Problems solved by technology
The invention discloses a radiotherapy dose prediction method, which comprises the following steps of: preprocessing: establishing a patient model body according to the medical image of a patient; calculating the dose distribution H of radioactive particles in the patient model body by using a first calculation method of a radiotherapy dose; using a TG-43 method and a tissue heterogeneity correction method to obtain the dose distribution L of the radioactive particles in the patient model body; carrying out model training: taking multiple times of dose distribution L and the medical image of the patient as input, taking multiple times of dose distribution H as output, and sending into a deep learning neural network for training to obtain a radiotherapy dose prediction network; carrying out dose prediction: sending the medical image of any patient into the input end of the radiotherapy dose prediction network, and obtaining dose distribution L * by using the TG-43 method and the tissue heterogeneity correction method; and obtaining the dose distribution H *, which is predicted by the output end of the radiotherapy dose prediction network, of any one patient model body. According to the technical scheme disclosed by the invention, the technical effect of predicting the output result of a high-precision algorithm by using a low-precision algorithm is achieved.
