Abstract

The embodiment of the invention discloses a radiotherapy planning system and a storage medium. The system includes a processor. When the processor works, the following steps are realized: determiningrotating layer distribution of a target area according to the radial radius of the target area and the radial thickness of a rotating layer, the target area being formed by concentrically stacking atleast two rotating layers, the cross section of each rotating layer being a circular ring or a partial circular ring, and the circle center of the circular ring or the partial circular ring being located on the central axis of the target area; determining target dose distribution of each rotating layer of the target area according to the prescription dose distribution of the target area; accordingto the target dose distribution of each rotating layer, determining plan parameters corresponding to each position of each rotating layer to generate a radiotherapy plan of the target area, wherein the plan parameters include beam parameters and blade pair matching information of the rotating layers. The problem that the conformity of a target area and the dosage utilization rate are difficult toconsider in an existing radiotherapy method is solved.

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] Tumor radiation therapy is generally divided into multiple implementations (about 35 times), 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 therap...
