摘要： A tomosynthesis system for forming a three dimensional image of an object is provided. The system includes an X-ray source adapted to irradiate the object with a beam of X-rays from a plurality of positions in a sector, an X-ray detector positioned relative to the X-ray source to detect X-rays transmitted through the object and a processor which is adapted to generate a three dimensional image of the object based on X-rays detected by the detector. The detector is adapted to move relative to the object and/or the X-ray source is adapted to irradiate the object with the beam of X-rays such that the beam of X-rays follows in a non arc shaped path and/or a center of the beam of X-rays impinges substantially on the same location on the detector from different X-ray source positions in the sector.

摘要： A technique is provided for concurrently viewing volumes that may be rendered using visualization techniques incorporating one or more functions, such as depth-dependent weighting functions. In one aspect, the viewing technique may provide for the concurrent viewing of volumes, such as overlapping volumes, from different viewpoints. In accordance with this aspect, the relative position of display may convey the relative viewpoints. In addition, the viewing technique may provide for concurrently displaying volume renderings of a volume in which the volume renderings are generated using different functions, such as weighting and/or transfer functions. In this manner, the effect of the functions on visual properties of structures within the volume may be observed.

摘要： A technique is provided for generating a three-dimensional image from fluoroscopic projection images. The technique allows for the acquisition of fluoroscopic images at different perspectives relative to a region of interest. One or more three-dimensional images may then be reconstructed from the fluoroscopic projection images. The three-dimensional images may then be displayed to provide anatomic context for the fluoroscopic application. A fluoroscopic projection image, such as the most current fluoroscopic image, may be superimposed on the three-dimensional image if desired.

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, φasym, is φasym=θ1+θ0. Reconstruction algorithms may be utilized to produce reconstructed images of the object from the plurality of two-dimensional x-ray projection images.
