Claim Text:
1. A method of contrast-enhanced computed tomography (CT) imaging, comprising: (a) repeatedly scanning a target region at a frequency during a session of multiple complete scans, each scan in the session of multiple complete scans comprising emitting x-ray radiation toward the target region from a plurality of angular views, the frequency at which complete scans are performed in the session initially being a first rate; (b) monitoring, during the session of multiple complete scans, an indicator of attenuation of radiation by a contrast-enhanced first structure within the target region; (d) after detecting an increase of the attenuation, increasing the frequency at which complete scans are performed in the session to a second rate; and (e) after detecting a decrease in the attenuation after (d), decreasing the frequency at which complete scans are performed in the session to a third rate.
