1. A computed tomography imaging system, comprising:
a rotating frame configured to rotate about a rotational axis;
an X-ray source disposed on the rotating frame and configured to emit X-ray radiation that traverses an examination region;
an X-ray controller configured to control the X-ray source;
a subject/object support configured to support a subject or object in the examination region;
a console, including:
a computer readable medium configured to store instructions; and
a processor configured to execute the instructions, wherein the instructions cause the processor to:
obtain a first scout image with arms of a subject up above shoulders of the subject;
obtain a second scout image with arms of the subject down by sides of the subject,
designate the first scout image as a reference image for X-ray source current modulation for a first group of a scan series where the arms of the subject are up above the shoulders of the subject;
designate the second scout image as a reference image for X-ray source current modulation for a second group of the scan series where the arms of the subject are down by the sides of the subject; and
command the X-ray controller to utilize the first scout image as the reference image for X-ray source current modulation for the first group of the scan series and the second scout image as the reference image for X-ray source current modulation for the second group of the scan series.
