Method, device, and program for calculating brachytherapy plan, and brachytherapy apparatus

Abstract

The present invention relates to a method, a device, and a program for calculating a brachytherapy plan, and a brachytherapy apparatus. The method comprises: a step in which a computer obtains the number of radiation irradiation spots on the basis of radiation irradiation information (a radiation irradiation spot number obtaining step (S200)); a step in which the computer obtains target area information from a body model of a patient generated on the basis of medical image data of the patient (a target area information obtaining step (S400)); and a therapy plan calculating step (S600) in whichthe computer calculates, on the basis of the radiation irradiation information and the target area information, the radiation irradiation spots to which radiation is irradiated and the time length ofirradiation to each radiation irradiation spot.

Description

technical field [0001] The present invention relates to a brachytherapy plan calculation method, device and program, and a brachytherapy device, and more specifically relates to a method for calculating brachytherapy by using a treatment device inserted into the body and controlling the position and direction of radiation irradiation. Methods, devices and procedures for treatment planning and radiation therapy devices including the same. Background technique [0002] Radiation therapy for cancer patients can be roughly divided into two types. They are external beam radiation therapy, in which radiation is delivered to the tumor from a source outside the patient's body, and brachytherapy, in which radiation is delivered from a radiation source inside the patient. [0003] Among them, the advantage of brachytherapy is that since a radiation source is inserted into the tumor to deliver the treatment dose, a very high radiation dose is delivered to the tumor, but the radiation ...

AI Technical Summary

Problems solved by technology

[0004] In brachytherapy, radiation is irradiated by moving a radiation source with a treatment tool inserted into the body, but there is a problem in that the technology to adjust the three-dimensional radiation intensity by adjusting the radiation irradiation direction in the treatment tool has not been sufficiently developed

Also, when performing brachytherapy, it is also necessary to minimize the dose affecting normal tissues, and it is necessary to minimize the time required for brachytherapy, but there is a problem that there is no solution to this problem
