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-...
To evaluate and compare the incidence of xerostomia (“dry mouth”) in head and neck (H&N) cancer patients treated with intensity-modulated proton therapy (IMPT) and intensity-modulated radiation therapy (IMRT), across unilateral (UT) and bilateral (BT) treatme...
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...
Radiomics, a field of quantitative characterization of tumor heterogeneity and has shown promise for predicting treatment response in hepatocellular carcinoma (HCC). Delta-radiomics extends this approach by capturing temporal changes in radiomic features (RFs...
Quantitative PET imaging biomarkers such as metabolic tumor volume (MTV) and maximum standardized uptake value (SUVmax) have demonstrated prognostic value in lymphoma; however, these metrics fail to characterize intratumor heterogeneity. This study aimed to a...
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...
Radiation segmentectomy using yttrium-90 (Y‑90) transarterial radioembolization (TARE) is an established treatment for hepatocellular carcinoma (HCC), with the goal of achieving complete tumor necrosis through delivery of high doses (>400 Gy). Despite widespr...
Portable MRI (pMRI) systems provide a compact, cryogen-free, and infrastructure-light platform for point-of-care and in-house clinical and preclinical imaging without patient or animal transport. However, the low magnetic field strength of pMRI inherently lim...
