To provide a quantitative understanding for the interdependence of radiopharmaceutical uptake, detector efficiency, and reconstruction parameters on SPECT statistical accuracy, a unified approach to estimating %rms noise has been developed. The procedure consists of the following steps: 1) Determine an acceptable geometric model for the organ system including radionuclide concentration Qs. 2) Select desired transverse and axial resolutions. 3) Select an acceptable imaging time Tscan. 4) Compute the total number Nt of expected gamma photons in slice using: Copyright © 1985 by The Institute of Electrical and Electronics Engineers, Inc.
