Auto-stereoscopic Display and Manipulation of 3D Medical Images

Roger Hubbold

(University of Manchester)

Direct volume rendering (DVR), by ray casting, has a number of advantages for visualizing data sets where structure boundaries are fuzzy, or where structures are nested - a common occurrence in medical images captured by scanners. However, DVR also poses some problems which must be solved if it is to find wide acceptance. First, fast but accurate algorithms are needed if interaction is required. Second, ways of presenting the resulting images unambiguously are called for, so that structures and depth relationships can be correctly perceived. Third, we need techniques for interaction with the 3D images.

In this talk I will outline how we are trying to solve these problems by integrating a parallel compute-server, network protocols to access the server from low-cost workstations, and novel auto-stereoscopic display techniques for presenting and interacting with the resulting images. I will discuss the application of these methods to the complex and safety-critical procedure of radiation therapy planning.
