Filters in 2D and 3D Cardiac SPECT Image Processing
Figure 6
3D reconstruction at stress (a) and rest (b), by OSEM iterative reconstruction (10 subsets), Butterworth filter (cutoff 0.4 Hz, power 10, Chang AC coefficient 0.1) obtained by the GE. Volumetrix software (GE. Xeleris-2 processing system). The colour scale indicates a high perfusion in white and red regions and a lower perfusion in the other regions. Defected areas are seen on the above image with a darker colour. A perfusion recovery of the defects on the rest images is observed. Data acquired by GE Starcam 4000 and reconstructed in Radiation Physics Unit, University Aretaieio hospital, Athens, Greece, 2013.
