Patent ID: 7945019

Claim:
A method for monitoring an instrument for thermal treatment of body tissue of a particular region of a human body, the method comprising: producing at least one reference exposure of a region to be treated with an X-ray machine; performing a thermal treatment on the region; producing at least one check exposure of the region with the X-ray machine, wherein the at least one check exposure is produced as a partial volume exposure of the region, and wherein the step of producing the at least one check exposure provides a lower radiation dose than that used for the reference exposure by producing two exposures from two angular positions of a gantry having an X-ray tube and an X-ray detector and being adapted to rotate about the region being treated, wherein the two angular positions are displaced from each other by an angle of 90°; and producing at least one temperature-change profile by comparing the at least one check exposure with the at least one reference exposure.
