Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method includes upon a first contrast injection, processing acquired projection data of a subject to measure a contrast signal of the first contrast injection, estimating a time when a venous return to baseline (VRTB) of the first contrast injection is to occur based on the contrast signal, and commanding initiation of a second contrast injection at the estimated time.

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 a monitoring area of a subject to measure a contrast signal of the contrast agent, estimating two or more target times of the contrast agent at the monitoring area of the subject based on the contrast signal, and carrying out a contrast scan that includes a two or more acquisitions each performed at a respective target time.

Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon a first injection of a contrast agent, processing acquired projection data of a monitoring area 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, generating a scan prescription for the contrast scan based on when each of the plurality of zones are estimated to occur, and upon a second injection of contrast agent, performing the contrast scan according to the scan prescription.

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.

Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon an injection of a contrast agent, performing a plurality of perfusion acquisitions of a first anatomical region of interest (ROI) of a subject with the imaging system, processing projection data of the first anatomical ROI obtained from the plurality of perfusion acquisitions to measure a contrast signal of the contrast agent, performing a plurality of angiography acquisitions, each angiography acquisition performed at a respective time determined based on the contrast signal, and performing one or more additional perfusion acquisitions between each angiography acquisition.

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.
