Systems and Methods of Automated Dose Control in X-ray Imaging

摘要

X-ray imaging systems and methods for exposure control in three-dimensional X-ray imaging include acquiring at least one image with an X-ray emitter and an X-ray receiver. At least one physical characteristic of the object to be imaged is determined from the at least one image. At least one exposure parameter value based is determined based upon the at least one physical characteristic of the object to be imaged. The X-ray emitter and X-ray receiver acquire a plurality of projection images about the object to be imaged using at least one exposure parameter value. A three-dimensional X-ray image is reconstructed from the plurality of projection images.

1. A method of dose control in three-dimensional X-ray imaging, the method comprising:
acquiring at least one image of an object with an X-ray emitter and an X-ray receiver; determining with at least one computer processor at least one physical characteristic of the object from the at least one image; determining with the at least one computer processor at least one imaging parameter value based upon the at least one physical characteristic of the object; acquiring with the X-ray emitter and X-ray receiver a plurality of projection images of the object using at least one imaging parameter value; and reconstructing with the at least one computer processor a three-dimensional X-ray image from the plurality of projection images.
