Claim One:
1. A method, comprising: scanning a region of interest with an imaging system, during a contrast agent based perfusion scan, at a temporal sampling rate during contrast agent uptake in the region of interest, and generating time frame data indicative of the scanned region of interest with a reconstructor; determining a change in an amount of contrast agent in the region of interest from the time frame data with a contrast detector; generating a contrast signal indicating the change in the amount of contrast agent in the region of interest from the time frame data with the contrast detector; and scanning the region of interest with the imaging system at a lower temporal sampling rate, which is lower than the temporal sampling rate during the contrast agent uptake, in response to the generated contrast signal indicating the change in the amount of the contrast agent in the region of interest, wherein the lower temporal sampling rate varies during scanning the region of interest.
