QA BeamChecker™ Plus

Save time with fewer trips in and out of the vault, automatic energy detection, quick measurements and customizable QA interface - no cables and no PC required. Perform routine daily QA measurements for traditional linear accelerators and rotational VMAT systems including those from Varian, Elekta, and Accuray.

QA BeamChecker™ Plus part of complete solution for: Daily QA CyberKnife

QA BeamChecker™ Plus Overview

Automatic Energy Detection

  • Measure energies in any order and automatically detect energy type, begin measurement, apply corrections and display results.
  • Data is automatically saved and the device readies itself for the next energy within 10 seconds for the fastest QA on the market.

Software-Free Operation

  • Does not need to be controlled via PC, allowing for immediate pass/fail results.
  • No cables, no wires, no hassles.
  • Download data later allowing for easy trending and reporting.
