Development of Advanced Mr-Guided Adaptive Radiation Therapy Methods For Head & Neck Cancers On The 1.5T Mr-Linac
<p> The 1.5T hybrid MRI/linear accelerator (MR-linac) has recently been introduced into clinical practice and used for the treatment of head and neck cancers (HNC). This device enables on-line adaptive radiation therapy (ART) based on anatomical changes throughout treatment and variations in …

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 …

Physical and biological characterisation of clinically relevant combined MRI-radiation exposures with conventional and nanoparticle contrast agents
Background:<br/>MR-Linacs provide a unique opportunity for MRI contrast agents to be investigated, not only for the ability to enhance contrast, but for their potential radiosensitising properties to improve radiotherapy treatments. Metal-based nanoparticle contrast agents have a preferential …

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
… </strong>Magnetic 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, …
