Problems solved by technology

However, due to the large number of parameters, it takes a lot of time to modify repeatedly, and the degree of coincidence depends entirely on the judgment of the naked eye, without the support of theoretical data
The manual adjustment process for an accelerator usually takes about two days, which is very inefficient, not only brings a heavy workload to the staff, but also the accuracy is not stable enough

Embodiment Construction

[0057]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] The purpose of the present invention is to realize the automatic matching of the dose distribution simulated by the dose model of the TPS software and the dose distribution actually produced by the accelerator, improve the matching accuracy, and reduce the matching time consumption. First of all, in order to facilitate the description a...

Abstract

The invention provides a dose model matching method and a system. The method comprises following steps: a, a measure dose curve is obtained and a simulative dose curve is calculated according to a parameter of transactions per second (TPS); b, a matching degree between the measure dose curve and the simulative dose curve is calculated and the matching degree needs to be judged whether the matching degree is larger than a first threshold value; c, if the matching degree is larger than the first threshold value, the parameter of the TPS is regulated and the simulative dose curve is recalculated according to the regulated parameter of the TPS; d, the step b and the step c are carried out repeatedly until the matching degree is not larger than the first threshold value, and then the process is over.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a dose model matching method and system. Background technique [0002] Radiotherapy TPS (Treatment Planning System) software is a medical software currently used in the radiotherapy process. Its function is to formulate a more reasonable treatment plan by simulating the dose distribution generated by the radiation irradiated on the human body during the radiotherapy process. Therefore, for TPS, the most important thing is that the simulation results should be as consistent as possible with the dose distribution of the human body irradiated by the radiation generated by the accelerator during the actual treatment process. The higher the consistency between the two, the better the performance of the TPS software. [0003] In order to ensure the accuracy of TPS software, there will be another debugging process during the use of TPS. That is, the phantom will be actually ir...
