Line profiles drawn in a transverse slice through both attenuation corrected and non-attenuation corrected cylinder images. In addition to the expected non-uniformity in the non-attenuation corrected image, non-uniformity was also observed in the attenuation corrected image. A 10% reduction in reconstructed signal intensity was observed at the center compared to the edge of the phantom. Data acquired in 2D on the Discovery RX.
