Experimental small fields output factors determination for an MR-linac according to the measuring position and orientation of the detector

Biomedical engineering and physics express
Purpose. To investigate the effect of the position and orientation of the detector and its influence on the determination of output factors (OF) for small fields for a linear accelerator (MR-linac) integrated with 1.5 T magnetic resonance following the ...

Multileaf collimator characterization and modeling for a 1.5 T MR-linac using static synchronous and asynchronous sweeping gaps

Physics in Medicine and Biology
Objective. The Elekta unity MR-linac delivers step-and-shoot intensity modulated radiotherapy plans using a multileaf collimator (MLC) based on the Agility MLC used on conventional Elekta linacs.

Current Status of MR-Linac System.

Igaku butsuri : Nihon Igaku Butsuri Gakkai kikanshi = Japanese journal of medical physics : an official journal of Japan Society of Medical Physics, 2018
Current status of MR-Linac System was reported. First, we introduced the history of development about MR-Linac System. We discussed the advantage of MR-Linac for radiotherapy. Next, we explained the electron return effect caused by magnetic field, resulting in different dose distribution, compared to dose distribution with no magnetic field.

Dose accuracy for the MR-linac

The introduction of the MR-linac marked a major milestone in the field of radiotherapy. The MR-linac uses a linear accelerator (Linac) combined with an MRI scanner. MRI allows excellent soft-tissue visualization, and the integrated system enables 3D imaging immediately before and during treatment.

MRgRT Quality Assurance for a Low-Field MR-Linac

Seminars in Radiation Oncology
The introduction of MR-guided treatment machines into the radiation oncology clinic has provided unique challenges for the radiotherapy QA program. These MR-linac systems require that existing QA procedures be adapted to verify linac performance within the magnetic field environment and that new procedures be added to ensure acceptable image quality ...
