Steffen, Christian Furth, Markus Thormann, David Loewenthal, Jens Ricke, Holger AmthauerCNR of four different sensitometry samples of head geometry (Catphan® phantom, top row A-D) and of the body geometry (Catphan® phantom with additional annulus, bottom row, E-H) for FBP and ASIR reconstructions. The CNRs were examined for Teflon (A, E), Acrylic (B, F), LDPE (C, G), and air (D, H). Due to the definition of the CNR, the slopes of LDPE and air are negative.
