Abstract

We present a prototype system for computer assisted stereotactic neurosurgery. It is especially suited to integrate vascular data with the stereotactic trajectory and with other information obtained from different imaging modalities. Patient image data from CT, MRI and DSA are acquired using a patient-fixed stereotactic frame with additional external markers for image registration. After preprocessing, all data are available for stereotactic planning and confirmation of electrode positioning. Interactive 3D devices simulate the electrode trajectory, which is projected on a stereoscopic set of angiograms. Alternatively, cross-sections of this trajectory with each of the CT or MR slices can be calculated at the same time. Additional features such as reslicing of the original CT or MR slices along the probe trajectory, are being implemented. All software is written on a 3D graphics workstation. In addition, we use a stereoscopic imaging system employing electro-optical shuttering glasses, and a 3D cursor in stylus form for the simulation of the electrode trajectory.
