Dual-Energy CT for more accurate stopping power prediction & Importance of range verification

Direct dual-energy CT based stopping power prediction (DirectSPR) allows the reduction of the currently clinical used range uncertainty. The clinical benefits of DirectSPR, its extensive validation and implementation will be presented together with a quantification of the range reduction potential. Furthermore, steps towards in-man validation of the SPR prediction with the IBA Prompt-Gamma-Imaging slit camera will be highlighted.
