[Flash echo imaging].
Ultrasound transmission sometimes limits the lifetime of microbubble-based contrast agents. At this time, a very large echo signal (like a flash) is obtained for the initial transmission of the ultrasound after several seconds' suspension. Flash Echo Imaging (FEI) is a new technique which uses the signals of the bubble's collapse. This paper explains a principle of FEI and functions of the FEI's application for ultrasound diagnostic system. It is also shown that perfusion of the tissue can be visualized by using FEI methods.
