Carotid artery ultrasonic scanning three-dimensional reconstruction method and system

Abstract

The invention provides a carotid artery ultrasonic scanning three-dimensional reconstruction method and system. The carotid artery ultrasonic scanning three-dimensional reconstruction method comprisesthe steps of S1, obtaining model data; S2, resampling the model data to obtain a carotid artery model data source; S3, according to the carotid artery model data source, obtaining surface image images corresponding to the six surfaces forming a model of the carotid artery model data source; S4, splicing the six surface image images to form a carotid artery 3D model framework for display and output; S5, on the basis of the 3D model frame, according to a carotid artery model data source, obtaining a section image of a section, passing through two pixel points x1 and x2 on any surface, on the 3Dmodel frame; and S6, splicing the obtained section image and each surface image in the original carotid artery 3D model framework into a new 3D model. Compared with the traditional carotid artery two-dimensional longitudinal section diagram observation, the carotid artery two-dimensional longitudinal section diagram observation method has the advantage that the diagnosis accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasound, and mainly relates to a three-dimensional reconstruction method and system for carotid artery ultrasound scanning. Background technique [0002] Ultrasound imaging has become one of the most widely used clinical diagnostic tools because of its non-invasive, real-time, convenient operation, and low price. [0003] Carotid artery ultrasonic scanning technology is one of the ultrasonic imaging technologies. In the prior art, doctors usually hold the probe to scan the carotid artery. The direction of the probe is parallel to the direction of the carotid artery. After this operation, the carotid artery imaging image is obtained. For your doctor's reference. The above-mentioned prior art is mainly realized by manual assistance, so the scanning efficiency is low, and it is impossible to check the image in all directions. [0004] In order to solve the above problems, an automatic scanning d...

Problems solved by technology

The above existing technologies are mainly realized by manual assistance, so the scanning efficiency is low, and it is impossible to view the image in all directions

[0004] In order to solve the above problems, an automatic scanning device was invented. The image obtained by this device is different from the above-mentioned longitudinal scanning image parallel to the direction of the carotid artery, but a transverse scanning ultrasonic image perpendicular to the direction of the carotid artery. , the scanning image obtained by the automatic scanning device can only view each image in real time, so it is difficult to restore the aorta and bifurcation position of the carotid artery, so it is difficult to fully present the disease state of the carotid artery
