Embodiment Construction

[0034] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0035] At present, in the application of IVUS images, the actual ultrasound images generally have many problems such as speckle noise, low signal-to-noise ratio, and low contrast. It is difficult to make an accurate distinction between benign and benign tissue areas, but the speckle noise of ultrasound images also contains important information useful for diagnosis, especially its distribution status and shape features often contain important lesion information, and excessive The smooth filtering is at the expense of blurring ...

Abstract

The invention provides an ultrasonic image processing method and device and electronic equipment. The method comprises the steps of obtaining a to-be-processed intravascular ultrasonic image, taking the intravascular ultrasonic image as a current ultrasonic image, and executing the following image processing steps of decomposing the current ultrasonic image according to a preset transformation algorithm to obtain a plurality of component images, performing preset filtering processing on at least one bottom-layer component image except the highest-layer component image in the plurality of component images, taking the filtered bottom-layer component image as a current ultrasonic image, and continuing to execute the image processing step to reach a preset number of times, and according to an inverse sequence of the decomposition sequence, sequentially carrying out inverse operation of a preset transformation algorithm on the filtered component image corresponding to each decomposition until the intravascular ultrasonic image after speckle noise suppression is obtained. According to the method, image detail features can be reserved and enhanced while speckle noise is suppressed, and the method is of great significance to diagnosis of clinical pathology.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a processing method, device and electronic equipment for ultrasonic images. Background technique [0002] Intravascular ultrasound (IVUS) imaging is a new diagnostic method that has been clinically used in the diagnosis of vascular lesions in recent years. Pathological components, such as calcification, fibrous tissue, lipid core and plaque rupture, ex vivo, etc. Therefore, it is easier to detect early vascular lesions than coronary angiography, which can only provide long-axis images of arteries. At present, IVUS is being more and more widely used to evaluate the characteristics and degree of coronary atherosclerosis. It is considered as the "gold standard" for the diagnosis of coronary heart disease, and is used to guide the selection of interventional treatment methods and evaluate the effect of interventional treatment. [0003] In the application of IVUS...
