Transvaginal four-dimensional hysterosaIpingo-contrast sonography (4D-HyCoSy) is a new kind of ultrasonic imaging technique, which can clearly and dynamic display the shape and patency of fallopian tube. It also has the advantages of no radiation and high accuracy. This article investigates the multiple teaching modes based on the dynamic ultrasound imaging characteristics, as well as focusing on the combination of theory and practice, aim at improving the teaching effectiveness and quality of the new technology.
