Abstract

The invention relates to a method and a device for generating a compound ultrasonic blood flow image. The method includes: setting ultrasonic pulse emitting patterns according to a distance from an interested area to skin; when two or more emitting patterns are available, generating an ultrasonic image containing blood flow information for each emitting pattern; setting a weighting function for each ultrasonic image containing the blood flow information; using each weighting function to weight the corresponding ultrasonic image containing the corresponding blood flow information; superimposing the weighted ultrasonic images to generate the compound ultrasonic blood flow image.

Description

technical field [0001] The invention relates to the technical field of ultrasonic images, in particular to a method and device for generating composite ultrasonic blood flow images. Background technique [0002] Ultrasonic imaging is to radiate high-frequency ultrasonic pulse waves into the living body, and different waveforms are reflected from different interfaces in the living body to form an image, so as to determine whether there is a lesion in the living body. [0003] When imaging blood flow by means of ultrasound, a power Doppler imaging (PDI) method or a high-resolution power Doppler imaging (High Resolution PDI) method can generally be used. [0004] The power Doppler imaging method has a better penetration depth due to the use of long emission pulses in the time domain. When the distance from the blood vessel to the skin is long, the power Doppler imaging has a better effect, but its axial resolution not tall. High-resolution energy Doppler imaging uses short em...
