Which statement is true regarding cine and angio systems?

Cine and angio systems are specialized imaging techniques used primarily to visualize dynamic processes in the body, particularly in vascular studies. These systems differ from Automatic Exposure Control (AEC) systems in that they don't automatically adjust exposure based on the amount of radiation reaching the detector.

Cine systems capture a series of images to create a motion picture-like display of physiological processes, while angio systems focus on imaging blood vessels using contrast agents. Neither operates under the principles of AEC, which is designed to optimize exposure based on real-time imaging conditions.

In this context, recognizing that both cine and angio systems are not reliant on AEC technology reinforces the understanding of their function and operational design within the realm of medical imaging. Thus, the statement that cine and angio are not AEC systems reflects a correct understanding of their characteristics and operational frameworks.
