PPT-Material Decomposition using Dual-Energy X-ray of the nView System

Team Member Cong Gao cgao11jhuedu Mentors Mathias Unberath Mehran Armand Russ Taylor Background Dualenergy Xray can help Combine two radiographs acquired at two distinct energies which permits to obtain both density and atomic number.

LEARNING OBJECTIVES. Stable and Unstable Substances. Stable in Chemistry means . unreactive. in the conditions stated.. Unstable means reactive in the conditions stated.. . Thermal Decomposition. When 2 elements combine to form a compound, the product requires heat energy for the elements to be reformed..
