Synthetic CT‐aided multiorgan segmentation for CBCT‐guided adaptive pancreatic radiotherapy

The delineation of organs at risk (OARs) is fundamental to cone-beam CT (CBCT)-based adaptive radiotherapy treatment planning, but is time consuming, labor intensive, and subject to interoperator variability. We investigated a deep learning-based rapid multiorgan delineation method for use in CBCT-guided adaptive pancreatic radiotherapy.To improve the accuracy of OAR delineation, two innovative solutions have been proposed in this study. First,...
