    Evaluation of Deep Learning to Augment Image-Guided Radiotherapy for Head and Neck and Prostate Cancers
  3. 2023
    “…PURPOSE: This study focused on predicting 3D dose distribution at high precision and generated the prediction methods for nasopharyngeal carcinoma patients (NPC) treated with Tomotherapy based on the patient-specific gap between organs at risk (OARs) and planning target volumes (PTVs). METHODS: A convolutional neural network (CNN) is trained using the CT and contour masks as the input and dose distributions as output. …”
