StarTrack* is seamlessly integrated into myQA Machines and myQA FastTrack

Attain instant and real-time analysis using the Dosimetry Plug-in for myQA Machines. With myQA you integrate your dosimetry measurements with all your other QA checks. This enables you to verify and reference easily your daily or monthly QA data with your reference data collected during beam commissioning.

Convenient beam constancy verification in one single shot. Simply add the  build-up plates to your StarTrack* detector.

IBA Dosimetry Radiation Product StarTrack


Advanced, pixel ionization chamber based linac QA device with unique detector layout to verify main QA parameters in just one measurement, such as daily, weekly and monthly QA, symmetry, flatness, primary and diagonal axes, field size & penumbra, wedge check, Linac start-up behaviour, MLC check, light field radiation field congruence, output checks for photon & electron beams.By means of an optional build-up plate (see item BS71-000) energy constancy checks for photon & electron beams are possible.

The StarTrack* is easy to setup and align (treatment couch, or optionally, gantry mount). Data transfer to a PC or laptop goes via an Ethernet connection. All necessary cabling is included.
