CT Ion Chamber 10 cm
Ionization Chamber for CTDI Measurements
The DCT10 is a rugged, cylindrical pencil shaped air ionization chamber for CTDI measurements. The CT chamber is intended for measuring and monitoring the exposure output level of CT scanners in a phantom or in air. CT dose index, CTDI, can be measured in accordance with IEC 61223-2-6.
The DCT10 RS can be connected directly to the Barracuda (via an electrometer module supporting bias) to measure CTDI.

How-to: CTDI Measurement with Ion Chamber and Black Piranha
This instructional video will show you how to make a CTDI measurement using CT Ion Chamber and the Black Piranha.
The Black Piranha with accessories makes X-ray QA easy and fast. Connection is automatic – just plug n play. The Quick Check feature identifies the probes you insert and selects the optimum Piranha settings for your measurements – sit back and let the Piranha do the work!
The Cobia Flex is just as easy as the Cobia Smart but with more possibilities. The Cobia Flex has an internal detector, offers ability to connect different probes and ion chambers, and has built in mAs. The measured values can be read directly from the large and clear display, and stored in the Cobia Flex to read later.
Cobia Sense is dedicated for use with an external detector such as RTI Dose Probe, Light Probe, CT ion chamber or external mAs probes. The measured values can be read directly from the large and clear display, and are stored in the Cobia Sense for later viewing.
You need accurate results you can depend on, with maximum precision, and you need them fast. Get accurate and repeatable measurements with the new LoniMover™. It is so easy to use you will reduce scanner down-time too.
