IBA Dosimetry Radiation Product StarTrack & myQA Machines

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, dosimetry measurements are integrated with all other QA checks. This enables you to verify and easily reference your daily or monthly QA data with 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
End Benefit


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 behavior, MLC check, light field radiation field congruence, and output checks for photon & electron beams. Energy constancy checks for photon & electron beams are possible with the optional build-up plate (see item BS71-000).

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