Summary:Embodiments of methods and/or apparatus for a radiographic imaging can include a plurality of x-ray sources disposed in a curve and a detector configured to revolve relative thereto. In one embodiment, a CBCT imaging method and/or apparatus can include performing a first scan at a first speed using stationary angularly distributed x-ray sources to acquire first CBCT projection data that impinge a detector of a first field of view (FOV), identifying an area of interest within the first FOV, and performing a second scan at a second speed using the x-ray sources acquire second CBCT projection data that impinge a portion of the detector of a second smaller FOV including the area of interest within the first FOV using second emissions by the x-ray sources, where the second speed is greater than the first speed.
