Abstract

Results of tomographic volume visualization depend on a large number of acquisition and processing parameters. In this study, localization accuracy of isosurfaces is investigated, using simulated and phantom data. Guidelines for choosing parameters are given, and a pictorial index of typical effects resulting from various parameter settings is presented. Provided that a suitable threshold value is used, it is shown that the accuracy is almost one order of magnitude better than the scanner resolution.
