MapCHECK® 3
The New Benchmark for 2D IMRT QA
- 1,527 SunPoint® 2 Diode Detectors
- Highest detector density
- Largest active field size
The MapCHECK family is the world's most selected independent 2D measurement array, setting the standard for modern, efficient and stringent QA. Building upon this legacy, with MapCHECK 3 we've continued to innovate by reducing the effects of volume averaging while providing high resolution 2D measurements.
MapCHECK 3 is the next evolution in the MapCHECK family--the world's most chosen 2D array.
MapCHECK 3 provides the highest detector density, smallest detector size, and largest field size of any 2D array for IMRT QA. Over 1,527 SunPoint® 2 Diode Detectors measure only 0.48 mm each, and measure up to a 26 x 32cm field. SNC Patient™ software allows rapid analysis of QA measurements against plan.
Patient Plan QA
Stringent, fully independent measurement QA of patient plan and delivery with SNC Patient software.
Simply import the QA files from your treatment planning system (TPS) and SNC Patient software compares the dose distribution of the treatment plan file to the actual measured values. Measured points that do not fit within the acceptance criteria are highlighted in red for high dose and blue for low dose.
A water equivalent phantom that adapts any MapCHECK 3 for RapidArc®, VMAT, and TomoTherapy®. Setup time is fast and measurement may occur in coronal and sagittal orientations.
