Characterizing MR Imaging isocenter variation in MRgRT

Biomedical Physics & Engineering Express, 2020
We characterized MRI isocenter variation at various gantry positions in two 0.35 T MRgRT systems using two independent methods. First, image center-based quantification was employed on 3D volumetric and 2D cine images of a 24 cm diameter spherical phantom at various gantry positions in the MRI QA mode. The center of the phantom images was identified to

Role of MR-guided Radiotherapy (MRgRT) in Colorectal Cancer

Current Colorectal Cancer Reports, 2021
The current standard treatment for locally advanced or metastatic colorectal cancer often includes radiotherapy delivered under computed tomography (CT)–based image guidance. Magnetic resonance–guided radiotherapy (MRgRT) offers a substantial improvement in target and adjacent organ visualization and allows for real-time imaging throughout treatment to

A Multi-Centric Evaluation of AI-Driven OARs Low Field MRgRT Pelvic /Abdomen Contouring

International Journal of Radiation Oncology*Biology*Physics, 2022
Purpose/Objective(s) Organs at risk annotation is a strong bottleneck of Magnetic resonance imaging guided radiotherapy (MRgRT) in the context of adaptive treatment. It is a time-consuming task that reduces patient throughput (20% of the fraction duration dedicated to contouring) while suffering standardization and reproducibility across physicians ...
