Abstract  

By transmitting coded ultrasound, coded excitation improves the signal-to-noise ratio, the frame rate and the penetration of the medical ultrasound imaging device. In order to provide guidelines to researchers in the field of medical ultrasound imaging, the newly advance of medical ultrasonic coded excitation was reviewed in this work. Introducing the basic principles of coded excitation and the characteristics of different types of code, gain in signal-to-noise ratio obtained by coded excitation, designing of types of code, tissue attenuation and nonlinear effect’s influence on pulsed compression were depicted. And the applications of coded excitation in B-mode ultrasound, elastography, high frequency ultrasound imaging, high frame rate imaging, synthetic aperture imaging, blood flow imaging and speckle reduction were reviewed regarding the properties of the coded excitation. Finally, advances of coded excitation was explored and prospected.
