Embodiment 1

[0059] see figure 1, a bone fragment segmentation method of a three-dimensional image of the present embodiment, comprising:

[0060] S1. Acquire a three-dimensional image to be segmented.

[0061] It should be noted that the three-dimensional image to be segmented is a three-dimensional MRI (Magnetic Resonance Imaging, nuclear magnetic resonance imaging) image. MRI displays the internal information of the body in the form of images, and has the advantages of non-invasive, multi-modal, and accurate positioning.

[0062] S2. Using a segmentation model to identify the 3D image to be segmented to obtain a 3D bone fragment segmentation result.

[0063] Wherein, the segmentation model includes a feature extraction module, an intermediate module and a segmentation module.

[0064] Specifically, step S2 uses a segmentation model to identify the 3D image to be segmented to obtain a 3D bone fragment segmentation result including:

Abstract

The invention discloses a broken bone segmentation method and device for a three-dimensional image, computer equipment and a storage medium, and belongs to the field of intelligent medical treatment.According to the broken bone segmentation method for the three-dimensional image, the three-dimensional image serves as input, feature extraction is conducted on the three-dimensional image to be segmented through a feature extraction module in a segmentation model to obtain a basic feature map, and the correlation of tissues in the three-dimensional image is considered; the basic feature map is subjected to feature extraction through the middle module to obtain the segmentation map with the same size as the original to-be-segmented three-dimensional image, the segmentation map and the basic feature map are fused through the segmentation module, then the three-dimensional broken bone segmentation result is obtained, the segmentation time is saved, and the segmentation precision and efficiency are improved.

Description

technical field [0001] The invention relates to the field of intelligent medical treatment, in particular to a bone fragment segmentation method, device, computer equipment and storage medium of a three-dimensional image. Background technique [0002] Fractures are a common disease. More severe fractures often have broken bones. If broken bones are missed during surgery, serious consequences may result. The existing traditional segmentation method is mainly to understand the image through artificial subjective consciousness, so as to extract specific feature information, such as: gray level information, texture information and symmetry information, etc. to realize the segmentation of bone fragments. However, this segmentation method is only suitable for specific images. Good segmentation results, but there are problems that the segmentation results are too rough and the segmentation efficiency is low. With the emergence of artificial intelligence, especially deep learning, ...
