One Specific Velocity Mapping in Optical Coherence Tomography

摘要

The method of sign-sensitive mapping of one specific velocity (OSV) in a flow with complex geometry based on the principles of optical coherence tomography (OCT) is described. The mapping is controlled using two parameters, the value of velocity, V, and the accuracy of its determination, AV. Structural image and two OSV images (for positive and negative direction of motion) are obtained as a result of selecting and processing the relevant parts of the signal spectrum. The final image is a result of complexing these three and can be used as a Doppler equivelocity color map.
