Pro-NM PETsensi

The PET sensitivity phantom is used to measure the sensitivity or ability of positron emission tomographs to detect positrons. The phantom used for this purpose is a set of five metal tubes with a similar wall thickness. A plastic tube homogeneously filled with 18F liquid is inserted for the measurement. Successive measurements are made by accumulating the sleeve wall thickness with the uniform line source surrounded by known absorbers. From these measurements, the sensitivity without absorbers can be extrapolated to arrive at an attenuation free measurement. The measurement setup, data collection and analysis are described in section 5 of the NEMA standard NU 2-2007.
