Abstract

Accurate flow velocity estimation requires measurement of the Doppler angle, which is not available in general clinical applications. We introduce a simple method of estimating Doppler angle and average flow velocity by using conventional single-probing-beam optical Doppler tomography. Both Doppler angle and flow velocity are estimated by combining Doppler shift and Doppler bandwidth measurements. Using two sets of intralipid experiments corresponding to fixed Doppler angle and fixed flow speed, we demonstrate that the estimated values of the Doppler angle and flow velocity are in good agreement with true values. The principle is further validated by in vivo measurements.
