Patent ID: 10267752

Abstract:
The present disclosure relates to X-ray imaging systems and methods. An exemplary system may comprise a distributed X-ray source arrangement, a fixed grating module, an X-ray detecting device, and a computer workstation. In one illustrative implementation, X-ray sources of the distributed incoherent X-ray source arrangement may sequentially generate and emit X-rays to an object to be detected. Further, for each exposure, the X-ray detecting device may receive the X-rays, wherein after a series of stepping exposures and corresponding data acquisitions, at each pixel of the X-ray detecting device, X-ray intensities are represented as an intensity curve; the intensity curve may be compared to an intensity curve in the absence of the object to be detected, and a pixel value at each pixel may be obtained from a variation of the intensity curves; and image information of the object to be detected may be obtained according to such pixel values.
