Prostate biopsies

Computer-assisted prostate biopsies

Biopsies are performed when cancer is suspected. In the case of prostate cancer, trans-rectal biopsies are acquired under trans-rectal echographic control according to a pre-determined schema (for instance 12 samples taken from the gland). Because echographic control is bi-dimensional, accurately executing the planned schema is difficult. It is why we propose to guide passively biopsies based on registration of intra-operative data to data used for pre-planning. The challenge lies in the high mobility of the prostate; this requires developing real-time registration capabilities. A first very simplified version of the ProNav system allows interacting with the urologists.
