ABSTRACT:
A therapy system for treating pathological tissue with heating radiation includes an ultrasound locating system and a catheter introducible into the body of a patient to be treated, the catheter having at least one pressure sensor in the region of its distal end. The catheter is used to apply the heating radiation to a specified site within the patient. The pressure sensor generates signals due to interaction with the diagnostic ultrasound waves of the ultrasound locating system, and these signals are supplied to an image generating unit within the ultrasound locating system. The image generating unit calculates the position of the pressure sensor in the ultrasound image on the basis of the signals from the pressure sensor, and mixes a mark into the displayed image at the appropriate location, so that the position of the catheter is thereby identifiable.
