This research aims at developing fast parallel slice cutting and partial exposing algorithms used in real-time 3D-texture-based volume rendering for image-guided surgery and therapy planning. In texture-based volume rendering, a large amount of slices are needed to render the volume to achieve high quality image, but for real-time interactive volume rendering, the computation time is critical. Abstract: We describe a parallel volume-rendering algorithm, which consists of two parts: parallel ray tracing and parallel compositing. In the most recent implementation on Connection Machine's CM-5 and networked workstations, the parallel volume renderer evenly Cited by: Handbook of Robotic and Image-Guided Surgery provides state-of-the-art systems and methods for robotic and computer-assisted surgeries.

  Today, parallel hardware is routinely used in graphics workstations, and numerous software-based rendering systems have been developed for general-purpose parallel architectures. This article provides an overview of the parallel rendering field, . Volume rendering. Volume rendering is a technique for directly displaying a sampled 3D scalar field without first fitting geometric primitives to the samples. We are working on developing efficient and accurate algorithms for displaying this sort of data. The traditional slice-based 3D texture volume rendering is performed by slicing the volume in backto-front or front-to-back order with planes oriented parallel to the view plane [18]. Each. Parallel rendering (or distributed rendering) is the application of parallel programming to the computational domain of computer graphics. Rendering graphics can require massive computational resources for complex scenes that arise in scientific visualization, medical visualization, CAD applications, and virtual research has also suggested that parallel rendering can be .

VL3, a scalable, parallel graphics processing unit–based volume-rendering software library. VL3 accepts CT data sets from any medical scanner without specialized protocols or preprocessing. For this application, VL3 loads CT data sets and outputs two 3D volumes that represent the left and right eye virtual perspectives and whose interocular offset simulates binocular stereovision. Book • Browse book content This chapter explores various options of indirect volume rendering. In addition to the various plane-oriented displays such as orthogonal, oblique, and curved reformatted slice displays, the chapter focuses on a surface-based display of the structures of interest. comprising an image-guided surgery. volume rendering. Wu et al. [WAR] present fast parallel slice cutting and partial exposing algorithms which are used for real-time volume rendering to support image-guided surgery and therapy planning.
