QA CrossChecker™ Overview
Optimized Detector Positioning For Key Linac QA Routine
- 453 air-vented pixel ionization chambers with optimized 5 mm spacing allows for accurate machine QA including dosimetric, mechanical, gating and MLC performance testing.
- Parallel readout from independent electrometers allows for fast measurements.
Water Phantom Free
- Compare results to water phantom baselines and achieve accuracy within 0.5%.
- Perform accurate monthly machine QA without the hassle of a water phantom.
Pair With Software For Lightning Fast Reports
- Automatically compare energy measurements with their corresponding reference values.
- Test reports are created according to user-defined tolerances.
- Reports include reference values, allowing you to easily identify changes in your machine.
