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.

Various methods and systems are provided for mammogram imaging. In one example, a method for an x-ray mammography system includes determining, based on a pre-exposure image of a subject acquired with the x-ray mammography system before acquisition of one or more main images, that the subject has an implant; automatically adjusting one or more imaging parameters in response to determining that the subject has the implant; and acquiring the one or more main images with the adjusted one or more imaging parameters.
