Extension Description

Slicetracker is a 3D Slicer extension for tracking prostate motion during MR-guided prostate biopsies. It implements registration of the pre-procedural to intra-procedural images, which aims to improve reliability of biopsy target re-identification.

Furthermore, a so called z-Frame registration module is included for correlating the patient and 3D Slicers coordinate system. For guidance of the needle a template grid with 15x14 holes is placed in front of the z-Frame. The optimal hole is computed for inserting the needle and obtaining the tissue sample.
