public access. The traditional filing system is replaced by a database system for maintaining the electronic medical records of all patients in the medical center. The doctors or staff can either view the medical records or update them through the Intranet/Internet. This system has been successfully developed, implemented and tested on the Intranet platform. It will be available in a university medical center for practical use.     

Cyber patients surfing the medical web: Computer-mediated medical knowledge and perceived benefits

Information and communication technologies have introduced new and impressive tools for information sharing and building computer-mediated knowledge repositories in a global context. Clinicians and researchers pay particular attention to technology as a promising tool to empower patients through self-health care management skills and to improve health care communication with providers. This represents a significant step in modern medicine of computer-integrated patient self-health care. This paper aims to examine perceived informational and decisional benefits of computer-mediated health and medical information, more specifically of cancer web-sites, and presents the results of two separate statistical models of perceived benefits. Multivariate hierarchical regression analyses showed that the frequency and time spent visiting medical web-sites are significant predictors of perceived benefits of computer-mediated knowledge. The results also indicated that computer-mediated medical information empowers health consumers to make informed decisions for their health care. The discussion section of the paper contextualizes the findings within the current sociomedical trends of self-health care and partnership with health providers. It is important to understand the perceived benefits of using computer-mediated medical knowledge, so that information and communication technologies can be targeted to educate patients to make informed decisions and to develop patient self-health-care management competencies.     

Using Web resources to construct multilingual medical thesaurus for cross-language medical information retrieval

Due to the language barrier, non-English users are unable to retrieve the most updated medical information from the U.S. authoritative medical websites, such as PubMed and MedlinePlus. However, currently, there is no any cross-language medical information retrieval (CLMIR) system that can help Chinese-speaking consumers cross the language barrier in finding useful English medical information. A few CLMIR systems utilize MeSH (Medical Subject Headings) to help overcome the language barrier. Unfortunately, the traditional Chinese version of MeSH is currently unavailable.In this paper, we employ a semi-automatic term translation method to construct a Chinese–English MeSH by exploiting abundant multilingual Web resources, including Web anchor texts and search–result pages. Through this method, we have developed a Chinese–English Mesh Compilation System to assist knowledge engineers in compiling a Chinese–English medical thesaurus with more than 19,000 entries. Furthermore, this thesaurus has been used to develop a prototypical system for cross-language medical information retrieval, MMODE, which can help consumers retrieve top-quality English medical information using Chinese terms.
