MATERIAL DIFFERENTIATION WITH PHASE CONTRAST IMAGING |
摘要 |
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. |

1. A method of determining material composition of an object, the method comprising:
capturing a series of digital radiographic images of the object using an x-ray beam having a single average energy magnitude; determining an intensity of the captured images of the object; determining a phase shift magnitude that occurred in the object; and determining a difference in material composition of the object based on a combination of the determined intensity and the determined phase shift of the captured images. |
