This disclosure relates to the field of Optical Coherence Tomography (OCT). This disclosure particularly relates to an OCT system with improved motion contrast. This disclosure particularly relates to motion contrast methods for such OCT systems. The OCT system of this disclosure may have a configuration that scans a physical object, which has a surface and a depth, with a beam of light that has a beam width and a direction acquires OCT signals from the scan forms at least one A-scan using the acquired OCT signals forms at least one B-scan cluster set using the acquired OCT signals that includes at least two B-scan clusters that each include at least two B-scans. The B-scans within each B-scan cluster set are parallel to one another and parallel to the direction of the beam of light. The OCT system may have a configuration that calculates OCT motion contrast using the at least one B-scan cluster set. This OCT system may form and display an image of the physical object.
