Abstract: A system(s), a computer-implemented method(s) and/or computer executable instructions encoded on a computer readable medium(s) obtains, for groups of a scan series for a subject, scout images for the subject that were acquired prior to planning the scan series and that include images of arms of the subject in different positions relative to the subject, designates, for each group of the groups, a scout image of the scout images with a position of the arms of the subject that corresponds to a position of the arms of the subject in the group as the reference image for X-ray source current modulation for the group, and utilizes the designated scout images for X-ray source current modulation for the series.

Abstract: A system(s), a computer-implemented method(s) and/or computer executable instructions encoded on a computer readable medium(s) receives a current position of arms of a subject for a group of a scan series, automatically identifies a scout image from a set of scout images with images of the subject with arms in different positions relative to the subject in which arms of the subject are at a position relative to the subject that corresponds to the current position of the arms of the subject, and utilizes the identified scout image for X-ray source current modulation for the group.
