Effects of inaccurate scatter. a Sinograms showing the scatter estimates obtained with the SSS algorithm and corresponding to the uncorrected, xMLAA-based, and CTAC-based attenuation maps in case of the HP experiment. The bottom row gives the relative difference to the CTAC-based scatter estimate. b Sinograms showing the scatter estimates obtained with the SSS algorithm and corresponding to the uncorrected, xMLAA-based, and CTAC-based attenuation maps in case of the RF experiment.
