Abstract

Performance measurements of the General Electric Advance Positron Emission Tomograph operating with the septa retracted (3D mode) have been made. All reconstructions were done with the GE Advance 3D package. Performance tests were carried out with: the NEMA phantoms; a 3D Hoffman phantom; a Data Spectrum torso phantom with lung and cardiac inserts; and the “Utah” 3D evaluation phantom. Data collected included: transaxial and axial resolution, uniformity, recovery coefficients, count rate performance, dead time accuracy, and effect of scatter correction
