Basics of adjustment of ultrasonic blood flow imaging

Abstract

Ultrasonic blood flow imaging such as color Doppler imaging or power Doppler imaging is a very useful function in diagnosis of abnormalities of vessels and organ function. Recently, advanced dynamic flow and superb microvascular imaging have made it possible to observe more fine and low-velocity blood flow in detail. In each of these modes, there are several switches for adjusting the conditions, but they are rarely used. In this paper, in order to make better adjustments and obtain correct information from the blood flow imaging mode, I will explain the meaning of those condition adjustments and the key points of the adjustment method. The names of modes and adjustment items refer to the ultrasound systems made by Canon Medical Systems Corporation.
