摘　　要：背景:介入置管过程中,确认导管的位置至关重要。在急诊治疗中往往要求做到快速、准确地置管。超声能够提供实时图像并且对人体无害,因而在引导导管置入方面有很好的应用前景。目的:对比目前已发表的几类提高超声定位准确性的方法,同时展望体内导管超声实时精确定位技术未来的发展趋势和改进方向。方法:用计算机检索1990年1月至2015年4月Pub Med数据库以及Espacenet数据库相关文献或专利,以"catheter,ultrasonic guidance,ultrasound localization,enhanced localization"为检索词。结果与结论:增强导管超声定位准确性的方法可以归纳为2类,即通过改进超声仪器或超声定位系统来增强超声定位的准确性和通过改进导管本身来达到提高导管超声可视性的目的。相较之下,通过改进导管本身材质来提高其超声可视性的方法更加简单、操作简便、成本较低且适用性较广。因而在未来的研究中,导管材料的设计和创新对于体内导管超声实时精确定位技术的发展有重要的促进作用。BACKGROUND：To ensure the catheter position is very important for interventional catheters. In emergency, rapid and accurate catheter insertion is required. Ultrasound can real-time track the movement of catheters in vivo. It is safe to patient, which has exhibited a bright future in catheter placement. OBJECTIVE： To compare the current methods for improving ultrasonic localization methods and to prospect the future development and improvement of real-time ultrasonic localization of catheters in vivo. METHODS： Literature search was carried out based on PubMed （1990-01/2015-04） and Espacenet with the key words of ＂catheter, ultrasonic guidance, ultrasound localization, enhanced localization＂ for the initial retrieval of relevant articles. RESULTS AND CONCLUSION：To improve the image quality and increase the accuracy of catheter placement by ultrasound, recent efforts have been focused on two paths. One is to improve the resolution of ultrasonic images by enhancing ultrasound equipment or ultrasonic guidance system. The other is to modify catheter itself to obtain high acoustic impedance differential and improve its echogenicity. The latter approach can be potentialy applied in al kinds of catheters and is more economical and practical. Therefore, in future researches, innovation and design of catheter materials for catheter fabricating wil play an important role in promoting the real-time ultrasonic localization of catheters.
