APPARATUS AND METHOD FOR TWO-VIEW TOMOSYNTHESIS IMAGING
First Claim
1. An apparatus for tomosynthesis imaging comprising:
- an x-ray source configured to irradiate an object with a beam of x-rays;
a detector configured to detect the x-ray beam that passes through the object; and
a computer programmed to;
perform a scan, the scan comprising;
a translation of at least one of the x-ray source and the detector along a path;
an acquisition of a tomosynthesis image dataset; and
a reconstruction of one or more three-dimensional (3D) volumes adapted to one or more predetermined view directions, wherein at least one of the one or more predetermined view directions is aligned outside of a central view direction.

Abstract
The invention is a directed to an apparatus for tomosynthesis imaging, wherein the apparatus comprises an x-ray source configured to irradiate an object with a beam of x-rays and a detector configured to detect the x-ray beam that passes through the object. The apparatus further comprises a computer programmed to perform a scan, wherein the scan comprises a translation of at least one of the x-ray source and the detector along a path, an acquisition of a tomosynthesis image dataset, and a reconstruction of one or more three-dimensional (3D) volumes adapted to one or more predetermined view directions, wherein at least one of the one or more predetermined view directions is aligned outside of a central view direction.

15. A method of forming three-dimensional images of an object, the method comprising:
-
irradiating an object with a beam of x-rays at a plurality of positions along a path, wherein the beam of x-rays is emitted from an x-ray source; acquiring a tomosynthesis image dataset based on x-rays detected by an x-ray detector; and reconstructing one or more three-dimensional (3D) volumes from the tomosynthesis image dataset, wherein the reconstructing of the one or more 3D volumes is adapted to one or more predetermined view directions, and wherein at least one of the one or more predetermined view directions is aligned outside of a central view direction. - View Dependent Claims (16, 17, 18, 19, 20)

21. A tomosynthesis imaging system for forming three-dimensional images of an object, the system comprising:
-
an x-ray source configured to irradiate an object with x-rays; an x-ray detector positioned relative to the x-ray source to detect x-rays transmitted by the x-ray source; and a computer programmed to; translate one of the x-ray source and the x-ray detector during a scan such that one of the x-ray source and the x-ray detector travels along a path with respect to an object to be imaged; acquire a tomosynthesis image dataset; and reconstruct one or more three-dimensional (3D) volumes from the acquired tomosynthesis image dataset, wherein the one or more 3D volumes correspond to one or more predetermined view directions, and wherein at least one of the one or more predetermined view directions is oriented outside of a central view direction. - View Dependent Claims (22, 23)
