The Solution for Beam and Machine Verification

Essential tool for comprehensive machine verification and workflow optimization. Quickly perform all of your daily, weekly or monthly checks via seamless, pre-defined queues and protocols.

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.

Fast Reports

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.
