Research On Inter-Active Telemedicine System And Its Key Techniques

Telemedicine is an achievement which combines the network and medical techniques. It realizes sharing of medical information and solves the problems residing in diagnosis and treatment caused by the restriction of regions. The development of telemedicine makes the fast, economic examination, control, diagnosis and medical record management possible. The broad application cases are promising. Telemedicine contains telecommunication technology, information technology and health care technology, extends transaction pattern in classical Hospital Information System HIS and Radiological Information System, RIS , and creates a synthetic hospital information system faced on medical service, imaging and information management.With the improvement on hardware facilities, computer application level and principal of software architecture, telemedicine has become a real thing which is related closely with people's life rather than original principal model in lab paper. At the same time, the principals in telemedicine are changing as new requirement and new application comes out, such as wireless medical service, virtual hospital et al. It is sure that telemedicine will be one of the developing trends of hospital information, but some critical techniques in telemedicine, such as the medical image lossless compression, image transmission, high-resolution display and system developing mode are still need to be improved. As we can see, although there are some implements of those techniques and each has its own characteristics, an unified standards and the state of art are not given. The situation gives us chance to bring new ideas creatively. In this paper, we will redesign telemedicine system with consideration of software engineering and use a different development mode from typical system.The paper discusses a multi-tier telemedicine system-MedJ, and gives a pure Java implement. The architecture is flexible and compatible with different platforms. Within this framework, the paper also discusses image compression techniques mainly focus on JPEG2000, its principle and implement, introduces medical image processing technique with Java based implement and gives some demo results, designs auto-archiving of medical image and data middleware. Forthe new WAP application, the paper lists related techniques and implements a demo model using our architecture. The experimental result has testified the feasibility of our scheme.
