title: [The place of ultrasonic tomography in irradiation planning (author's transl)].
abstract: Therapy-planning frequently requires cross-section sketches of the body in correct scale. The use of anatomic-topographic standard cross sections can lead to considerable errors in the estimation of the actual position of the organs and yields no information on the extension of the pathological process. The kidney, the bladder and the prostate were used as examples to demonstrate the capacity of ultrasonic tomography to supply all information, including body contour, relevant to therapy planning, as long as no limits are set to the procedure, as in the thorax area. Ultrasonic tomography can supplement but not replace the radiological procedure in therapy-planning.
