A Novel and Reliable Pixel Response Correction Method (DAC-Shifting) for Spectral Photon-Counting CT Imaging.

This resulted in less overlap between the 95% data ranges of the lower iodine concentrations, as can be appreciated from the linear relationships depicted in Figure 20 , which is a comparison of R 2 values, demonstrating the highly significant difference ( p < 0.001) between the methods without DAC-shifting and with DAC-shifting. 4.
