The MRIdian Linac System


MRI-Guided Radiation Therapy, Now with a LINAC

MRIdian Linac Technology Overview


Advanced treatment deliverySupport for advanced and conventional radiation therapy techniques, including IGRT, SRS and SRT, IMRT, and 3D conformal therapy.

Pretreatment imagingHigh-quality, volumetric soft- tissue imaging for accurate pretreatment positioning.

On-table dose prediction and adaptive optimization—Accurate dose prediction for on-table quality assurance and plan adaptation.

Soft-tissue targetingContinuous, MRI-guided soft-tissue tracking and automatic beam control during treatments.

Review and assessmentSoftware tools that help physicians better understand and manage the progress of treatment.

MRIdian® Linac is ViewRay’s latest breakthrough technology. This next generation radiotherapy technology integrates a 6 MV linac with 0.35 T MRI technology in a compact design, together with our proprietary software to locate, target and track the position and shape of tumors while the radiation is delivered.

The MRIdian Linac can provide continuous MR based soft-tissue imaging during linac-based radiation treatment. It builds on the success of the MRIdian® system, the world’s first and only clinical MRI guided radiation therapy system that can image and treat simultaneously with no additional imaging dose to the patient.

MRIdian Linac offers a clinically proven on-table MRI-guided adaptive, automated and integrated treatment planning system that uses a linac to deliver modulated radiation therapy.

MRIdian Linac uses the same split-magnet MRI system used in the MRIdian and is designed to fit in standard radiotherapy vaults replacing X-ray guided linear accelerators.

Learn more about the system at the ESTRO 36 conference, May 5-9.
