TREATMENT PLANNING DEVICE, PLANNING TREATMENT SYSTEM, TREATMENT PLAN GENERATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To obtain verification and recording of accurate irradiation of therapeutic radiation to an affected part while improving convergence of the therapeutic radiation in radiation therapy.SOLUTION: A treatment planning device comprises: a condition acquisition unit for acquiring treatment conditions including a position of an affected part, a necessary radiation dose to the affected part, and a limitation radiation dose to a part other than the affected part; a first planning unit for planning a first irradiation to emit radiation to a first irradiation field including a whole of the affected part; and a second planning unit for generating a treatment plan that satisfies the treatment conditions by a combination of the first irradiation planned by the first planning unit and radiation irradiation to an irradiation field including only a part of the affected part.
