Abstract
A gantry applies particle beams to a subject. An ultrasonic diagnostic apparatus scans the subject with ultrasonic waves via an ultrasonic probe, and acquires an ultrasonic image concerning a radiotherapy target region of the subject. A processing circuitry specifies a first planned point of a Bragg peak in the ultrasonic image, which anatomically coincides approximately with a second planned point of the Bragg peak decided in radiotherapy planning. The processing circuitry estimates a sighting point of the Bragg peak of a particle beam based on a body surface position of the subject and an actual range of the particle beam. The display displays the ultrasonic image to indicate the first planned point and the sighting point.
