Objective:Topredict the three-dimensional dose distribution of regions of interest (ROI) with brachytherapy for cervical cancer based on U-Net fully convolutional network, and evaluate the accuracy of prediction model.Methods:First, 100 cases of cervical cancer intracavity combined with interstitial implantation were selected as the entire research data set, and divided into the training set (
n=72), validation set (
n=8), and test set (
n=20). Then the U-Net was used to construct two models based on whether the uterine tandem and the implan...
