Abstract

This paper presents an efficient volume measurement method for quantitative assessments within a virtual liver surgery planning system. The measurement is carried out by hardware-accelerated voxelization of surface-based models in order to be applicable for interactive applications. The focus of this paper is the presentation of our voxelization technique suitable for off-the-shelf PC graphics cards including two different data retrieval approaches. Moreover, the measurement can be performed off-screen while not disturbing the rest of the application. Another important issue discussed in this paper is the applicability study within the planning system. Our measurement toolkit has been applied on several medical objects and delivers interactive response times.
