Development and Implementation of A Homogeneous and A Heterogeneous Anthropomorphic End to End Quality Assurance Audit System Phantom For Magnetic Resonance Guided Radiotherapy Modalities Ranging From 0.35 T to 1.50 T
… resonance (MR) guided radiation therapy (MRgRT) is an emerging field that integrates an MR imager with either a linear accelerator or three radioactive cobalt-60 sources. Before institutions participate in multi-institutional NCI-sponsored clinical trials, they are required to perform a …

Measurement of The Electron Return Effect Using Presage Dosimeter
<p>MR-guided radiation therapy (MRgRT) provides benefits such as superior soft tissue contrast, no imaging dose, and functional imaging capacities, but it also has concerns to be addressed. The electron return effect (ERE) refers to dose enhancement at the interface between different media, caused …

Polymer Gel Dosimetry in Magnetic Resonance-Image Guided Radiation Therapy
The integration of a magnetic resonance (MR) scanner with a radiation therapy treatment unit allows for adaptive radiotherapy guided by MR imaging (MR-IGRT) and has been proposed as an advanced radiotherapy treatment modality. The delineation of the tumor and adjacent organs is greatly improved by …
