Abstract

A manually positioned focussed energy transducer system facilitates medical procedures by allowing a physician to manually position the focal point of the focussed energy transducer to a selected tissue. The focal point of the focussed energy transducer is the location which tissue is destroyed when the energy transducer is activated. A tracking device tracks the position and orientation of the ultrasound transducer. An MR imaging system creates an image of internal structures of the patient near the location of the energy transducer. A superposition device receives the position and orientation of the ultrasound transducer from the tracking device and superimposes a symbol on the image corresponding to the position of the energy transducer relative to the patient. This allows the physician to adjust the position of the energy transducer to the appropriate location without the need for energizing the energy transducer.
