|Title:||TRACKING OBJECT RECOGNITION SIMULATOR OR MARKER RECOGNITION SIMULATOR, MOVING BODY TRACKING DEVICE, AND IRRADIATION SYSTEM|
Water equivalent thickness information for the inside of a subject (302) is determined from a CT image of the subject (302), and the possibility of recognizing a marker (304) and an X-ray imaging condition whereby the marker (304) can be recognized are computed on the basis of the calculated water equivalent thickness information in a computational processing device and displayed in a display device. An estimated movement range of the marker (304) is inputted, the water equivalent thickness information for the inside of the subject (302) is determined and a degree of recommendation of a marker (304) insertion position is calculated in the computational processing device and displayed in the display device. Through this configuration, a standard for an appropriate imaging condition for tracking a tracking object can be calculated at a pre-rehearsal stage, and the adoption rate of a marker used in tracking a moving body can be enhanced.
