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 free-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.
