We demonstrate a synthetic subaperture-based angle-independent Doppler flow calculation, using a line field spectral domain optical coherence tomography system. The high speed of the system features a high phase stability over the volume, which is necessary to apply synthetic subapertures in the aperture plane. Thus, the flow component for each subaperture can be reconstructed in postprocessing. Capillary phantom and in vivo retinal imaging experiments were performed to validate and demonstrate angle-independent Doppler flow calculation.
我们展示了一种基于合成子孔径的角度无关多普勒流速计算方法，该方法使用线场谱域光学相干断层扫描系统。系统的高速特点是体积内具有高相位稳定性，这是在孔径平面上应用合成子孔径的必要条件。因此，可以在后期处理中重建每个子孔径的流速分量。我们进行了毛细血管仿体和活体视网膜成像实验，以验证和演示角度无关的多普勒流速计算。
