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...
Diagnostic medical physicists are often tasked with estimating effective dose (ED) for patient imaging procedures. As chest radiography is frequently performed in children, it is useful to know the general magnitudes of ED for various pediatric ages. The purp...
This session provides a practical framework for optimizing radiography through physics, quality control, and clinical integration. Topics include the physics of technique selection (kVp/mAs, attenuation, filtration, grids, geometry, and detector metrics), ret...
