Abstract
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.
