摘要

We propose an algorithm to extract the angles of vessels for the correction of flow measurements in circumpapillary Doppler OCT scans. Firstly, we register a volume to two reference scans in order to determine the physiologically correct structure of the volume. Then, vessels are segmented in the volume and the angles are calculated and stored in a look-up table. After having registered the circular scan to the volume by using the projection along the z-axis, the angles can be extracted from the look-up table. Repeatability measurements of flow parameters on 5 vessels of a healthy subject are presented.
