Claim Text:
1. A treatment planning system comprising: a computer, including a processor and a memory, coupled to a particle beam therapy system; an input device coupled to the computer; a display device, coupled to the computer, which displays information of a treatment plan calculated by the computer; a storage unit, coupled to the computer, which stores a series of three-dimensional CT images that include information of variations of a target region to be irradiated with radiation of the particle beam therapy system, wherein the memory stores irradiation parameters input via the input device for irradiating the target with the radiation of the particle beam therapy system, wherein the computer is programmed to: associate the three-dimensional CT images of the series of three-dimensional CT images with information relating to time that has elapsed from a beginning to an end of a radiation treatment based on the calculated treatment plan, interpolate the information of the variations of the target region based on the information relating to the elapsed time and based on the series of three-dimensional CT images for each time period during which the radiation is to be applied, and calculate a dose distribution based on the interpolated information of the variations of the target region.
