CT ionization chamber

    The cylindrical pen CT ionization chamber can be used to measure the dose length product parameters of CT machine with CT dose motifs.

    The length of the ionization chamber is 10cm, and there is a good consistent response in the whole measurement length. Typical measurements are CTDI1 and CTDIW2, that is, dose length product, which meets the requirements of IEC 61223-2-6.
