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 contrast signal of a contrast agent delivered to the subject, determining a hemodynamic marker of the subject based on the contrast signal, generating a scan prescription based on the determined hemodynamic marker of the subject, and performing a multi-phase contrast scan according to the scan prescription.
Claims14
A method, comprising:
- processing acquired projection data of a monitoring area of a subject to measure a contrast signal of a contrast agent delivered to the subject;
- determining a hemodynamic marker of the subject based on the contrast signal;
- generating a scan prescription for a multi-phase contrast scan based on the determined hemodynamic marker of the subject, including determining at least one of a number of acquisition phases to use for the multi-phase contrast scan and an acquisition timing parameter of the multi-phase contrast scan, based on the determined hemodynamic marker of the subject;
- and
- performing the multi-phase contrast scan according to the scan prescription.

A method for an imaging system, comprising:
- processing acquired projection data of a monitoring area of a subject to measure a contrast signal of a contrast agent delivered to the subject via injection;
- generating a scan prescription for a contrast scan of the subject, including determining at least one of a number of acquisition phases to use for the contrast scan and an acquisition timing parameter of the contrast scan, based on the measured contrast signal;
- and
- performing the contrast scan with the imaging system according to the scan prescription.
