Radiation dose prediction for pancreatic stereotactic body radiotherapy via convention neural networks

In this study, we propose a novel deep learning-based method to predict dose distribution based on patient’s pancreas planning CT and organ contours. To comprehensively extract features from CT and contours, dual pyramid networks (DPNs) with late fusion network (LFN) are used. The proposed network consists of three subnetworks, i.e., CT-only feature pyramid network (FPN), contour-only feature pyramid network (FPN) and late fusion network (LFN)....
