Recent Advances in Intravascular OCT Technology

Abstract

Intravascular optical coherence tomography (OCT) is a catheter-based invasive imaging system. To determine whether coronary revascularization is appropriate and to perform stent evaluation in a catheterization laboratory, OCT examinations are carried out. In this talk, we present the on-going clinical studies to find benefits of OCT-guided stenting using a contour plot and briefly report computational OCT-derived fractional flow reserve in patients. Finally, we discuss the recent developments in a high speed, low noise optical rotary junction and an extended depth-of-focus optical probe.
