    One Shot HVL for Mammography

    07 May 12 One shot HVL for mammography is now available to all new Piranhas of version 2 or higher.
    One shot HVL is possible both if you are using Ocean or QA Browser, with or without compression paddle.

    All Piranhas (version 2 or higher), which are in for re-calibration, will get the one shot HVL feature.

Chamber Adapter

Magna 1 cc

Magna 1 cc

Designed Especially for Mammographic Measurements

The Magna 1cc ionisation chamber is designed especially for mammographic dose and dose rate measurements. However, it has an excellent energy response and can also be used for radiographic applications. The Magna Ion Chamber is the ideal choice for two reasons;
Evaluations of Magna chambers show an average response is within ± 1% over an extended mammography range of 20-40 kVp (HVL of 0.15 mm to 0.73 mm Al).
All mammographic mean glandular dose tables are based on in air measurements. MAGNA’s air equivalent construction makes it ideally suited for in air exposure measurements of mean glandular dose. The Magna 1 cc will be delivered in a durable case for its best protection.

Magna 1cc and Piranha

The Magna 1cc can be connected via Chamber Adapter to the Piranha to measure Mammo applications.

Magna 1cc together with Barracuda

The Magna 1cc can be connected directly to the Barracuda (via a bias electrometer module EMM-Bias module). It can be used especially for mammography applications when an ion chamber is preferred instead of a solid-state detector.

Magna 1cc together with Solidose 400

Magna 1cc can also be connected directly to the Solidose 400 - no adapter cable is needed. It can be used especially for mammography applications when an ion chamber is preferred instead of a solid-state detector.
