scope:

The philosophy and rationale of the standards measurements, and illustrative examples of the analysis and results, are presented in

Journal of Nuclear Medicine, vol. 43, no. 10, 2002. Daube-Witherspoon ME, Karp JS, Casey ME, DiFilippo FP, Hines H, Meuhllehner G, Simcic V, Stearns CW, Adam L-E, Kohlmyer S and Sossi V. "PET Performance Measurements Using the NEMA NU 2-2001 Standard." pp. 1398-1409.

The standards committee has attempted to specify methods that can be performed on all currently available positron emission tomographs. These include single and multiple slice, discrete and continuous detector, time-of-flight instruments, multi-planar and volume reconstruction models, and dedicated positron emission tomographs as well as other coincidence-capable imaging systems. Wherever possible, future developments that could be readily anticipated were taken into account. The committee has not specified methods that may be particularly appropriate for evaluating time-of-flight instruments, pending further evaluation of those instruments by the clinical and scientific communities.
