Abstract

The embodiment of the present invention discloses a radiotherapy planning system and a storage medium, the system includes a processor: the processor implements the following steps during operation: determine the target according to the radial radius of the target area and the radial thickness of the rotating layer Rotary layer distribution of the area, wherein, the target target area is formed by concentric lamination of at least two rotating layers, the cross-section of the rotating layer is a ring or a partial ring, and the center of the ring or a partial ring is located at the on the central axis of the target target area; determine the target dose distribution of each rotation layer of the target target area according to the prescription dose distribution of the target target area; determine the target dose distribution of each rotation layer according to the target dose distribution of each rotation layer The planning parameters corresponding to each position are used to generate the radiotherapy plan of the target target area, wherein the planning parameters include beam current parameters and blade pair matching information of the rotating layer. It solves the problem that it is difficult to balance the conformity of the target area and the dose utilization rate in the existing radiation therapy method.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer software, in particular to a radiotherapy planning system and a storage medium. Background technique [0002] Radiation therapy for tumors is generally divided into multiple sessions (about 35 sessions), and the entire treatment period may last for several weeks in order to restore the irradiated healthy tissue. If the healthy tissue is irradiated with a lower dose rate through more precise control, it becomes possible to apply more doses to tumor tissue each time, so that the total number of treatments will be reduced, and the entire treatment can be completed at least once. Periodic dose, this program is called a high-dose fractionation (Hypofractionation) program. [0003] At present, the commonly used radiation therapy method is IMRT (intensity-modulated radiation therapy, referred to as IMRT, intensity-modulated radiation therapy, that is, intensity-modulated radiation thera...
