WebThe RTI CT Ion (Ionization) Chamber is for use with the Piranha meters, Cobia FLEX R/F, or Cobia SENSE. The RTI CT Ion Chambers – 10 cm and 30 cm – are intended for CTDI and dose length product measurements on CT scanners in a phantom or free-in-air. Both chambers can be connected via the RTI Chamber Adapter to the Piranha or to the Cobia. http://resource.npl.co.uk/docs/science_technology/ionising%20radiation/clubs_groups/rsug/081201/posters/kq_factors.pdf
