Material differentiation with phase contrast imaging

A method and system to determine material composition of an object comprises capturing a series of digital radiographic images of the object using a single exposure energy level. An intensity of the captured images is determined as well as phase shift differences. A difference in material compositio...

Zusammenfassung:	A method and system to determine material composition of an object comprises capturing a series of digital radiographic images of the object using a single exposure energy level. An intensity of the captured images is determined as well as phase shift differences. A difference in material composition of the object may be determined based on a combination of the determined intensity and the modulated phase shifts of the captured images.
