  • Matti Haveri : We use Voxtool 1.0.4 in a Sparcstation (64MB of RAM) connected via Ethernet to General Electric's High Speed Advantage and GE Sytec CAT-scanners. Segmentation is done through lower and higher HU-thresholds. Shaded surface display, MIP, RaySum, Integral and Multiplanar reformatting (MPR) as well as movie loop (if memory permits full 360 degree rotation with 6 degree intervals is sometimes possible). Select/remove object, filter floaters (user-definable size), scalpel (user-definable cut depth), erosion, dilation, open bridges and close gaps-functions. Intersection, union, difference and delta-functions between manipulated models. Seems to be quite stable - I've crashed it only a few times. Restarting the program or rebooting clears occasional memory-problems. Can save only two models at a time and the program sometimes loses link to the original slices which is _very_ annoying. 3D-images can be saved as individual still-images to disk in GE's image-format (hope we will be able to open and view this format in the other platforms as well). In the current version area-measurements require at least two contiguos slices which is also annoying. If the 3D-model has to use more than 60 512x512 image's space as virtual memory the program is too slow to use interactively.
