Abstract

We demonstrate megahertz intravascular Doppler Optical Coherence Tomography (OCT). The OCT system relies on a 1.1 mm diameter motorized catheter and a 1.5 MHz Fourier Domain Mode Locked (FDML) laser. By resolving the phase shift between adjoint A-lines, the flow pattern image can be reconstructed. Imaging experiments were carried out in swine coronary artery in vitro at a speed of 600 frames/s. The MHz sweep rate not only allows us to investigate flow velocity of up to 37.5 cm/s without phase-unwrapping, but also enables dynamic flow imaging at high frame rate.
