ABSTRACT:
An automatically positioned focussed energy transducer system facilitates medical procedures by allowing a physician to interactively view the position the focal point of a focussed energy transducer superimposed upon a medical image and computer generated model of internal structures of a patient. A tracking device tracks the position and orientation of the ultrasound transducer. A medical imaging system creates an image of internal structures of the patient near the location of the energy transducer. A general purpose computer either receives a model of internal structures constructed in advance, or employs a medical imaging device to create the model. The general purpose computer displays selected surfaces of the model in an orientation and view which coincides with the medical image acquired. A superposition device receives the position and orientation of the ultrasound transducer from the tracking device and superimposes a symbol on the images corresponding to the position of the energy transducer relative to the patient. The physician then selects an internal structure to be destroyed which the general purpose computer determines the locations which the focal point must scan in order to destroy the structure. An actuator, coupled to the general purpose computer causes the focal point of the energy transducer to scan these locations which the physician adjusts the intensity of energy provided to the focal point by an input device.
