The commissioning and quality assurance of an MR-Linac presents medical physicists with many technical and dosimetric challenges. Having a 3D water phantom system is beneficial for saving time and for enhanced data acquisition.

In this webinar, Joshua Kim of Henry Ford Hospital, will share his experience using the BEAMSCAN MR 3D water phantom for commissioning and quality assurance measurements of the ViewRay MRIdian MR-Linac. He will provide an overview of the ViewRay MRIdian system, address the technical challenges in beam data acquisition during commissioning, and explain how these can be overcome using the BEAMSCAN MR 3D water phantom.

Key topics covered in the webinar include:

• Technical overview of the ViewRay MRIdian system.
• Dosimetric challenges of MR-Linacs and how to overcome them using BEAMSCAN MR.
• Current workflow for commissioning and acceptance testing, including areas for increasing efficiencies.
• Quality assurance workflow using BEAMSCAN MR:
  – Phantom set-up for measurements.
  – Beam data acquisition – profile and PDD measurements with different detectors.
  – Small field measurements using PTW’s microDiamond detector.
  – Transmission reference detector.
  – Comparison and validation of data.
• Routine machine QA measurements.

Don’t miss this opportunity to gain valuable tips and advice on commissioning and QA measurements on the ViewRay MRIdian MR-Linac.

Joshua Kim holds a PhD in biomedical sciences/medical physics from Oakland University. He is board-certified in therapeutic medical physics, and currently serves as a medical physicist at Henry Ford Health System, Department of Radiation Oncology, Detroit (MI), USA, where he is also responsible for commissioning and quality assurance of the ViewRay MRIdian MR-Linac. His clinical work and research interests include new modalities for simulation imaging and image-guided radiotherapy, with a focus on online adaptive radiotherapy.
