The performance of new cryoprobes was studied by measuring the spatial and temporal patterns of the temperature distribution in liver tissue around one to three active cryoprobes. After 15 min of maximal freezing a tissue region 22 mm in diameter was frozen to temperatures below - 50 degrees C by one active cryoprobe. With three cryoprobes, using the synergistic cooling effect, a tissue region 45 mm in diameter was cooled to temperatures below - 50 degrees C. Optimal placement of the cryoprobes was found to be of critical importance.
通过测量一至三个有源冷冻探针周围肝组织中温度分布的空间和时间模式，对新型冷冻探针的性能进行了研究。在最大程度冷冻15分钟后，一个有源冷冻探针可将直径22毫米的组织区域冷冻至零下50摄氏度以下。使用三个冷冻探针，利用协同冷却效应，可将直径45毫米的组织区域冷却至零下50摄氏度以下。已发现冷冻探针的最佳放置至关重要。
