Valuable lessons learned from the R&D work on the Cholocestectomy trainer are beeing transferred now into the development of the Virtual Endoscopic Surgery Trainer for Gynaecology

The MIS-Trainer is described more detailed here.
You can find even more photographs of the MIS-Trainer here.
Model of Human Anatomy (639x511 gif, 190k)
Such models are used as a basis for the surgery trainer. The organs are modelled as B-Spline surfaces (modelled by DSL/Rottendburg, FRG) using the SOFTIMAGE software. The models are then converted to KISMET NURBS geometry.
Converted CT dataset of human skull (1278x1022 jpg, 133k)
Another model generation approach is the conversion of CT-, MRI-, MRA-datasets from voxel-volumes to polygonal surfaces. The skull was generated using Marching-Cubes segmentation (Lorensen et.al.). This works well for bone anatomy.
Realtime Volume Rendering
Another approach to visualize volume datasets in realtime is to use hardware supported volume rendering techniques without preliminary conversion into polyhedral surface models. The methods we use and recent results are explained in more detail on this page.

The KISMET image shows an "outside" view of the surgery trainer scenario with simulated camera view (upper left viewport). KISMET allows as well for model based camera tracking. The camera viewing area is displayed as a pyramidal shape.
