Abstract

The invention relates to a dose determination system, a dose determination method and a computer readable storage medium. The method comprises the following steps of: acquiring a target radiotherapy plan of an object, wherein the target radiotherapy plan comprises sub radiotherapy plans corresponding to a rack angle; based on the sub-radiotherapy plan corresponding to the rack angle, determining a target flux graph corresponding to the rack angle, wherein the target flux graph comprises a plurality of first sub-regions, and each first sub-region corresponds to a first weight value; based on the first weight value corresponding to each first sub-region, determining the number of sampling particles corresponding to each first sub-region; and determining target dose distribution of the object at the rack angle according to a Monte Carlo algorithm on the basis of the number of the sampling particles corresponding to each first sub-region.

Description

technical field [0001] The present application relates generally to systems and methods of radiation therapy, and more particularly to systems and methods of dose determination in radiation therapy. Background technique [0002] Radiation therapy is widely used in cancer treatment by directing ionizing radiation at tumors. Considerations for radiation therapy include that during radiation therapy, the tumor receives sufficient radiation and that damage to organs at risk (OAR) is minimized as much as possible. Therefore, accurate calculation of the dose distribution of the irradiated part of the patient plays a decisive role in radiotherapy. The Monte Carlo calculation method has been widely used in medical dose calculation, which can accurately determine the dose distribution of the irradiated part of the patient, but the Monte Carlo calculation method has the disadvantages of slow convergence and long calculation time. Accordingly, it would be desirable to provide systems...
