Ohio 43699-0008 Cryoablation therapy is a method of minimally invasive cancer treatment through use of liquid nitrogen to freeze and consequently to destroy tumors. Though cryoablation has been used for some time, the behavior of the cryoprobe system has not been extensively studied. For example, in prostate cancer treatment, the settings of the cryoprobe to achieve a frozen area of appropriate size and shape were developed empirically. This isotherm is depicted visually with reference to the surrounding tissue. Within the simulator, the user may move the probes, change cryoprobe settings and adjust their viewpoint.
Initial simulations show reasonable conformity to known results.
Future work includes further verification tests and integration into a mechanically driven system using CryoSim optimized placements.
