| titleOfInvention | Optical coherence tomography angiography method, device, electronic equipment and storage medium |
| abstract | The present application relates to the field of optical coherence tomography, and in particular to an optical coherence tomography angiography method, device, electronic equipment and medium. The method includes: acquiring time-domain signals of the target area; Perform scale expansion to obtain N×k multi-scale signals; perform Fourier transform on each multi-scale signal and take logarithm to obtain axial frequency domain signals in logarithmic space; Segmentation of domain signals to obtain enhanced signals; divide N×k enhanced signals into k groups of single-scale signals based on k scales, and perform decorrelation calculation on each group of single-scale signals to obtain single-scale blood flow signals; based on k groups of single-scale signals The blood flow signal obtains a multi-scale blood flow signal. The present application improves the accuracy of OCTA image processing without reducing the axial resolution of blood flow. |
