Spectrum blood flow detection method of color spectrogram based on ultrasonic Doppler

Abstract

The spectrum blood flow detection method of the color spectrogram based on ultrasonic Doppler comprises the following steps: firstly, obtaining a Doppler blood flow spectrogram by adopting an ultrasonic Doppler imaging technology, and measuring a blood flow speed maximum value and a blood flow speed minimum value in the Doppler blood flow spectrogram; carrying out edge extraction on the ultrasonicspectrogram to obtain a region of interest; performing feature extraction on the region of interest to obtain edge features and region features corresponding to the region of interest; constructing aradial basis function neural network model by taking the edge features and the region features as input layer vectors, and analyzing the input layer vector features in a neural network to obtain output quantities related to the blood vessel features; correcting the blood vessel characteristic related output quantity according to the blood flow speed maximum value and the blood flow speed minimumvalue to obtain blood flow speed output; the blood vessel area can be accurately marked and distinguished, the blood flow speed is corrected, and auxiliary diagnosis of the exact illness state is facilitated.

Description

technical field [0001] The invention relates to the field of medical ultrasonic imaging detection, in particular to a spectral blood flow detection method based on an ultrasonic Doppler color spectrogram.
