Embodiment 1

[0038] Figure 1A It is a flowchart of a blood vessel image processing method in Embodiment 1 of the present invention. The embodiment of the present invention is applicable to the situation of removing jitter noise caused by respiration and heartbeat in the collected ultrasound images of blood vessels. The method is performed by a blood vessel image processing device, which is implemented by software and / or hardware, and is specifically configured in an electronic device capable of image processing, and the electronic device may be an independent computing device, such as a personal computer or a PC, etc. , may also be a data processing device contained in a medical imaging system, where the medical imaging device may be an ultrasonic diagnostic device.

[0039] Such as Figure 1A A blood vessel image processing method shown includes:

[0040] S110. Acquire a longitudinal sectional image of a blood vessel, where the longitudinal sectional image of a blood vessel includes a f...

Embodiment 2

[0056] Figure 2A It is a flowchart of a blood vessel image processing method in Embodiment 2 of the present invention. The embodiments of the present invention are optimized and improved on the basis of the technical solutions of the foregoing embodiments.

[0057] Further, the operation "smoothing the edge curve according to the positional relationship between the at least two turning points" is refined as "dividing the edge curve into at least three The initial curve segmentation segment; according to the overall direction of the blood vessel, at least two target curve segmentation segments are selected from each of the initial curve segmentation segments; two adjacent endpoints of the two adjacent target curve segmentation segments are grouped Turning point pairs, according to each group of turning point pairs, the target curve segment is translated, so that the at least two target curve segment segments are "collinear", so as to improve the processing method of smoothing...

Embodiment 3

[0078] image 3 It is a flowchart of a blood vessel image processing method in Embodiment 3 of the present invention. The embodiments of the present invention are optimized and improved on the basis of the technical solutions of the foregoing embodiments.

[0079] Further, the operation "rotate the first reference image, so that the target starting point of the edge curve in the first reference image coincides with the initial starting point of the edge curve in the first initial image, and make the The target end point of the edge curve of the first reference image coincides with the initial end point of the edge curve in the first initial image correspondingly "refinement" to "surround the first reference image around the target start point or the The target end point is rotated so that the target start point coincides with the initial start point, and the target end point coincides with the initial end point", so as to improve the rotation of the first reference image. ro...

Abstract

The embodiment of the invention discloses a blood vessel image processing method and device, an apparatus and a storage medium, and the method comprises the steps: obtaining a blood vessel longitudinal cutting image which comprises a first initial image comprising the upper wall of a blood vessel and a second initial image comprising the lower wall of the blood vessel; determining each turning point in the edge curve of the upper wall of the blood vessel in the first initial image, and smoothing the edge curve according to the position relation between the turning points to obtain a first reference image; rotating the first reference image to enable the target starting point and the target ending point of the edge curve of the first reference image to be correspondingly overlapped with theinitial starting point and the initial ending point of the edge curve in the first initial image respectively; and obtaining a target image according to the rotated first reference image and the second initial image. According to the technical scheme provided by the embodiment of the invention, under the condition that the overall posture of the original blood vessel is kept, jitter noise causedby respiratory heartbeat is removed, and the credibility of the diagnosis result obtained based on the blood vessel image is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a blood vessel image processing method, device, equipment, and storage medium. Background technique [0002] Carotid artery ultrasonography is an auxiliary examination for detecting abnormalities in arterial vessels, and is one of the effective means for diagnosing and evaluating carotid artery wall lesions. However, when scanning the carotid artery of the subject to be detected, since the blood flow will change with the change of the heartbeat frequency, the detected blood vessel image will be correspondingly thickened or thinned, which will lead to the longitudinal section of the carotid artery. Vibration occurs on the upper wall of the blood vessel, which is not conducive to the observation and effective diagnosis of the disease by medical staff. [0003] In the prior art, a decorrelation algorithm or a convolutional neural network is usual...
