X-RAY CONTROLLED CONTRACT AGENT INJECTION

摘要

An imaging system including a closed-loop controller (FC) for automatically adapting a power injector system (PJ).The power injector (PJ) injects contrast agent into an object (V) and the imager (100) acquires one or more images (AN, AN i ) of the object (V) with the contrast agent resident therein. The controller (FC) calculates a desired optimal injection rate from the images (AN, ANi). Controller (FC) then controls the injector(PJ) according to the calculated optimal injection rate.
