QA CrossChecker

Comprehensive Beam Verification and Analysis

Comprehensive Beam Verification and Analysis

QA CrossChecker provides the perfect solution for beam and machine verification—without the hassle of large phantoms. Coupled with powerful software, the QA CrossChecker is accurate to within 0.5% of a traditional water phantom, making it the easiest way to verify beam output.

Real time beam steering measurements for linac tuning during acceptance after service.

Comprehensive linac diagnostics from constancy to energy dose verification and modulated field testing, such as electronic wedges.

Features & Benefits

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

QA CrossChecker automatically compares energy measurements with their corresponding reference values. Test reports are created according to user-defined tolerances, and include reference values, allowing you to easily identify changes in your machine.
