Claim 14:
15. A system, comprising:
an x-ray source that emits x-rays toward a subject to be imaged;
a detector that receives x-rays attenuated by the subject;
a data acquisition system (DAS) operably connected to the detector; and
a computer operably connected to the DAS and configured with instructions in non-transitory memory that when executed cause the computer to:
process projection data of a monitoring region of interest (ROI) of the subject from the DAS to measure a contrast signal of a contrast agent in the subject, the projection data acquired during a first contrast scan;
estimate a target acquisition timing for initiating a head and neck acquisition of a second contrast scan of the subject based on the contrast signal;
command injection of the contrast agent to the subject; and
initiate the head and neck acquisition at the target acquisition timing, wherein the head and neck acquisition is a first acquisition in time that is performed after the injection of the contrast agent is commanded.
