Abstract: Systems and methods for synthesizing a two-dimensional (2D) image of an organ of a patient by obtaining an pre-exposure x-ray image of the organ in order to ascertain parameters needed for acquisition of 2D (tomosynthesis) projection images of the organ, imaging the organ to obtain a plurality of 2D (tomosynthesis) projection images of the organ, and generating a synthetic 2D image of the organ from a combination of both the plurality of tomosynthesis projection images and the pre-exposure x-ray image.

Abstract: Methods and systems are provided for dynamic collimation adjustment during various x-ray imaging and image-guided procedures. In one example, collimation for an x-ray mammography system is adjusted based on a volume of interest, and further based on a workflow step of an imaging procedure. As an example, prior to a target selection, collimation may be adjusted to irradiate a larger volume of interest and x-ray system acquisition parameters, and hence, a greater area of a detector is irradiated; and after target coordinates are selected (e.g., for an interventional procedure), collimation may be adjusted to irradiate a reduced volume of interest based on the selected target and x-ray system acquisition parameters, and hence, a smaller area of detector is irradiated.
