Magnetic resonance-guided set up images (MRg-images) acquired prior to daily treatment provide longitudinal image series that could contain treatment response information. The purpose of this work is to compare delta radiomics texture features (DF) extracted...
To compare the traditional Computed Tomography Dose Index (CTDI) and the Cone-Beam-Dose-Index (CBDI), an alternative metric that quantifies the average dose in the central region of a cone-beam CT (CBCT) scan, for imaging dose measurements on bore-based linac...
The Varian Ethos intelligent optimization engine (IOE) automates the generation of non-overlapping optimization structures and resolves planning conflicts via a prioritized goal hierarchy. While designed to minimize manual intervention, the influence of user-...
Metal artifacts caused by implanted gold fiducial markers remain a significant challenge in cone-beam CT (CBCT) imaging for prostate radiotherapy. Their high attenuation generates severe streaks and image distortions that decrease overall image quality. This...
Accurate delineation of anatomy on cone-beam CT (CBCT) is essential for image-guided and adaptive radiotherapy in head and neck cancer, yet image quality and deformable image registration (DIR) performance remain limiting. This study evaluated accuracy of sup...
