Abstract
Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon an injection of a contrast agent, processing acquired projection data of an anatomical region of interest (ROI) of a subject to measure a contrast signal of the contrast agent, determining when each of a plurality of zones of a contrast scan are estimated to occur based on the contrast signal, updating a scan prescription for the contrast scan based on when each of the plurality of zones of the scan protocol are estimated to occur, and performing the contrast scan according to the updated scan prescription.
