Problems solved by technology

However, although the current ultrasound-assisted teaching system can realize both pictures and texts and step-by-step teaching, it is only when the user selects a standard section that the system displays the standard image of the section and related graphic explanations. Need to hold the probe with one hand, it is inconvenient to select the required section
In addition, the existing ultrasonic teaching system has poor operation interaction, and the system cannot give feedback according to the real-time operation of the user. Therefore, the user cannot judge the correctness of his own operation well, nor can he obtain the knowledge based on his own situation in the actual operation link. effective guidance

Embodiment 1

[0039] Embodiment 1: Matching method based on image blocks (similarity calculation)

[0040] Such as figure 2 As shown, it discloses the ultrasound-assisted scanning method of the first embodiment of the present invention, and this embodiment realizes image matching based on the pattern matching method of image blocks. This embodiment can be divided into two stages: a pattern matching stage of determining matching points (step S12 ) and a searching stage of screening optimal matching library images (step S13 ). Among them, the matching points that match all the feature points one by one are determined on the real-time image through similarity calculation, and the library image with the highest similarity is screened out according to the matching degree of all feature points in each library image with the corresponding matching points. Here, the matching The degree especially refers to the similarity between the two.

[0041] Before determining the matching points, the metho...

Embodiment 2

[0063] Embodiment 2: Matching method based on image blocks (topological properties)

[0064] Such as image 3 As shown, it discloses the ultrasound-assisted scanning method of the second embodiment of the present invention. This embodiment also implements image matching based on the pattern matching method of image blocks, and is also divided into two stages: the pattern matching stage of determining the matching points ( Step S22) and the search phase of screening the best matching library images (step S23). The specific process of determining the matching point is the same as that in Embodiment 1, and will not be repeated here. In this embodiment, when screening the optimal matching library images, the topological properties of the feature points are used for screening instead of the similarity calculation results. For the feature points of each library image, its relative position relationship on the plane is fixed. If the current real-time image and the library image are...

[0070] Alternative Implementation: Matching Point Confirmation Process with Reduced Calculation

[0071] When determining the matching points in the above-mentioned embodiments 1 and 2, if the size of the template is large, a large amount of calculation will result. In another alternative embodiment, the present invention determines the matching points of the feature points of each library image based on the following steps, and the specific method described in any one of embodiments 1 and 2 can be used when screening the optimal matching library image. First, the search range corresponding to each feature point is still determined on the real-time image, and the specific process is the same as in the above two embodiments.

[0072] Then determine a template of a specific size centered on each feature point on the library image. After the template image A is taken out, A is an m*n matrix (m, n is the size of the template), and the template of A'A is calculated. Eigenvalue λ=[...

Abstract

The invention discloses an ultrasonic-assisted scanning method and system. On the basis of generating real-time ultrasonic images, the method performs a matching operation on the acquired real-time images and library images in the image library, thereby giving immediate feedback to the user on the correctness of the current scanning operation. The method can further output graphic and textual help information according to the matching result. If the current real-time image is a standard section image of a certain tissue or organ, the relevant graphic information of the standard section will be automatically called up to improve the convenience of operation. If the standard section image cannot be obtained, the user will be prompted how to adjust the position of the probe so as to obtain the desired image quickly and accurately. The method and system of the invention improve user interaction and user guidance, and can significantly improve the effect of auxiliary scanning.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic imaging, and relates to an ultrasonic-assisted scanning method and system. Background technique [0002] Ultrasound instruments are generally used by doctors to observe the internal tissue structure of the human body. The doctor places the operating probe on the skin surface corresponding to the part of the human body to obtain an ultrasonic image of the part. Due to its safety, convenience, non-destructive, and cheap features, ultrasound has become the main auxiliary means for doctors to diagnose. Due to the complexity of the operation of ultrasound equipment, it is necessary for the operating doctor to have a very clear understanding of the spatial structure of each organ and tissue of the human body in order to make a standard section of each organ and tissue. Newly hired ultrasound doctors, clinicians in emerging fields, and private clinics Many groups of people, such as doctors and some n...
