摘要：

There has been a resurgence of cryoablation for localized prostate cancer following several recent technological advances, most notably the monitoring of ice formation by real time transrectal ultrasound (TRUS). However, ultrasound can only identify the near surface of the ice and the sonographer is blind to the remainder of the ice formation and its three-dimension!al geometry. Moreover, there are no sonographic signs for the temperature distribution within the iceball. To be successful, therefore, the cryosurgeon must understand the growth of iceballs around various combinations of cryoprobes. We report on the geometry and thermal behavior of iceballs formed around one, two, three, and five 3.4-mm cryoprobes supplied by supercooled liquid nitrogen from a commercially available cryogenic unit, the Cryomedical Sciences Accuprobe.
