title: Ultrasound and its various modes in use, part II: Real-time scanners.
abstract: Real-time scanners process information as they receive it, enabling structures to be viewed as they are scanned. This offers the advantage of faster scanning; however, image quality may not be as good as that of conventional scanners. Real-time scanners are used for a wide range of studies, but have not replaced B-mode and M-mode scanners to the extent envisioned by early developers.
