Abstract
Official abstract text for this publication.
A method includes scanning a region of interest, during a contrast agent based perfusion scan, at a predetermined temporal sampling rate during contrast agent uptake in the region of interest, and generating time frame data indicative of the scanned region of interest. The method further includes identifying a predetermined change in an amount of the contrast agent in the region of interest from the time frame data. The method further includes scanning the region of interest at a lower temporal sampling rate, which is lower than the temporal sampling rate during the contrast agent uptake, in response to identifying the predetermined change in the amount of the contrast agent in the region of interest.
First claim
Opening claim text (preview).
What is claimed is: 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 sig…
