1. A method, comprising:
processing acquired projection data of a monitoring area of a subject to measure a contrast signal of a contrast agent delivered to the subject;
determining a hemodynamic marker of the subject based on the contrast signal;
generating a scan prescription for a multi-phase contrast scan based on the determined hemodynamic marker of the subject, including determining at least one of a number of acquisition phases to use for the multi-phase contrast scan and an acquisition timing parameter of the multi-phase contrast scan, based on the determined hemodynamic marker of the subject; and
performing the multi-phase contrast scan according to the scan prescription.
