Pre-treatment patient QA
ArcCHECK and MapCHECK for Patient QA in Radiotherapy
ArcCHECK and MapCHECK 3 answer different pre-treatment QA needs. The right choice depends on clinical technique, measurement geometry, analysis depth and how the system fits the department workflow.
Where each solution fits
ArcCHECK
ArcCHECK is built for 3D pre-treatment QA when rotational delivery, absolute dose and patient-volume measurement are central to the decision.
MapCHECK 3
MapCHECK 3 is built for IMRT QA with a 2D diode array, a wide active field and fast comparison between planned and measured dose distributions.
