摘要： The object is to solve a problem that a skin dose, which is a dose for a skin, cannot visually be evaluated, and is to obtain a skin dose evaluation support apparatus that makes it possible to accurately and intuitively grasp a skin dose when a treatment plan is created. A skin dose evaluation support apparatus (320) is provided with a skin region contour creation unit (304) that creates skin region information including the boundary coordinates of a skin region, based on image data (306) to be input when a treatment plan for a radiation therapy for a patient is created; and a display calculation unit (305) that extracts a skin dose in a skin region, based on dose distribution data (311) calculated by a dose distribution calculation unit (303) of a treatment planning apparatus (102) and the skin region information, and creates display data (309) for displaying the extracted skin dose in a predetermined display format.

摘要： A sub beam approximation step in which a particle beam is approximated by a collection of a plurality of sub beams having Gaussian distribution and a sub beam dose distribution calculation step in which by simulating the state in which each sub beam of a plurality of sub beams is deflected by a scanning device and travelled, each sub beam dose distribution which is formed inside a patient by each sub beam is calculated, and a dose distribution which is formed inside a patient by the particle beam is obtained by adding the each sub beam dose distribution which is calculated are comprised.
