• Active Detector area: 0.8 mm x 0.8 mm (0.64mm²)  
  MapCHECK Overlay
• Inner Array: 10 x 10 cm array: 7.07 mm diagonal, 1.0cm horizontal/vertical
• Outer Array: 6 cm wide: 14.14 mm diagonal, 2.0cm horizontal/vertical
• Axial and Transverse (X,Y) linear array length: 22 cm, 1.0 cm detector spacing
• Diagonals linear array length: 25.4 cm, 7.07 mm detector spacing
• User calibrated every 1-2 years using a patented calibration method

Applications

• Dose plan verification (field by field, composite or rotational/arc)
• MLC QA; Small detectors identify MLC misalignments as fine as 0.2mm
• Beam QA (routine flatness, symmetry, output measurements)
• Gating QA (with MotionSim XY/4D option)
• Dose based EPID IMRT QA (with EPIDose option)

Setup

• Easy and quick setup
• Single power/data cable that is common to other Sun Nuclear instruments
• Option of using Isocentric Mounting Fixture (IMF™) for measurement at prescription angle
