Radiotherapy dose comparing and displaying method and system

Abstract

The invention discloses a radiotherapy dose comparing and displaying method and system. According to the method, by obtaining reference dose values corresponding to different dose data of all kinds of coordinates, at the CT image position, of a cursor, reference isodose lines most approximate to the corresponding reference dose values among isodose lines corresponding to the different dose data of all the kinds are recognized respectively, the distance between the reference isodose line of each kind and the coordinates, at the CT image position, of the cursor is calculated, the reference isodose line with the shortest distance is used as a comparison isodose line, and other isodose lines except the isodose lines with the dose values the same as the dose value of the comparison isodose line among the isodose lines, on a CT image, of the cursor are hidden or / and the isodose lines with the dose values the same as the dose value of the comparison isodose line among the isodose lines are highlighted. Accordingly, a doctor can observe the isodose lines with the dose values the same as the dose value of the comparison isodose line among the corresponding isodose lines at the CT image position at a glance and compare the isodose lines, and the optimal radiotherapy scheme can be obtained 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...

Problems solved by technology

[0004] Based on this, it is necessary to provide an effective radiotherapy dose comparison display method and system for comparing dose distributions corresponding to different dose data in view of the difficulty of comparing different dose distributions.
