Problems solved by technology

This method can mark the rib centerline, but it cannot solve the rib marking problem
At the same time, this method takes a long time to search for a large area, and cannot be applied to rib fractures (such as dislocated rib fractures or deformed ribs due to lesions), nor can it adapt to the situation where the rib area is incomplete.

Embodiment

[0048] figure 1It is a flow chart of the rib marking method provided by the embodiment of the present invention, please refer to figure 1 , the rib marking method provided in this embodiment includes the following steps:

[0049] S110: Acquire an image to be identified; the image to be identified includes a CT image;

[0050] S120: Input the image to be recognized into the image segmentation model to obtain the segmentation result; the image segmentation model is obtained by deep learning training based on the sample image and the corresponding rib label and rib centerline label, and can simultaneously segment ribs and rib centerlines, and the segmentation results include ribs Segmentation results and rib centerline segmentation results.

[0051] Figure 2-Figure 4 It shows the segmentation results obtained by segmenting CT images of patients with dislocation fractures, please refer to Figure 2-Figure 4 , the gray and white thin solid lines shown in the figure all indicat...

Abstract

The invention discloses a rib marking method, device and equipment and a training method of an image segmentation model, and the method comprises the steps: obtaining a to-be-identified image; Whereinthe image to be identified comprises a CT image; Inputting the to-be-identified image into an image segmentation model to obtain a segmentation result; Wherein the segmentation result comprises a ribsegmentation result and a rib center line segmentation result; And performing rib sorting and marking based on the segmentation result. According to the invention, rib adhesion and fracture conditions can be well handled, and each rib can be quickly sorted and marked.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a rib marking method, device, equipment and a training method for an image segmentation model. Background technique [0002] In the application of bone analysis, most of the data to be analyzed are serious. The gap between ribs is inherently short, usually due to the short distance between ribs, adhesions appear on the rib segmentation results. At the same time, when the scanning resolution is very low, the ribs segmented by the existing algorithm appear to be cohesive, and the corresponding rib labels cannot be automatically identified. Or the segmentation result of the same rib is discontinuous due to lesions such as rib fracture or bone cancer cell erosion. Therefore, there are certain difficulties in the rib centerline extraction and rib marking algorithm. [0003] In a method provided by the prior art, the connected domain is extracted from the result of rib segm...
