[Methods for monitoring the integral nonuniformity of the response of a gamma-camera detector].
The paper is concerned with methods of monitoring of integral inhomogeneity (II) used in standards of international organizations and in recommendations of the IAAE. Quantitative analysis of errors at different stages of measurement and processing was performed. Statistical effects were investigated on a mathematical model of an absolutely homogeneous detector. The precision of theoretical calculations was confirmed by experimental testing. Nomograms and their description by simplified formulas with account of such errors in II determination were presented by the authors. They proposed methods for calculation of a 95% confidence interval for an II value of a response of a gamma-camera detector, and issued recommendations for testing computerized gamma-cameras without corresponding special programs of processing.
