Abstract

The embodiment of the invention discloses a radiotherapy planning system and a storage medium. The system comprises a processor; the processor realizes the following steps in the working process: dividing a target area into at least two concentrically stacked rotating layer groups according to the shape of the target area, wherein the rotating layer group comprises at least two concentrically stacked rotating layers; the section of each rotating layer is a circular ring or a part of circular ring; the circle centre of the circular ring or the part of circular ring is located on the central axis of the target area; and the rotating layer group with the smallest radius is the largest regular body in the target area in the direction of the central axis; determining target dose distribution ofeach rotating layer group of the target area according to the prescription dose distribution of the target area; and determining plan parameters corresponding to each position of each rotating layergroup according to the target dose distribution of each rotating layer group so as to generate a radiotherapy plan of the target area. The problem that an existing radiotherapy method cannot accurately implement large-dose segmentation treatment 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...
