Paper Abstract

This paper describes how a rudimentary type of ray tracing has been implemented on standard CT scanning systems for routine clinical operation. In addition, an image coherence technique is described that speeds rendering of a series of 3-D views of complex anatomic structures. Object surface information from an existing view is used to help predict where ray tracing can begin to search for ray object intersections in the subsequent view. This method is shown to reduce the computational expense of finding ray-object intersections by beginning this search in the proximity of object surfaces. Our goal is to improve 3-D realism and, when clinically appropriate, make the application of 3-D presentations routine.
