MR-Compliant, Daily Beam Quality Measurement
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 4 beam quality checks — energy, output, transverse, and axial symmetry. For flattening filter free (FFF) beams, shape constancy and field size shift are added for a total of 6. 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.
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.

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. The Power and Data Interface (PDI) power supply, power cord, and USB connector are not MRI Safe and must be kept outside of the treatment room.
