The MRIdian® Linac system is the world’s first FDA cleared system that integrates real-time MR imaging, linac based radiation therapy delivery and intelligent software automation. MRIdian Linac can provide continuous soft-tissue imaging during linac based radiation treatment. Being able to constantly see both the tumor and surrounding organs means you can accurately align the tumor to the treatment beams, adapt or reshape the treatment volume to accommodate changes in the shape and location of the tumor and healthy tissues, and track soft tissues in real time to avoid missing a moving tumor or irradiating sensitive internal structures.

The MRIdian Linac system includes:

A rotating gantry assembly that a houses a compact inline S-band 6 MV standing wave linac with side-coupled cavities
RayZR 138-leaf Double-Focused Double Stacked Multi-Leaf Collimator (MLC) system for reduced penumbra and minimum interleaf leakage and sharpest POSSIBLE beams capable of delivering high-dose stereotactic radiosurgery (SRS)
Patented magnetic and RF shielding technology that isolates the workings of the linac and the MRI system from each other
A 0.35 T split magnet designed for unrestricted beam path, volumetric and multi-planar soft tissue imaging
A patient couch with 3 degrees of freedom, two in-room couch control panels and a laser positioning system to facilitate initial patient setup
A control console, located just outside the treatment room, to start and stop treatment and monitor status
An operator console for MRI acquisition, patient positioning, dose prediction, re-optimization and real-time tumor tracking
Integrated treatment planning and delivery software for creating treatment plans and managing the treatment delivery process
A planning station for defining structures and constraints and planning and re-optimizing treatments with support for conducting plan reviews in a remote manner
A database server containing patient and machine data used by the system
