ESTIMATING SPECT COUNT DENSITIES, SCATTER FRACTIONS, AND STATISTICAL NOISE.
To provide a quantitative understanding for the interdependence of radiopharmaceutical uptake, detector efficiency, and reconstruction parameters on SPECT (single photon emission computed tomography) statistical accuracy, a unified approach to estimating %rms noise has been developed. The results indicate that the mathematical model is useful in evaluating SPECT performance, providing guidance in the selection of acquisition and reconstruction parameters, improving SPECT quantification, and estimating the usefulness of proposed SPECT radiopharmaceuticals.
