An Ultra-Fast Dose Calculation Algorithm with Transformer Neural Networks: Model Fine-Tuning and Validation
Fast and accurate dose calculation is a key requirement for real-time adaptive radiotherapy, particularly for emerging image-guided radiation therapy systems. Monte Carlo methods and existing treatment planning system (TPS) algorithms do not achieve the compu...

Cross-Treatment Knowledge Transfer: Generalizability of a Deep Learning Autosegmentation Model Trained on External Beam Contours for Brachytherapy
To evaluate the generalizability of a deep learning (DL)-model, trained exclusively with external beam radiotherapy (EBRT) organs‑at‑risk (OARs) contours, for autocontouring in cervical cancer brachytherapy (CC-BT).

PCA-Based Future Image Frame Prediction for Real-Time MRI-Guided Radiotherapy
MRI-radiotherapy hybrid systems enable real-time guidance of the therapeutic beam by dynamically adapting to tumor motion. However, inherent delays in imaging and beam control demand prediction of the tumor’s future position and shape for accurate targeting....
