Abstract: 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.

Abstract: Methods and systems are provided for adaptive scan control. In one embodiment, a method for a computing device communicatively coupled to an imaging system includes, selecting a scan protocol, displaying an adaptive scan protocol graphical user interface (GUI) on a display device coupled to the computing device, adjusting one or more parameters of the scan protocol in response to user input to the adaptive scan protocol GUI, updating a visual representation of the scan protocol displayed via the adaptive scan protocol GUI in correspondence to the adjustment of the one or more parameters of the scan protocol, and storing the adjusted scan protocol in memory of the computing device.
