Daily QA™-MR is the first commercially available daily QA device for MR-linacs. It enables fast beam quality checks in the presence of magnetic fields.

With Daily QA-MR, a single beam measurement supports 3 beam quality checks — output, transverse, and axial symmetry. Compare results to baseline values in the software to determine if intervention is needed before treating patients.

The Daily QA-MR and associated cabling, stand, and accessories are MR-compliant, as specified in ASTM F2052-15 for field strengths up to 1.5 T.

Trusted Design
Daily QA-MR is built upon the Daily QA™ 3 gold-standard design, now reconfigured to support MR environments. Tests support rotational and FFF beams, with no warm-up or pre-irradiation required for testing.

Quick Start Features

No additional buildup, flipping, or pre-irradiation necessary for use.

Calibration Fixture

A calibration fixture is included with every Daily QA-MR for device calibration. Daily QA-MR will interface with a standard lok-bar on the MR-linac couch for accurate, reproducible daily positioning.

Temperature & Pressure Correction

Automated corrections eliminate the need to measure and manually enter these values into the software.

Accelerate your MR-linac morning QA.

MR Compatibility

The Daily QA-MR and its associated cabling, stand, and accessories do not contain ferromagnetic material in amounts that would result in magnetically induced displacement forces that exceed those specified in ASTM F2052-15 for field strengths up to 1.5 T.
