Method for detecting an image of an object
First Claim
1. In a method for detecting an image of an object, wherein an x-ray beam is generated, the improvement comprising:
- transmitting the x-ray beam through the object and emitting from the object a transmitted beam;
directing the transmitted beam at an angle of incidence upon a crystal analyzer;
detecting a first image of the object from a diffracted beam emitted from the crystal analyzer at a low rocking curve angle setting of the crystal analyzer;
detecting a second image of the object from a diffracted beam emitted from the crystal analyzer at a high rocking curve angle setting of the crystal analyzer; and
combining the first image and the second image to derive a refraction image and an absolute absorption image of the object.

Abstract
A method for detecting an absorption, refraction and scatter image of an object by independently analyzing, detecting, digitizing, and combining images acquired on a high and a low angle side of a rocking curve of a crystal analyzer. An x-ray beam which is generated by any suitable conventional apparatus can be irradiated upon either a Bragg type crystal analyzer or a Laue type crystal analyzer. Images of the absorption, refraction and scattering effects are detected, such as on an image plate, and then digitized. The digitized images are simultaneously solved, preferably on a pixel-by-pixel basis, to derive a combined visual image which has dramatically improved contrast and spatial resolution over an image acquired through conventional radiology methods.
