This paper describes a computerized simulation system for less invasive vascular interventions using virtual-reality (VR)-based technology. A virtual human patient is constructed on top of the visible human data (VHD) incorporating in various vascular disease cases. Specially, the human vascular network is modeled for the use of catheterization simulation.(More)
In this paper, we describe a parametric eyeball modeling system for real-time simulation of eye surgery. A knowledge-based approach is used to parametrically model the ophthalmologic structures. Together with the parametric eye modeling and the integration of patient-specific disease images, the ophthalmologic knowledge databases of eye diseases, eye(More)
The growth of the Internet is making searching tools necessary for computer users. Conventional approaches, like search engines and hierarchical indices, require considerable amount of human efforts to keep up with the Web. It's very time consuming to get facts about something specific, for example, the projects related to mobile agent in the universities(More)
