Embodiments comprise tomosynthesis systems and methods for creating a reconstructed image of an object from a plurality of two-dimensional x-ray projection images. These systems comprise: an x-ray detector; and an x-ray source capable of emitting x-rays directed at the x-ray detector; wherein the tomosynthesis system utilizes asymmetric image acquisition geometry, where θ1≠θ0, during image acquisition, wherein θ1 is a sweep angle on one side of a center line of the x-ray detector, and θ0 is a sweep angle on an opposite side of the center line of the x-ray detector, and wherein the total sweep angle, θasym, is θasym=θ1+θ0. Reconstruction algorithms may be utilized to produce reconstructed images of the object from the plurality of two-dimensional x-ray projection images.

摘要： A technique is provided for non-uniform weighting in back-projection calculations in tomosythesis. The non-uniform weighting may include weighting based on a count map of the number of times pixels of individual slices are traversed by radiation in different projections. Weighting may also include non-uniform functions for contributions of features at different slice level to the sensed X-ray attenuation system response inconsistencies are accounted for by further weighting based upon projection maps which may be created in separate system calibration or configuration routines.

摘要： The subject matter disclosed herein relates to X-ray imaging systems, and more specifically to digital X-ray imaging systems. In one embodiment, an imaging system includes an X-ray source configured to emit X-rays. The imaging system also includes an X-ray detector configured to detect the emitted X-rays and produce a corresponding electrical signal. The imaging system also includes a gantry configured to at least partially revolve the X-ray source and the X-ray detector about a primary rotational axis. The X-ray detector is coupled to the gantry so that a diagonal of the X-ray detector is oriented substantially perpendicular to the primary rotational axis.

摘要： A method and system for motion estimation and compensation are disclosed. Initially, a set of one or more initial images is reconstructed using acquired imaging data. Further, one or more regions of interest are identified in this set of reconstructed initial images. At least a set of filters is applied to the identified regions of interest to generate a sequence of filtered images. Particularly, each of the filtered images in the generated sequence of filtered images includes data acquired near a different reference point. Subsequently, a motion path corresponding to each region of interest is determined based on one or more correspondences in the sequence of filtered images.
