The present invention relates to devices and methods for measuring tissue temperature during thermal treatment of a body. More particularly, the present invention relates to a thermal probe comprising a plurality of thermal sensors operable to measure tissue temperatures during thermal treatments such as cryosurgery. Embodiments of the invention enable simultaneous measurements, using a single probe, of temperatures at a plurality of positions within body tissues. A preferred embodiment enables movement of sensors with respect to tissues while the probe is immobilized by being embedded in frozen tissue.

Multiple sensor device for measuring tissue temperature during thermal treatment

The present invention is of systems and methods for MRI-guided cryosurgery. The systems enable a surgeon positioned next to a patient and within an MRI magnetic environment both to monitor progress of a cryosurgical intervention by observing MRI images of the intervention in real time, and to fully control aspects of operation of a cryosurgery apparatus by remotely controlling a fluid supply source positioned external to that magnetic environment, which fluid supply source supplies cryogenic fluids to cryoprobes operable within that magnetic environment, thereby enabling real-time MRI-guided control of a cryoablation process. A preferred embodiment enables calculation and display of borders of an ablation volume surrounding a cooled cryoprobe in real time, and further enables automatic control of elements of a cryoablation procedure, which elements are triggered when shape and position of that calculated ablation volume are found to bear a predefined relationship to the shape and position of a predefined treatment target.
