| titleOfInvention | Optical coherent blood flow radiography method and system based on multi-dimensional feature space |
| abstract | The invention discloses an optical coherent blood flow radiography method and system based on a multi-dimensional feature space. Collecting OCT scattering signals of scattering signal samples in three-dimensional space; constructing a three-dimensional characteristic space by combining morphological characteristics, the inverse signal-to-noise ratio of OCT scattering signals and decorrelation coefficients through a classifier, and realizing classification of dynamic blood flow signals and static tissue signals; the method comprises the following steps: processing the OCT scattering signal by adopting first-order and zero-order autocovariance to obtain the reciprocal of a signal-to-noise ratio and a decorrelation coefficient; constructing a signal-to-noise ratio reciprocal-decorrelation coefficient feature space; determining the upper bound of static signal distribution and the lower bound of dynamic signal distribution, and dividing the characteristic space of the reciprocal signal-to-noise ratio-decorrelation coefficient into three regions; extracting dynamic signals in the transition region by adopting a morphological mask; and obtaining a classification result by combining the signal of the dynamic region and the dynamic signal extracted from the transition region, and generating a blood flow radiography result. The invention can obviously inhibit the artifact problem caused by noise, improve the contrast ratio of blood flow and background and improve the continuity of blood vessels. |
