Description / Abstract:

This Standards Publication establishes definitions, quantitative measurements of performance characteristics, and reporting techniques for the specification of the following Gamma camera parameters:

a) Intrinsic Spatial Resolution

b) Intrinsic Spatial Linearity

c) Intrinsic Energy Resolution

d) Intrinsic Flood Field Uniformity

e) Multiple Window Spatial Registration

f) Intrinsic Count Rate Performance in Air

g) Intrinsic Spatial Resolution at 75 kcps

h) Intrinsic Flood Field Uniformity at 75 kcps

i) System Spatial Resolution without Scatter

j) System Spatial Resolution with Scatter

k) System Planar Sensitivity and Collimator Penetration and Scatter

l) Detector Shielding

m) System Count Rate Performance with Scatter

n) System Alignment

o) SPECT Reconstructed Spatial Resolution without Scatter

p) SPECT Reconstructed Spatial Resolution with Scatter

q) System Volume Sensitivity

r) Detector-Detector Sensitivity Variation

s) Whole-body System Spatial Resolution without Scatter

The following types of medical radionuclide imaging instruments are included in this standard:

a) Single detector, single crystal planar Gamma cameras

b) Single detector, single crystal tomographic Gamma cameras

c) Multiple detector planar and tomographic Gamma cameras

d) Whole-body Gamma camera devices

e) Discrete pixel detector Gamma cameras

The following types of medical radionuclide imaging instruments are not included in this standard:

a) Coincidence imaging Gamma cameras or systems (these are covered by NEMA NU 2-2012, "Performance Measurements of Positron Emission Tomographs").

b) All medical radionuclide imaging devices not included above
