title: [High-frequency ultrasound (HFUS) and its biomedical applications].
abstract: HFUS is ultrasound whose frequency is higher than 10MHz. HFUS imaging features very high resolution, which is up to 20 microm. HFUS is used to check the superficial organs such as eye ball and skin with extremely high resolution. When applied to small animals, HFUS is able to scan the body and the embryo in microscopic scale. The blood flow information in microcirculation can be detected if the high frequency Doppler technology is applied. Convenience, simplicity, real time and high resolution of HFUS have lead to a significant role in biomedical research and clinical applications.
