Methods and systems for an adaptive perfusion scan

Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon an injection of a contrast agent, initiating a contrast scan of a subject according to a fallback scan prescription, processing acquired projection data of an anatomical region of interest (ROI) of...

Zusammenfassung:	Methods and systems are provided for adaptive scan control. In one embodiment, a method includes, upon an injection of a contrast agent, initiating a contrast scan of a subject according to a fallback scan prescription, processing acquired projection data of an anatomical region of interest (ROI) of the subject to measure a contrast signal of the contrast agent, identifying a peak in the contrast signal within a predetermined time frame, if the peak in the contrast signal is not identified within the predetermined time frame, updating the fallback scan prescription to generate an adapted scan prescription for the contrast scan based on the contrast signal, and performing a remainder of the contrast scan according to the adapted scan prescription, and if the peak in the contrast signal is not identified within the predetermined time frame, continuing the remainder of the contrast scan according to the fallback scan prescription.
