Abstract

The invention belongs to the field of radiotherapy and cloud computing services, and relates to a cloud Monte Carlo dose verification analysis method, a device, a storage medium and a system thereof.The method of the present invention comprises the steps of: (1) inputting a first radiotherapy plan, wherein the dose calculation result in the first radiotherapy plan is a first dose calculation result; (2) dose calculation is carried out based on a Monte Carlo calculation model: (3) the steps of interpolating, smoothing and re-sampling are performed on the dose distribution in the second dose calculation result to obtain a third dose calculation result; and (4) the dose distribution of the third dose calculation result from the Monte Carlo calculation is compared with the dose distribution of the first plan. The cloud Monte Carlo dose verification analysis method of the invention combines the cloud Monte Carlo with an optimized scheduling method, which can greatly improve the calculationefficiency and provide a satisfactory solution for the user; and the accuracy of the Monte Carlo calculation and the stability of radioactive source can be checked at any time to ensure the quality of the patient's exposure.

Description

technical field [0001] The invention belongs to the field of radiotherapy and cloud computing services, and relates to a cloud Monte Carlo dose verification analysis method, equipment and a storage medium. Background technique [0002] Radiation therapy, surgery, and chemotherapy constitute the three major treatment methods for tumors. Statistics at home and abroad show that 50-70% of cancer patients need to receive radiotherapy to varying degrees. [0003] The accuracy of radiotherapy ultimately depends on the dose distribution of the irradiated site, and accurate prediction of dose distribution is the key link in radiotherapy assurance. In particular, IMRT is highly conformal and the implementation process is complex. In the process of implementing intensity modulation, the accuracy of the scattered rays contributed by the sub-fields, the execution in place, and the penetration rate of the MLC blades must be considered; the shape of each sub-field The difference in accel...
