Internet Protocol (IP) based networks are increasingly being used as alternatives to the traditional circuit-switched networks for carrying voice traffic. IP telephony is taking a firm hold in the world telecommunication market for a wide range of applications including telemedicine. The merits of IP telephony for telemedicine lie in cost-savings and new(More)
Physician often infers the patient's heart problem by listening to heartbeat sound. Such technique is well known as auscultation. The doctor's auscultation skill was gain after he or she experiencing a lot of cases of heart diseases and heartbeat sounds. There is a need of computer-aided equipment to analyze heartbeat sound especially for young doctors to(More)
We report here on a study of creating medical an image library comprised of simple but digitized gastrointestinal video-scope images, which were digitally compressed using MPEG-1 compression, and on the use of this library for clinical and educational applications. We have designed and installed a test-bed database (WWW) for gastrointestinal video-scope(More)
Telemedicine is valuable to many developing countries. International use of telemedicine is widespread. Telemedicine can improve health care in the developing countries by removing time and distance barrier, and optimize the use of limited health services in developing countries. The purpose of this paper is to investigate the current situation of(More)
In this article, the authors report the methods for obtaining subsidies for overseas telemedicine projects from Japanese sources based on their own personal experiences. The Japanese Government is already subsidizing such specialized NGOs (Non-Governmental Organizations) as the Telemedicine Society of Japan and Basic Human Needs and, Japanese trading(More)
Tokai University School of Medicine provided a short-term e-Health training program for persons from Pacific Island Nations from 2006 until 2008 supported by funds from the Sasakawa Peace Foundation. There were lectures on software, hardware and topics relating to e-Health. We could assess the current medical situation in the Pacific Islands through this(More)
We have conducted tests utilizing super high-definition CRTs (hereafter, referred to as a “super high-definition image system,” or “SHD”: 2048 × 2048 pixels, 24-bit RGB gradation, noninterlace system) for autonomous and distributed medical image database systems. The system is capable of providing six times the image definition of a hi-vision television(More)
Independent component analysis (ICA) is a multivariate data analysis tool. The basic principle of ICA is the assumption of independency of the source data. On the separation of the data source, ICA algorithm searches for a demixing matrix that will maximize the independency. This searching process is mostly done in iterative way and involving high order(More)
At present, mobile phones are not a useful tool for medical control during a disaster. We have estimated the number of satellite channels that would be needed for telemedicine in a major disaster using the Erlang B equation. This indicated that 29 satellite channels would be sufficient for the operation of a telemedicine system for hospital-to-hospital(More)
