X-Ray Interactions vs Body Tissues vs Energy
Graph Showing the Relative Predominance of photoelectric and Compton interactions in various tissues at increasing levels of kVp. While Compton interactions occur in much greater numbers in substances with higher atomic numbers such as bone and iodine; however, they still drop quickly as kVp increases.
