MR-only radiotherapy (RT) planning faces workflow challenges that limits its use in routine practice. Currently, clinics rely on manual contouring and/or deep learning based automatic segmentation (DLAS) trained using clinical-specific MRI sequences. The form...

Synthetic CT (sCT) derived from CBCT images show potential to facilitate online adaptive radiotherapy (oART) by enhancing CBCT image quality. Compared to sCT from a 2D deep-learning (DL) model that can result in through-plane streak artifacts, we evaluate a 2...

Online adaptive prostate MR-guided radiotherapy (MRgRT) is time-sensitive, and contouring with structure preparation can require upwards of 15 minutes per fraction. While vendor-TPS provided contours can be useful, performance and consistency vary by site, pr...
