VISTAnet, an experimental gigabit network test bed, ties together a CRAY Y-MP™, the Pixel-Planes 5 graphics engine, and an SGI™ host machine to create a metacomputer capable of real-time radiation therapy dose calculation and display. We report on the methods used to manipulate and examine the 3D radiation dose distribution, with emphasis on the visualization, which uses a parallel, interactive, multimodal renderer implemented on Pixel-Planes 5. The real-time display is designed to facilitate comprehension of spatial relationships among the geometrically complex anatomy and radiation dose structures that characterize a 3D radiation treatment scenario. The currently ongoing clinical evaluation of VISTAnet has already yielded encouraging results.

“…Ray casting is an image-order algorithm in which volume data is traversed and sampled by rays emanating from the viewpoint; the rays intersect the image plane; they accumulate (integrate) information about the volume data during traversal. The algorithms and principles used as the basis for VOL2 are outlined in [2,4,5,8,10,13,19]. An early experimental precursor of VOL2 was mentioned in [12,19].…”

This paper describes VOL2, an interactive general-purpose volume renderer based on ray casting and implemented on Pixel-Planes 5, a distributed-memory, message-passing multicomputer. VOL2 is a pipelined renderer using image-space task parallelism and object-space data partitioning. We describe the parallelization and load balancing techniques used in order to achieve interactive response and near-real-time frame rates. We also present a number of applications for our system and derive some general conclusions about operation of image-order rendering algorithms on message-passing multicomputers.

“…Also direct visualization techniques by themselves do not address the issue of relevant anatomy. When attempting to visualize anatomy that is occluded or enclosed in other structures, direct visualization techniques must be combined with other segmentation techniques that incorporate regions of interest [2].…”
