ABSTRACT: In this paper we describe the extension of a parallel, distributed, direct volume renderer for use with a novel auto-stereoscopic display. We begin by briefly describing the target application of our research, radiation therapy planning, why we believe that stereoscopic viewing may be helpful for this, and the design of our DVR system. We then report on some of the problems we have encountered, and the results we have obtained in experiments. These demonstrate that stereoscopic viewing is beneficial for perceiving depth in transparent DVR images. We illustrate the application of the system to the visualisation of prostate cancer treatment plans. Finally, we describe the use of head-tracking to implement 3D stereo look-around. Keywords: auto-stereoscopic display, volume rendering, visualisation, medical imaging, radiotherapy. 1 Introduction For several years, direct volume rendering (DVR) by ray casting has been investigated as a tool for visualisation in medicine [11]. Here,...

ABSTRACT: this paper, however, we focus on the difficulties of visualising 3D volume data, and we report the results of preliminary experiments designed to evaluate the utility of stereoscopic displays for this purpose. The remainder of the paper is organised as follows. In the next section we outline the specific problem we are trying to solve: the interactive visualisation and manipulation of radiation therapy plans. We introduce, briefly, direct volume rendering methods outlining the approach we have taken and the reasons for this. Next, we address some of the problems which arise, and how stereoscopic displays may help to alleviate these. We then describe our experiments and their results, concluding with a discussion of their significance. 2. Radiation therapy planning
