使用超声扫描仪（20 MHz A）描述正常人指甲盖的结构。尸检研究，包括检查干燥前后的甲板活检标本，并与体内结构进行比较。甲内可识别出两个隔室，即干燥和浅表隔室，超声速度为3103 m/s，潮湿和较深的隔室，超声速度为2125 m/s。整个指甲的超声波速度为2459 m/s，并且水含量为35%wt/wt。在指甲下方，可以看到来自甲床的回声。结论：超音波可用于无创性测量指甲厚度及检查指甲内部结构。
The structure of the normal human nail plate is described using an ultrasound scanner (20 MHz A). Postmortem studies, including examination of nail plate biopsy specimens before and after desiccation, were performed and compared with in vivo structures. Two compartments could be identified in the nail, ie, a dry and superficial compartment with the ultrasound velocity of 3103 m/s and a humid and deeper compartment with an ultrasound velocity of 2125 m/s. The ultrasound velocity of the entire nail was 2459 m/s, and the water content was 35% wt/wt. Underneath the nail, echoes from the nail bed were seen. Ultrasound was concluded useful for noninvasive measurement of nail thickness and examination of internal nail structure.
