Abstract
Methods and systems are provided for adaptive scan control. In one embodiment, a method includes processing acquired projection data of a monitoring area of a subject to measure a first contrast signal of a contrast agent administered to the subject via a first injection, initializing a contrast scan of the subject according to a fallback scan prescription, determining when each of a plurality of zones of the contrast scan are estimated to occur based on the contrast signal, generating a personalized scan prescription for the contrast scan based on when each of the plurality of zones are estimated to occur, and performing the contrast scan according to the personalized scan prescription after a second injection of the contrast agent.
