Intravascular Frequency-domain optical coherence tomography imaging system

We present a Frequency-domain optical coherence tomography (FD-OCT) system for intravascular imaging. The whole system consists of 4 parts: imaging catheter (IC), motion controller (MC), optical engine (OE) and data acquisition and processing module (DAPM). By using swept laser source with 50 KHz sweep speed and high speed optical rotary jiont, we can get 100 frames per second (fps) and scan 20 mm vessel per second.
