MapCHECK2 IMRT QA

Building on the success of the original MapCHECK, the MapCHECK 2 offers 1536 diode detectors within a field size of 32 x 26cm - the most of any 2D array available. A larger field size and uniform detector density (7mm detector spacing) means that multiple measurements for Head and Neck, Breast, Lung, and Boost fields are not necessary, saving precious time.

MapCHECK 2 Hardware

Most Detectors - 1536; more than any 2D array and more than triple the number of detectors as the original MapCHECK
Largest Field Size - 32 x 26cm; the largest of any 2D array and more than double the size of the original MapCHECK
Highest Detector Density - 7.07mm uniform distribution across the entire array

A larger field size and higher detector density means that multiple measurements for Head and Neck, Breast, Lung, and Boost fields are a thing of the past, saving precious time.

Patient plan QA requires diodes. Over six years of clinical use in hundreds of user sites and more than 45 publications have proven the superiority of diode detectors for IMRT measurements. These diodes avoid the dose volume averaging problems seen with ion chambers, and because IMRT beams are collections of small fields with steep dose gradients, this is a critical advantage. Our diode detectors offer long term stability, reproducibility, absolute dose measurements, and are only 0.64mm2.

Faster, Easier and More Powerful
Real Time - MapCHECK 2 delivers data in REAL-TIME with updates every 50ms and measures each pulse.

Motion QA - With the optional MotionSim XY/4D table, MapCHECK 2 can mimic a patient specific respiratory trace for accurate and realistic gating and target motion QA.

Calculations - Optional MapCALC software streamlines independent calculations by incorporating independent 2D dose and MU calculations directly into the MapCHECK 2 software.

EPIDs - Optional EPIDose software computes an absolute dose plane using any EPID raw image; allowing independent comparisons of dose, not image, based QA.
