The invention discloses a
dose prediction method and device for
robot radiotherapy equipment. The method comprises the steps: performing model training, and building a
patient model body according to a medical image of a patient; according to parameters of a treatment head of
robot radiotherapy equipment, calculating
dose distribution H of a single
radiation field of a patient die body by using a first
radiotherapy dose calculation method; according to the parameters of the treatment head of the
robot radiotherapy equipment, calculating
dose distribution L of the single
radiation field of the patient die body by using a second
radiotherapy dose calculation method; taking the L and the medical image of the patient as inputs, taking the H as an output, and sending the inputs into a
deep learning neural network for training to obtain a
radiotherapy dose prediction network; predicting doses, and calculating the
dose distribution L * of the single
radiation field of any patient die body by using a second radiotherapy
dose calculation method; and obtaining the
dose distribution H * of the single
radiation field of any patient die body, predicted by the output end of the radiotherapy
dose prediction network. The technical effect that one
algorithm is used for predicting the calculation result output by the other
algorithm is achieved through the
deep learning network.
