MRIdian is the only radiotherapy solution that can see and track soft tissue and tumors in real time.

MRIdian’s SmartVISION delivers high-definition, diagnostic-quality imaging designed specifically to maintain high-fidelity beam delivery while virtually eliminating the risks of skin toxicities, trapped or distorted dose and other concerns that may occur when high magnetic fields interact with radiation beams.

MRIdian shapes the dose to fit the day. It’s the only MR solution that enables integrated adaptive treatment for on-table reoptimization of the daily treatment plan.

MRIdian captures 8 frames per second, leveraging high-contrast anatomical detail to rapidly reshape dose delivery based on the current position of both the tumor and adjacent critical structures – all while the patient is in the treatment position.

MRIdian knows when to strike, visualizing the tumor’s edges and surrounding organ position in real time.

It’s the only RT solution with automated beam gating for precise and accurate dosing. When the tumor moves, the beam stops. Clinicians can shrink margins with confidence while escalating dose and reducing fractions.
