Abstract

The invention discloses a radiation therapy dose comparison display method and system. By obtaining the reference dose value corresponding to each different dose data of the coordinate point of the cursor on the CT image position, the isodose lines corresponding to each different dose data are respectively identified. The reference isodose line closest to the corresponding reference dose value, calculate the distance between each reference isodose line and the coordinate point of the cursor on the CT image position, and use the reference isodose line with the smallest distance as the contrast isodose line, Hide the isodose line of the cursor on the CT image, the dose value in the isodose line is the same as the dose value of the contrast isodose line, other isodose lines other than the isodose line or / and highlight the dose value in the isodose line and the contrast, etc. A dose line is an isodose line with the same dose values. In this way, the doctor can observe at a glance the isodose line with the same dose value in the isodose line corresponding to the CT image position and the dose value of the contrast isodose line and compare it, so as to obtain the optimal radiotherapy plan more accurately.

Description

technical field

[0001] The invention relates to the field of medical radiotherapy, in particular to a radiotherapy dose contrast display method and system. Background technique

[0002] In the field of tumor radiotherapy, radiologists need to formulate radiotherapy plans for patients based on radiation exposure, and radiotherapy physicists design radiotherapy plans through the treatment planning system (Treatment Planning System, TPS), which includes the physical dose absorbed by the patient's body The three-dimensional dose distribution in the patient's body and the parameters of the treatment field. The treatment field parameters mainly include the motion parameters of the moving parts of the accelerator when the accelerator that generates therapeutic radiation is used to irradiate the tumor site with radiation therapy, such as the incident angle of radiation and the radiation field. Shape, radiation energy, number of jumps, number of total points of irradiation, etc. The...
