Abstract:

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 potentially applied in all kinds of catheters and is more economical and practical. Therefore, in future researches, innovation and design of catheter materials for catheter fabricating will play an important role in promoting the real-time ultrasonic localization of catheters.
