Cube data correlation-based imaging of small blood vessels

Abstract

We present a cube data correlation-based correlation mapping optical coherence tomography (cube-cmOCT) method to reconstruct small blood vessel maps. In the cube-cmOCT method, the two adjacent cube data are correlated to extract blood flow information. Both phantom experiments and in vivo experiments were performed to demonstrate the advantage of the proposed method in improving the SNR of blood vessel maps without increasing the window size in the xz plane and offering a clear image of the small blood vessels almost missed by the conventional cmOCT method.
