Telemedicine system using computed tomography van of high-speed telecommunication vehicle.

The current medical system provides medical services to patients who visit hospitals. However, medical services can be provided at or close to the home of the patient using fully equipped mobile telemedicine systems. Such a system can identify the disease at an early stage, improve quality of life and prognosis through early diagnosis and treatment, and reduce the costs of medical service. Furthermore, the unit can provide mass screenings of the population, as well as full medical service to remote areas. The Telecommunications Advanced Organization of Japan, Matsumoto, Japan, and Shinshu University Hospital, Matsumoto, Japan, established a research center for a unique telemedicine project using a mobile system. The mobile unit consists of a van that houses a spiral computed-tomography (CT) machine and various telecommunications equipment. The unit allows medical examination, CT scanning, and on-line two-way transfer of image data/teleconferencing to a medical center for consultation with various specialists. We have used the system thus far for the early detection of lung cancer through mass screenings over a four-year period in 29 administrative districts. Mass screenings of 19117 residents resulted in the identification of 75 cases of early lung cancer who were later treated by partial pneumonectomy at Shinshu University Hospital and affiliated hospitals. We have also used the system to provide medical services to rural areas, as telemedicine support at remote areas, wintertime telemedicine support to an international sports competition, and various medical services to a home-care facility.
