Patient QA SolutionsMapCHECK® 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.
See why MapCHECK 3 is the chosen solution for IMRT QA.
Address Rotational Beams
Use MapCHECK 3 with MapPHAN™, a water equivalent phantom, for RapidArc®, VMAT, and TomoTherapy®. Setup time is fast and measurement can occur in coronal and sagittal orientations.
Quick Start Features
Portable and lightweight array with no warm-up or pre-irradiation necessary for use
Easy Annual Calibration
Patented Wide Field Calibration step-by-step instructions are included in SNC Patient™ software, for a 15-minute annual calibration.
Isocentric Mounting Fixtures
GMF™ and IMF™ Mounting Fixtures mount the MapCHECK 3 to the head of the gantry for quick, reproducible isocentric measurements at any gantry angle.
SNC Patient™ Software
Import QA files from TPS, and SNC Patient compares dose distribution of plan file to actual measured values. Points outside acceptance criteria are clearly highlighted.
