MapCHECK® 3

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 PatientTM 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.

SNC Patient Software

SNC PatientTM 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.

  • 2D patient plan QA
    • Conventional IMRT and 3D conformal
  • 1,527 SunPoint® 2 Diode Detectors uniform throughout the array
    • Smallest detector (0.007 mm3)
    • High sensitivity
    • Less drift
    • No dose volume average
  • Field Size: 26 x 32 cm
  • Real time electrometer measures every pulse with 50 ms updates
  • Includes SNC PatientTM software
    • Compare measured dose to planned dose with a single click
    • Compare relative or absolute dose data using Distance-to-Agreement or Gamma Analysis
  • Quick and reproducible isocentric measurements at any gantry angle with IMF or GMF
  • Single power/data cable
    • Manages all power and data in one connection
  • Integrated electronics
    • Self-contained with no separate electronics to set up
  • Lightweight (5.6 kg)
  • Patented user calibration
    • Clinically proven Wide‑field CalibrationTM is performed on site and does not require disassembly of the MapCHECK device
  • No pre-irradiation or warm-up required for absolute dose measurements
