PET sensitivity phantom is used to measure the sensitivity or ability of positron emission tomographs to detect positrons.

Features and Benefits

• 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.
• Five internally stacked concentric aluminium tubes – all 700 mm in length.
