Abstract

With the expanding use of CT and growing concerns for radiation related risks, several efforts have been made in scientific community to lower radiation dose without compromising the image quality (Berrington de González et al. Arch Intern Med 169:2071–2077, 2009; Schauer and Linton Health Phys 97:1–5, 2009; UNSCEAR Health Phys 79(3):314, 2000). In this chapter, we discuss application of image post processing filters to low radiation dose CT, as one of the technical advances for lowering radiation dose.
