Patient QA SolutionsMore than 50 ArcCHECK-MR devices are already in use clinically around the world. ArcCHECK-MR builds confidence with every treatment for the rapidly growing MR focus in cancer care.
MR-Ready
The ArcCHECK-MR and associated cabling, stand, and accessories are MR-compliant for field strengths up to 1.5T, as specified in ASTM F2052-15.
Fully Independent
At the heart of the ArcCHECK-MR are more than 1,300 SunPoint® Diode Detectors providing consistent and highly sensitive measurements for all gantry angles. Independent absolute dose measurements enable the gold standard for patient plan and machine QA testing.
Highly Efficient
Simply connect the single cable, then start to measure. No background measurements, no warm-up, no separate inclinometers, and no additional hardware are required.
Ramping up your MRgRT program?
“The complexity of online adaptation necessitates not only thorough commissioning but the establishment of on-going comprehensive quality assurance for each fraction that includes not only a phantom-less QA but also a method to ensure that all other components of the plan are accounted for and checked.”
