    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 can be connected via Chamber Adapter to the Piranha or Cobia to measure CTDI.

    The DCT10 RS can be connected directly to the Barracuda (via an electrometer module supporting bias) to measure CTDI.
