Patent number: 11972854Abstract: There is provided a radiotherapy system, a data processing method and a storage medium. The radiotherapy system includes a calibration database, a training module and a data processing module. The calibration database can acquire a plurality of the sample data generated in a clinical therapy process. The training module can perform deep learning on the plurality of sample data stored in the calibration database to obtain a therapy algorithm model. The data processing module can process the detection data received in the clinical therapy process according to the therapy algorithm model to generate preliminary therapy data. As the therapy algorithm model is obtained by performing deep learning on a large amount of clinical data, the reliability of the therapy algorithm model is high. Accordingly, the accuracy of the preliminary therapy data generated by the therapy algorithm model is also high.Type: GrantFiled: June 5, 2017Date of Patent: April 30, 2024Assignee: OUR UNITED CORPORATIONInventors: Hao Yan, Jiuliang Li, Jinsheng Li, Peng Zan, Haifeng Liu
