    摘要: An imaging system comprises a digital radiation detector and radiation source. A detector transport moves the detector along at least a portion of a first curved path and a radiation moves the source along at least a portion of a second curved source path. The detector is configured to travel at least a portion of the first curved path, and the source is configured to travel at least a portion of the second curved path. The detector is configured to obtain a plurality of 2D projection images over a range of scan angles for reconstructing a 3D volume image using the plurality 2D projection images.

    摘要: A mobile radiography apparatus has a moveable (e.g., wheeled) transport frame and an adjustable column mounted at the frame. A boom apparatus supported by the adjustable column can support an x-ray source assembly. Certain exemplary methods and/or apparatus embodiments can provide mobile radiography carts a capability to direct x-ray radiation towards a subject from one or a plurality of different source positions, and reconstruct two-dimensional or three-dimensional tomosynthesis images where an imaging geometry of x-ray source positions to a radiographic detection array is not known for a plurality of x-ray tomosynthesis projection images. In one embodiment, an imaging geometry and tomosynthesis reconstruction(s) can be simultaneously determined by iteratively determining a current imaging geometry while iteratively monitoring a metric (e.g., stopping criterion) that approaches a prescribed or desired value associated with the tomosynthesis reconstruction.
