RADIATION THERAPY PLANNING DEVICE AND RADIATION THERAPY PLANNING METHOD

摘要

A radiation therapy planning device is provided with a three-dimensional data collection unit that collects three-dimensional data indicative of a plurality of positions where a plurality of portions are arranged, a marker position measurement unit that measures the movement of a marker, and a dose calculation unit that, when therapy radiations changing in accordance with the movement of an examinee are irradiated to the examinee, calculates dose of the therapy radiations, which are irradiated to each of the portions, based on the movement and the three-dimensional data. This radiation therapy planning device can calculate more precisely a dose of therapy radiations irradiated to each portion of the examinee at the radiation therapy and, when the movement of a plurality of portions of the examinee is calculated, a dose of the radiations irradiated to the examinee can be reduced.
