Abstract

A cryosurgical system for assisting an operator in placing and operating cryosurgical probes in the prostate of a human patient. The cryosurgical system includes a computer system being programmed with software capable of performing the following steps: a) capturing a plurality of transverse views of the prostate; b) capturing a sagittal view of the prostate; c) outlining the capsule of the prostate, the urethra and the rectal wall of the patient with the assistance of the operator, utilizing the captured plurality of transverse views and the captured sagittal view; d) constructing a 3-dimensional model of the prostate, the urethra and the rectal wall utilizing the outlines of step c), above; and, e) utilizing the 3-dimensional model of the prostate, the urethra and the rectal wall to determine i) the number of cryosurgical probes to be utilized; ii) probe settings; and, iii) probe placement positions. The resultant ice thus produced by the cryosurgical probes is optimized for a specific patient.
