Title:
MULTI-FOCUS ULTRASONIC IMAGE STITCHING METHOD AND SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/119697
Kind Code:
A1
Abstract:
A multi-focus ultrasonic image stitching method. The stitching method comprises the following steps: S1, configuring n emission focuses (100) in an ultrasonic emission stage, wherein each emission focus (100) is correspondingly configured with different emission waveforms; S2, forming a corresponding feedback signal at each emission focus (100), and in a sound wave receiving stage, configuring demodulation signals with different frequencies to demodulate each feedback signal so as to obtain n focus images; S3, carrying out block matching on the n focus images, so that each focus image matches each corresponding emission focus (100) so as to obtain the n matching images; and S4, the matching image corresponding to each emission focus (100) comprising transition bands (200), and carrying out stitching processing on each transition band (200) to obtain a final multi-focus ultrasonic image. A multi-focus ultrasonic image is obtained by using the multi-focus ultrasonic image stitching method, the resolution of the image and the uniformity of the image are improved, and also the stitched transition bands of the multi-focus ultrasonic image are more uniform and real.
