高频超声成像实现了生物组织在微观水平上的高分辨率活体成像。采用中心频率120 MHz的三维超声显微镜观察人体皮肤结构，特别是真皮深层的皮脂腺。通过现有的测试设备测量观察区域的粘弹性和表面皮脂水平。脸颊的皮脂腺密度和表面皮脂水平均高于前臂。前臂的粘度低于脸颊的粘度。这些结果表明，皮脂腺除了分泌皮脂和一些激素的经典作用之外，还可以充当皮肤的垫子。高频超声成像有助于评估人体皮肤老化。
High frequency ultrasound imaging has realized high resolution in vivo imaging of the biological tissues at a microscopic level. Human skin structure, especially sebaceous glands at the deep part of the dermis, was observed by three-dimensional ultrasound microscopy with the central frequency of 120 MHz. The visco-elasticity and surface sebum level of the observed region were measured by established testing devices. Both sebaceous glands density and surface sebum level were higher in cheek than those in forearm. The viscosity of forearm was lower than that of cheek. These results suggest that sebaceous glands may act as cushions of the skin besides their classical role of secreting sebum and some hormones. High frequency ultrasound imaging contributes to the evaluation of human skin aging.
