大多数医疗超声成像系统在3至10 MHz的频率范围内工作，可以分辨大约1 mm大小的物体。在20世纪80年代中期，新的换能器材料导致了第一个适用于高频（30-100 MHz）临床成像的换能器的开发。这些高频换能器可以提供具有微观分辨率的地下结构的图像。本文介绍了高频超声成像的基本原理，并讨论了这项新技术的六种应用：眼部成像、皮肤成像、基于导管的血管内成像、关节内成像、高频血流成像和小鼠胚胎发育的体内成像。这些例子说明了高频超声在医学和生物学中的一些潜在应用。
Most medical ultrasound imaging systems operate in the frequency range from 3 to 10 MHz and can resolve objects approximately 1 mm in size. In the mid 1980s, new transducer materials led to the development of the first transducers suitable for high-frequency (30-100 MHz) clinical imaging. These high-frequency transducers can provide images of subsurface structures with microscopic resolution. In this article, the authors introduce the basic principles of high-frequency ultrasound imaging and discuss six applications of this new technology: eye imaging, skin imaging, catheter-based intravascular imaging, intra-articular imaging, high-frequency flow imaging, and in-vivo imaging of mouse embryonic development. These examples illustrate a few of the potential applications of high-frequency ultrasound in medicine and biology.
