MapCHECK®3
The Benchmark for 2D IMRT QA
MapCHECK®3 is the gold standard for IMRT QA requiring large field measurements.
It offers the highest detector density, highest sensitivity, and largest field size of 2D arrays. Plus, it’s uniquely TG 218-compliant.
Built for Pre-Treatment IMRT QA
SunPoint® 2 Diode Detectors placed uniformly throughout the array offer high sensitivity and proven stability in a large active field size (26 cm x 32 cm). A real-time electrometer measures every pulse with 50-millisecond updates.
Easy Comparison Features
Simply import the QA files from your TPS, and let SNC Patient™ software compare dose distribution from the plan file to actual measured values. Measured points outside of acceptance criteria are highlighted for high and low dose.
