Radiation therapy is a major component of cancer treatment pathways worldwide. The main
aim of this treatment is to achieve tumor control through the delivery of ionizing radiation …

High quality radiation therapy requires highly accurate and precise dose delivery. MR-
guided radiotherapy (MRgRT), integrating an MRI scanner with a linear accelerator, offers …

Purpose To develop a geometry‐informed deep learning framework for volumetric MRI with
sub‐second acquisition time in support of 3D motion tracking, which is highly desirable for …

Simultaneous multi-slice (SMS) is a magnetic resonance imaging (MRI) acceleration
technique that utilizes multi-band radio-frequency pulses to simultaneously excite and …

Purpose To propose a framework called live‐view golden‐angle radial sparse parallel
(GRASP) MRI for low‐latency and high‐fidelity real‐time volumetric MRI. Methods Live‐view …

Abdominal organ motions introduce geometric uncertainties to radiotherapy. This study
investigates a multi-temporal resolution 3D motion prediction scheme that accounts for both …

Objective. Precision radiation therapy requires managing motions of organs at risk that occur
during treatment. While methods have been developed for real-time respiratory motion …

Objective. Online adaptive radiotherapy has demonstrated improved dose conformality in
response to inter-fraction geometric variations in the abdomen. The dosimetric impact of …

Background Gastrointestinal (GI) tract motility is one of the main sources for intra/inter‐
fraction variability and uncertainty in radiation therapy for abdominal targets. Models for GI …

Background and purpose For accurate pre‐operative gastric radiotherapy, intrafractional
changes must be taken into account. The aim of this study is to quantify local gastric …
