A magnetic resonance imaging (MRI) guided surgical system is provided that includes one or more surgical tools having components configured to develop reactive effects when exposed to MR signals generated by the MRI system. The system includes a control system that can determine whether the MR system is generating MR signals, and if the control system determines that the MR system is generating MR signals, mitigates the reactive effects of MR signals on components of the surgical tools. The system can include a cryoablation system with a cryoprobe having a probe shaft being made of a metallic material. If the control system determines that the MR system is generating MR signals, the control system can electrically disconnect the cryoprobe and/or ignore electrical signals generated by the electric heater in response to exposure to MR signals, and/or initiate a cooling operation of the probe shaft, whereby the cooling operation.提供一種磁共振成像(MRI)引導式手術系統，其包括一或多個手術工具，該一或多個手術工具具有經組配以在暴露於由該MRI系統產生之MR信號時發生電抗性效應之組件。該系統包括一控制系統，該控制系統可判定MR系統是否在產生MR信號，且若該控制系統判定該MR系統在產生MR信號，則減輕MR信號在該等手術工具之組件上之電抗性效應。該系統可包括一具有一冷凍探針之冷凍切除系統，該冷凍探針具有一由金屬材料製成之探針軸。若該控制系統判定該MR系統在產生MR信號，則該控制系統可將該冷凍探針電斷開且/或忽略回應於暴露於MR信號而由電加熱器產生之電信號，且/或起始該探針軸之冷卻操作，其中該冷卻操作。
