INVESTIGATION OF THE PERFORMANCE OF THE GENERAL-ELECTRIC ADVANCE POSITRON EMISSION TOMOGRAPH IN 3D MODE

Performance measurements of the General Electric ADVANCE Positron Emis sion Tomograph operating with the septa retracted (3D mode) were made. All reconstructions were performed with the GE ADVANCE 3D package. Pe rformance 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: tran saxial and axial resolution, uniformity, recovery coefficients, count rate performance, dead time accuracy, and effect of scatter correction .
