Features
- Enables users to perform scatter fraction, count loss and random measurements on PET scanners
- Consists of a long polyethylene cylinder with an eccentric line source tube
- Complies with Section 4 of NEMA standard NU2-2001
One purpose of the test procedure based on the PET cylinder phantom is to measure the relative system sensitivity of positron emission tomographs to scattered radiation. Another purpose is to measure the effects of system dead-time and the generation of random events at several levels of source activity. The phantom used for these purposes is a polyethylene cylinder of 700 mm length and 200 mm outside diameter. A plastic tube homogeneously filled with 18F liquid is inserted for the measurement at a distance of 45 mm parallel to the central axis. This line source has an outside diameter of approx. 5 mm and a length of approx. 800 mm. The measurement setup, data collection and analysis are described in Section 4 of the NEMA standard NU2-2001.
