TI  - Practical guidelines of online MR-guided adaptive radiotherapy.

AB  - The first magnetic resonance (MR)-guided radiotherapy system in Japan was 
      installed in May 2017. Implementation of online MR-guided adaptive radiotherapy 
      (MRgART) began in February 2018. Online MRgART offers greater treatment accuracy 
      owing to the high soft-tissue contrast in MR-images (MRI), compared to that in 
      X-ray imaging. The Japanese Society for Magnetic Resonance in Medicine (JSMRM), 
      Japan Society of Medical Physics (JSMP), Japan Radiological Society (JRS), 
      Japanese Society of Radiological Technology (JSRT), and Japanese Society for 
      Radiation Oncology (JASTRO) jointly established the comprehensive practical 
      guidelines for online MRgART. These guidelines propose the essential requirements 
      for clinical implementation of online MRgART with respect to equipment, 
      personnel, institutional environment, practice guidance, and quality 
      assurance/quality control (QA/QC). The minimum requirements for related equipment 
      and QA/QC tools, recommendations for safe operation of MRI system, and the 
      implementation system are described. The accuracy of monitor chamber and detector 
      in dose measurements should be confirmed because of the presence of magnetic 
      field. The ionization chamber should be MR-compatible. Non-MR-compatible devices 
      should be used in an area that is not affected by the static magnetic field 
      (outside the five Gauss line), and their operation should be checked to ensure 
      that they do not affect the MR image quality. Dose verification should be 
      performed using an independent dose verification system that has been confirmed 
      to be reliable through commissioning. This guideline proposes the checklists to 
      ensure the safety of online MRgART. Successful clinical implementation of online 
      MRgART requires close collaboration between physician, radiological technologist, 
      nurse, and medical physicist.
