Claim 15:
16. The standardized artificial intelligence automatic radiation therapy planning method according to claim 1, wherein a method for constructing the dose prediction model comprises:
establishing a data set with a normalized PTV average dose, and formulating a scoring template based on the data set;
carrying out standardized naming for the region of interest;
dividing a 3D medical image into 2D slices as a training set and a test set;
reading out a beam angle of a 3D planned target volume data of the training set, and projecting the beam angle on the planned target volume to obtain a network weigh, and using a dose calculation algorithm to perform calculation on the network weight to obtain a beam channel;
constructing a Pix2pix dose prediction model using a U-net network or a V-net network as a generator, and a Markov discriminator as a discriminator;
using the 2D slice image as input of the generator, using predict dose and raw dose outputted by the generator as input of the discriminator, and outputting a discrimination result by the discriminator; and
inputting all 2D slices of the training set into the Pix2pix dose prediction model for training.
