Abstract: 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.

Abstract: A system and method of X-ray imaging includes an X-ray emitter that projects X-rays. An X-ray receiver that receives X-rays from the X-ray emitter to produce a plurality of projection images. A filter with at least one filter leaf absorb at least a portion of the X-rays from the X-ray emitter to define a limited field of view within a full field of view with the X-rays being attenuated in at least one attenuated portion of the full field of view. A processor reconstructs a three dimensional image based upon the projection images of the full field of view. The limited field view is located within the reconstructed three dimensional image. At least one corrective parameter is determined from the reconstructed three dimensional image. A three dimensional image is reconstructed based upon the limited field, of view and the at least one corrective parameter.

Abstract: A method, a device, a system and a computer program are for controlling limited-area computer tomography imaging. The method includes determining location data of a first imaging object when the first imaging object is positioned in an imaging area, determining reference location data related to the first imaging object and adjusting the imaging area based on the location data of the first imaging object and said reference location data for imaging a second imaging object. The first and the second imaging object can be located at a distance determined by the reference location data from each other or symmetrically in relation to the reference location data.

Abstract: 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.
