Basics of ultrasound flow imaging

Abstract

Ultrasound flow imagining is a technique used to display blood flow information as images. Nowadays, it is possible to obtain detailed information on the direction, velocity, and characteristics of blood flow by displaying the presence or absence of blood flow and its direction in color in real time. However, blood flow imaging is characterized by use of the Doppler effect in contrast to B-mode, which uses amplitude information. In addition, various ultrasound flow imaging technologies using the Doppler effect have now been developed, and it is important to understand the characteristics of these technologies and use them appropriately.
