声学脉冲反射法是一种相对较新的技术，可对人体气道进行无创测量。该技术包括将一个声学脉冲通过受试者的口腔导入气道。对产生的反射（“回声”）进行适当分析，就能够重建面积 - 距离函数。与已有的X射线头影测量法和CT扫描方法相比，该技术的无创特性具有显著优势，使其在耳鼻喉问题和睡眠呼吸暂停的研究以及患者的麻醉管理方面极具吸引力。本文介绍了声学反射法的原理和局限性，讨论了以往的研究工作，并提出了一些改进措施：该技术目前正在临床应用。
Acoustic pulse reflectometry is a relatively recent technique which allows the non-invasive measurement of human airways. The technique consists of guiding an acoustic impulse through the subject's mouth and into the airway. Suitable analysis of the resulting reflection (the 'echo') allows a reconstruction of the area-distance function. The non-invasive nature of the technique offers significant advantages over the established methods of x-ray cephalometry and CT scanning, and makes it very attractive for the investigation of ENT problems and sleep apnoea, and in the anaesthetic management of patients. This paper describes the theory and limitations of acoustic reflectometry, discusses previous work, and suggests some modifications: it is currently being implemented clinically.
