TREATMENT PLANNING SYSTEM, DEVICE FOR CALCULATING A SCANNING PATH AND PARTICLE THERAPY SYSTEM
First Claim
1. A treatment planning system for creating treatment plan information for particle therapy, comprising:
- an input device;
an arithmetic device for performing arithmetic processing based on a result of input to the input device and creating treatment plan information; and
a display device for displaying the treatment plan information;
wherein the arithmetic device calculates a scanning path by setting a pre-specified optional direction as a main direction for scanning irradiation positions with an ion beam using scanning magnets.

Abstract
In a particle therapy treatment planning system for creating treatment plan data, the movement of a target (patient'"'"'s affected area) is extracted from plural tomography images of the target, and the direction of scanning is determined by projecting the extracted movement on a scanning plane scanned by scanning magnets. Irradiation positions are arranged on straight lines parallel with the scanning direction making it possible to calculate a scanning path for causing scanning to be made mainly along the direction of movement of the target. The treatment planning system can thereby realize dose distribution with improved uniformity.
