Investigation of Attenuation Correction for Small-Animal Single Photon Emission Computed Tomography
Figure 6
The images of the concentric phantom acquired after corrections. (a) Scatter correction, (b) Chang’s method in combination with scatter correction, (c) CTAC in combination with scatter correction, (d) CTIACR in combination with scatter correction, and (e) CTMAC in combination with scatter correction. The line profiles through the center of the concentric phantom are shown, and the purple lines are the true activity concentrations obtained from measurements.
