X-ray imaging system and method based on grating phase contrast and photon counting

摘要: The invention discloses an X-ray imaging system and method based on grating phase contrast photon counting. X-rays become coherent after being shaped through a light source grating; the containing changes penetrating samples form beam-split of are converted into intensity pass analyzing counting detector is used for recording information with different intensities; sectional images obtained three-dimensional reconstruction system; finally, components interior fine structure soft tissue obtained. can be detecting in pathology department, radiology department scientific research hospital, early lesion such as small lesions found easily, detection rate greatly increased.
