超声成像是临床医学中经常使用的一种多用途的方式，很可能是因为它的低成本，对患者的低风险，以及实时提供图像的能力。通常在临床环境中使用的超声波频率在2到12兆赫之间。较低的频率产生更高的分辨率，但深度穿透有限；更高的频率产生更高的分辨率，但穿透深度有限。高频超声（HFUS）显示出检测皮肤某些变化的希望，这对早期检测与压疮形成和伤口愈合相关的变化具有重要意义。本文的目的是概述HFUS在皮肤中的应用，并就其在检测与压力相关的皮肤变化方面的应用进行一些讨论。
Ultrasound imaging is a versatile modality frequently used in clinical medicine, most likely due to its low cost, low risk to patients, and the ability to provide images in real time. Ultrasound used typically in clinical settings has frequencies between 2 and 12 MHz. Lower frequencies produce greater resolution but are limited in depth penetration; higher frequencies produce greater resolution, but depth of penetration is limited. High-frequency ultrasound (HFUS) shows promise for detection of certain changes in the skin and this has implications for early detection of changes associated with pressure ulcer formation and wound healing. The purpose of this article was to provide an overview of where HFUS has been used with the skin and provide some discussion on its utility with detecting skin changes related to pressure.
