System and method of artifact correction in 3D imaging

摘要

A system and method of x-ray imaging includes obtaining a plurality of x-ray projection images of a patient. At least one object in the plurality of x-ray projection images is identified. A priori information of the identified at least one object is obtained. A three dimensional volume is reconstructed from the plurality of x-ray projection images. The a priori information is used to refine the acquisition of x-ray projection images or presentation of the three dimensional volume.

1. A method of x-ray imaging, comprising:
obtaining a first plurality of x-ray projection images of a patient; identifying at least one object as at least one identified object in the first plurality of x-ray projection images; obtaining a priori information of the at least one identified object; and adjusting at least one x-ray imaging parameter based upon the at least one identified object and the obtained a priori information; obtaining a second plurality of x-ray projection images according to the at least one adjusted x-ray imaging parameter; reconstructing a three dimensional (3D) volume from the second plurality of x-ray projection images and the a priori information of the at least one identified object to produce a reconstructed 3D image; wherein the at least one identified object comprises a dental implant and the a priori information comprises a shape of the dental implant.
