ABSTRACT

Performance measurements of scintillation cameras are made (a) by the manufacturer to test and specify the equipment he sells, (b) by the customer as part of his acceptance testing, and (c) by the user as part of a periodic quality-control program. This paper describes the NEMA (National Electrical Manufacturer's Association) standard, which was developed to provide a uniform criterion for the measurement and reporting of performance parameters for scintillation cameras, and by which a manufacturer may specify his device. The purpose of this paper is to familiarize the nuclear medicine practitioner with the standard, the measurement methods, the reasons for them, and the meaning of the reported values.
