Paper Abstract

Three dimensional medical scanners are widely available in today's hospitals to acquire a dataset of the human body without the need for surgery. The usefulness of this diagnostic information is limited by the lack of techniques to visualize the datasets. With the increasing computer power of today's workstations it is possible to make a transparent view of the 3D dataset. An interactive mode is necessary, however, to fully explore the 3D dataset. If both a high resolution and a high interactive speed is required, the necessary computational power is enormous. Therefore it is necessary to map the algorithms for volume visualization in a rather specific way onto (dedicated) chips to overcome the performance gap. This paper discusses a high-performance special-purpose low-power system, the Real-Time Volume Rendering Engine (RT-VRE), capable of rendering a 3D dataset of 2563 voxels onto a display of 7502 pixels with an interaction rate of 25 images per second. The RT-VRE allows biomedical engineers to interactively visualize and investigate their data.
