    摘要: The present invention is a system for placing cryoprobes in a treatment area of a human patient. The system includes a computer system for displaying an image of a treatment area, a template of suggested cryoprobe palcements in the treatment area and images of actual cryoprobes placed within treatment area. The computer system is programmed to perform the steps of: acquiring the image of the treatment area, determining desired dimensions of the treatment area based on the image of the treatment area, determining the optimal cryoprobe placements in the treatment area based on the determined desired dimensions to provide the template of suggested cryoprobe placement, acquiring the images of actual cryoprobes placed within the treatment area, and overlaying the template of suggested cyroprobe placements on the acquired images of actual cryoprobes. The resulting overlaying is provided on a display of the computer system, thereby allowing the surgeon to compare the actual cryoprobe palcements with the optimal cryoprobe placements as determined by the computer system.

    摘要: A system and method for performing cryosurgery of the prostate while protecting surrounding tissue. Cryosurgical probes are provided with argon gas for cooling and with helium for warming. Probes are inserted into the prostate and supplied with argon gas for cooling, while probes inserted into the surrounding tissue and supplied with helium gas for warming. The warmed probes protect the surrounding tissue from freezing.
