Embodiment Construction

[0110] The inventive subject matter described herein includes systems and methods for inspecting images of objects using x-ray beams having polychromatic energy distributions. In particular, the subject matter described herein discloses improved DEI and DEI systems and related methods for detecting images of objects. According to one aspect, the inventive subject matter described herein can include a method for detecting an image of an object. The method may include generating a first x-ray beam having a polychromatic energy distribution. Also, the method may include positioning the monochromator crystal at a predetermined position to directly intercept the first X-ray beam to generate a second X-ray beam having a predetermined energy level. Also, the object may be positioned in the path of the second X-ray beam such that the second X-ray beam is transmitted through the object and emitted as a transmitted X-ray beam via the object. The transmitted x-ray beam can be directed ...

Abstract

Systems and methods for detecting an image of an object using an X-ray beam having a polychromatic energy distribution are disclosed. According to one aspect, a method can include detecting an image of an object. The method can include generating a first X-ray beam having a polychromatic energy distribution. Further, the method can include positioning a single monochromator crystal in a predetermined position to directly intercept the first X-ray beam such that a second X-ray beam having a predetermined energy level is produced. Further, an object can be positioned in the path of the second X-ray beam for transmission of the second X-ray beam through the object and emission from the object as a transmitted X-ray beam. The transmitted X-ray beam can be directed at an angle of incidence upon a crystal analyzer. Further, an image of the object can be detected from a beam diffracted from the analyzer crystal.

Description

[0001] related application [0002] This nonprovisional patent application claims U.S. Provisional Application No. 60 / 761,796 filed January 24, 2006, U.S. Provisional Application No. 60 / 761,797 filed January 24, 2006, and U.S. Provisional Application No. 60 / 761,797 filed July 6, 2006. Priority to Application No. 60 / 819,019, the entire contents of which are hereby incorporated by reference. technical field [0003] The inventive subject matter disclosed herein relates to X-ray imaging. More specifically, the inventive subject matter disclosed herein relates to systems and methods for detecting images of objects by using an x-ray beam having a polychromatic distribution. Background technique [0004] X-ray imaging has been used in various fields of object imaging. For example, X-ray imaging has been widely used in the medical field of non-destructive testing and X-ray computed tomography (CT). Various other types of technologies are also being used in medical imaging. An o...
