Abstract

The development of catheter-based ultrasound imaging began in the 1950s using large-diameter catheters and frequencies of between 1 and 10 MHz. In the 1970s, 360 degrees cross-sectional imaging of vessels was reported using multi-element or phase-array transducers. Since then, refinements in imaging frequency, catheter size, image quality, and computer-driven imaging platforms have transformed intravascular ultrasound (IVUS) from predominantly a research tool to an important clinical intervention.

摘要

基于导管的超声成像技术始于20世纪50年代，当时使用的是大口径导管，频率在1至10兆赫兹之间。20世纪70年代，有报道称使用多元或相控阵换能器实现了血管的360度横截面成像。从那时起，成像频率、导管尺寸、图像质量和计算机驱动成像平台的改进，已将血管内超声（IVUS）从主要作为一种研究工具转变为一项重要的临床干预手段。
