摘要:
Methods and systems are provided for adaptive scan control. In one embodiment, a method comprises: while performing a scan of a scan subject, processing acquired projection data to measure a contrast level responsive to the contrast level increasing above a first threshold, automatically switching the scan from a first scan protocol to a second scan protocol responsive to the contrast level decreasing below a second threshold, automatically switching the scan from the second scan protocol to the first scan protocol and responsive to the contrast level decreasing below a third threshold, automatically ending the scan. In this way, multiple scan protocols, such as angiography and perfusion scan protocols, can be interleaved within a single scan without the use of a separate timing bolus scan.
