Dose prediction using a deep neural network for accelerated planning of rectal cancer radiotherapy

Purpose To apply a deep neural network to predict dose distributions of rectal cancer patients for accelerated volume modulated arc technique (VMAT) planning. Materials and methods Computed tomography scans and approved VMAT plans together with Doseapproved of 187 patients treated from February 2018 to April 2019 were randomly selected for this retrospective study. The deep neural network DeepLabv3+ was applied for dose distribution prediction....
