Reducing Loss of Image Quality Because of the Attenuation Artifact in Uncorrected PET Whole-Body Images

In whole-body PET, it is not unusual to shorten the study time by omitting the transmission scan and to ignore attenuation during reconstruction. If a transmission scan is available, many centers reconstruct the images with, but also without, attenuation correction. Although ignoring attenuation lea...
