Essential Specifications
Absolute dose measured at 445 detector locations with 221 detectors in the critical 10 x 10cm field center – the highest detector density of any 2D array. MapCHECK detectors are only 0.64mm2, over 25 times smaller than ion chambers and more capable of measuring complex dose gradients.
- X & Y axes 22 cm each, 1.0 cm detector spacing
- Diagonals 25.4 cm each, 7.1 mm detector spacing
- No frequent recalibration necessary
- User calibrated 1-2 years via patented method
Powerful Applications
MapCHECK was designed specifically for challenging IMRT plan verification. Dynamic & static MLC delivery is supported, as well as field by field and composite analysis. Additional applications are:
- MLC QA: identify MLC errors as fine as 0.2mm
- Beam QA: routine flatness, symmetry, output measurements
- Rotational Dosimetry
- Gating QA
- EPID based IMRT QA
- MU Calculations
- EBT & Processor based film QA
Fastest Setup
MapCHECK sets up in mere seconds, and requires no warm up time. Simply connect Sun Nuclear’s standard cable and launch the software. Connection to the PC is via USB, so no separate IP address is required.
- Connect to gantry with optional Isocentric Mounting Fixture (IMF™)
- QA takes just slightly longer than the time needed to deliver the plan
Most Advanced Software
MapCHECK software is based on over 5 years of user feedback, the most of any 2D array. Simple 2 button operation (Start, Compare) is very efficient, and all data and analysis is immediately available on the executive dashboard. Additional options include:
- Change analysis criteria instantly: % Difference, DTA, Gamma
- Filter patient analysis by target & critical structures
- Profiles, Histograms, MLC Wizard, Combine & Merge Feature, Calculate Best Fit, Film Scanning, Print to PDF, and much more…
