Abstract
A phase contrast x-ray imaging system generates an absorption image and a phase shift image of an object under study. The absorption image represents a measurement of the imaged object's attenuation of radiographic energy, and the phase shift image represents a measurement of the imaged object's phase shifting of the radiographic waves passing through the object. The two images may be used to improve soft tissue discrimination in radiographic imaging.
Claims16
A method comprising:
- radiographically scanning an object using a PCI imaging system;
- and
- generating a plurality of radiographic images in response to the step of scanning, including generating a first image of the object that represents levels of absorption of radiographic radiation by the object and generating a second image that represents phase shifts of the radiographic radiation caused by the object.
A phase contrast imaging system comprising:
- a radiographic energy source;
- and
- a flat panel digital detector,
- wherein the source and detector are configured to radiographically expose an object to produce a plurality of images of the exposed object, and
- wherein a first one of the produced images comprises image data representing the object's attenuation of the radiographic energy and a second one of the produced images comprises image data representing a phase shift of the radiographic energy passing through the object.
