Deep learning‐based dose prediction for low‐energy electron beam superficial radiotherapy

Precision Radiation Oncology, Volume 9, Issue 2, Page 108-119, June 2025.
This study integrates Monte Carlo (MC) simulations with a cascaded 3D‐UNet (C3D) deep learning model to achieve rapid and accurate dose predictions for low‐energy electron radiotherapy. Utilizing CT phantoms of six body sites, the model demonstrates high prediction accuracy with a Gamma pass rate exceeding 92% within 1%/1mm tolerance and a ...
