Acceptance Tests for PET Scanners

Acceptance tests are a battery of quality control tests performed to verify various parameters specified by the manufacturer for a PET scanner. These are essentially carried out soon after a PET scanner is installed in order to establish the compliance of specifications of the device. The most common and important specifications are transverse radial, transverse tangential, and axial resolutions sensitivity scatter fraction and count rate performance, ft is essential to have a standard for performing these tests so that a meaningful comparison of scanners from different manufacturers can be made. 

The spatial resolution of a PET scanner is determined by the FWHM of point-spread-functions (PSF) obtained from measurement of activity distribution from a point source. The spatial resolution can be transverse radial, transverse tangential, and axial, and these values are given in Table 6.1 for scanners from different manufacturers.
