Title:
ULTRASONIC IMAGE PROCESSING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005069
Kind Code:
A1
Abstract:
An ultrasonic image processing method and apparatus, and an electronic device. The method comprises: obtaining an intravascular ultrasonic image to be processed (S102); using the intravascular ultrasonic image as a current ultrasonic image, and executing the following image processing steps: decomposing the current ultrasonic image according to a preset transformation algorithm to obtain multiple component images, performing preset filtering processing on at least one bottom-layer component image other than the highest-layer component image in the multiple component images, using the filtered bottom-layer component image as the current ultrasonic image, and continuing to execute the image processing steps for a preset number of times (S104); and according to an inverse sequence of the decomposition sequence, sequentially performing inverse operation of the preset transformation algorithm on the filtered component image corresponding to each decomposition until an intravascular ultrasonic image subjected to speckle noise suppression is obtained (S106). According to the method, detail features of an image can be reserved and enhanced while speckle noise is suppressed. The method is of great significance to clinical pathology diagnosis.
