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.


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 PatientTM 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.
