Intravascular ultrasound (IVUS) imaging evolved from early large catheters to advanced cross-sectional vessel imaging. Technological improvements have made IVUS a vital clinical tool, moving beyond its research origins.

Area of Science:

  • Medical Imaging
  • Cardiovascular Technology
  • Biomedical Engineering

Background:

  • Catheter-based ultrasound imaging originated in the 1950s with large catheters and low frequencies (1-10 MHz).
  • Early advancements in the 1970s introduced 360-degree cross-sectional vessel imaging using multi-element transducers.

Purpose of the Study:

  • To trace the historical development and technological evolution of intravascular ultrasound (IVUS).
  • To highlight the transition of IVUS from a research instrument to a critical clinical intervention.

Main Methods:

  • Review of historical advancements in catheter-based ultrasound technology.
  • Analysis of key innovations in transducer design, imaging frequency, and computer platforms.

Main Results:
