Background and purpose We conducted a prospective, in silico imaging clinical trial to
evaluate the feasibility and potential dosimetric benefits of computed tomography-guided …

Introduction Magnetic resonance guided radiotherapy (MRgRT) allows daily adaptation of
treatment plans to compensate for positional changes of target volumes and organs at risk …

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 …

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

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 …

Purpose Selection and development of image guided strategies for preoperative gastric
radiation therapy requires quantitative knowledge of the various sources of anatomic …

Simple Summary Adrenal metastases are frequent in solid malignancies such as lung
cancer and melanoma. Recent studies support the use of ablative local therapies in …

Background Volumetric reconstruction of magnetic resonance imaging (MRI) from sparse
samples is desirable for 3D motion tracking and promises to improve magnetic resonance …

Objective. The bowel is an important organ at risk for toxicity during pelvic and abdominal
radiotherapy. Identifying regions of high and low bowel motion with MRI during radiotherapy …
