Appl. No.:

14/868146

International Classification:

A61B 6/00
A61B 6/03

Abstract:

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.

Abstract:

Methods and systems are provided that obtain a scan prescription and receive physiologic feature or interest (FOI) measurements of an object of interest during a scan time. The methods and systems further compare at least one of the received physiologic FOI measurements with a predetermined threshold range, and determine a scan setting by evaluating an acquisition rule set based on the physiologic FOI measurement.
