Piranha CT

Fast and accurate CT dose measurements

The Piranha CT X-ray QA meter measures and presents all parameters instantly and simultaneously. It measures kVp, Time, Total Filtration, CTDI parameters, dose length product, and presents Waveform.

Several important parameters can also be measured such as CTDI100, CTDIw, CTDIvol, DLP, FWHM, Geometric efficiency, and tube current variations. Choose your Piranha CT with CT Dose Profiler or Ion chamber.

A complete QA solution

The Piranha CT X-ray meter comes ready to use with everything you need.  It is really an all-in-one multifunction meter. Connect to your computer wireless or via USB for a complete QA system.

Position Check feature

The unique feature of the Piranha CT X-ray meter makes it possible to check the position of the detector before measuring. By using the Position Check function, you can verify that the detector area is fully irradiated. Possible field inhomogeneities are also neutralized.

CT dose profiles

Use with RTI’s Chamber Adapter, Ion Chamber, and CT Dose Profiler for deep analysis of CT dose profiles.
