Piranha Mammo

All you need to take QA measurements for any 2D or 3D X-ray system in hospitals or mammography clinics.

The ideal instrument for Mammo QA testing

Piranha Mammo is the ultimate solution designed by experts for anyone working with specialist diagnostic X-ray technology in hospitals or mammography clinics. It measures kVp, time, HVL, Dose, Dose rate, and presents Waveforms.

You get extremely accurate measurements that you can then use for your in-depth analyses. All the measurements are transmitted wireless to your Ocean software for analysis, storage, and reports in one smooth process.

With Piranha Mammo you have a compact solution for fast and reliable testing. You can be sure of extremely accurate measurements that can be used for in-depth analysis.

Ocean software – quick and repeatable

Its compatibility with the Ocean diagnostic software provides quick and repeatable QA work. Ocean can perform instant real-time analysis during your measurements. Use your tablet/laptop as both an interactive display during the measurements and as a powerful analysis tool when you are back at the office.

All your measurements, along with the result and the report, will be stored inside your tablet or laptop; there is no unnecessary, time-consuming data transfer.

A complete QA solution instantly

The Piranha Mammo comes ready-to-use with everything you need included. It is really an all-in-one multifunction meter. Connect to your computer wireless or via USB and you have a complete QA system!

Position check

The unique feature of the Piranha Mammo 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.
