Abstract

Traditional phase-resolve Doppler method demonstrates great success for in-vivo imaging of blood flow and blood vessel. However, the phase-resolved methods always require high phase stability of the system. During phase instable situations, the performance of the phase-resolved methods will be degraded. We propose a modified Doppler variance algorithm that is based on the intensity or amplitude value. Performances of the proposed algorithm are compared with traditional phase-resolved Doppler variance and color Doppler methods for two phase instability systems. The proposed algorithm demonstrates good performances without phase instability induced artifacts.
