Features a set of two nested homogenous cylinders designed to simulate an adult head and body. Used primarily for Computed Tomography Dose Index (CTDI) measurement and to separate dose information for each. When performing dose profile measurements, dose phantoms allow to collect information for the maximum, minimum and mid-range values of the nominal tomographic section thickness. The two parts are frosted with white lines to simplify the alignment at setup. It is delivered in a wheel carried, heavy duty Storm Case with additional space for an X2 Base unit, X2 CT detector and X2 R/F detector.
