摘要

We describe power optical Doppler tomography (ODT) imaging in phase-resolved optical coherence tomography (OCT) capable of providing the precise location of blood flow in human skin. The power Doppler signal is the squared amplitude of the Doppler signal. By properly setting the intensity threshold and priority displaying Doppler power in phase-resolved OCT, we obtained a Doppler power tomography image of the blood flow in human skin. Power Doppler tomography uses only the amplitude information, so it is not susceptible to aliasing and Doppler flow angle and provides more accurate and smooth imaging of the location of the blood vessels in human skin than Doppler velocimetry. We also modified the phase-resolved algorithm we published before and used it to do Doppler tomography and M-mode Doppler imaging. The dynamic of blood flow in chick chorioallantoic membrane (CAM) was studied using M-mode Doppler imaging.
