Dual Photon Imaging

Chapter

Abstract

When transmission attenuation correction is available, a blank scan should be performed. This will form the baseline for attenuation correction but will also reveal transmission source problems and, in a dedicated system, defective detector blocks (Buchert et al. 1999).
