International ClassA61B 005/055AbstractA magnetic resonance surgery system facilitates performance of surgery with a focussed ultrasound transducer that selectively destroys tissue in a region within a subject. The focussed ultrasound transducer dissipates ultrasonic energy at a focal point within the region of tissue to be destroyed. A number of hydraulic positioners position the focal point under the control of a surgeon. A magnetic resonance imaging system employing a temperature sensitive pulse sequence creates an image of the tissue and the region being heated to allow the surgeon to adjust the position of the ultrasonic transducer so as to direct ultrasonic energy to the appropriate location.Field of SearchSpectrometer components | |
