Monte Carlo simulations are widely used to derive effective dose conversion factors (k-factors) for CT; however, acquisition parameters such as helical pitch and tube starting angle are often randomly selected. The impact of these parameters on the variabilit...

High-pitch dual-source acquisition (“FLASH”) with tin spectral filtration has substantially reduced radiation dose while minimizing patient motion, both of which are particularly important for pediatric imaging. However, in adults, tin-filtered spectra have b...
