CTDI Phantom sets | Specifications The CTDI Phantom sets are designed to facilitate quality assurance testing of computed tomography (CT) systems. These sets simulate the head and body of both adult and pediatric patients, and are constructed from two or three nested PMMA cylinders. The phantom cylinders are intended for measurements of the CT dose index (CTDI) and the dose profile of the CT system. Included in each set are PMMA pegs and a positioning sponge for each phantom cylinder, which enable accurate placement of the phantom within the CT scanner. The sets also come with a hard case that features a built-in trolley for convenient storage and transportation. Overall, the CTDI Phantom sets offer a reliable and effective solution for evaluating the performance of CT systems. Three parts kit: 10, 16 and 32 cm diameter. Both the RTI CT Ion Chamber, Art.
