Embodiment

[0045] Such as figure 1 As shown, a multi-organ 3D reconstruction control method based on the urinary system can reflect the real structure of the organ, and the reconstructed 3D surface is smoother, including 4 stages of data preprocessing, surface rendering, mesh smoothing, and Unity3D model rendering. Specifically include the following steps:

[0046] S1. Acquire medical images of the urinary system, and obtain labeled data files after segmentation processing;

[0047] S2. According to the labeled data file, a triangular patch mesh model of the medical image of the urinary system is generated through a surface rendering algorithm based on depth-first traversal and contour line interpolation;

[0048] S3. Through the Laplacian grid smoothing algorithm based on distance weighting and linear interpolation, multiple iterative optimizations are performed on the triangular patch grid model;

[0049] S4. According to the optimized triangular mesh model, a three-dimensional recon...

Abstract

The invention relates to a multi-organ three-dimensional reconstruction control method based on a urinary system, and the method specifically comprises the following steps: S1, obtaining a medical image of the urinary system, and segmenting the medical image to obtain an annotation data file; S2, generating a triangular patch mesh model of the medical image of the urinary system through a surface drawing algorithm based on depth-first traversal and contour line interpolation according to the labeled data file; S3, through a Laplacian grid smoothing algorithm based on distance weighting and linear interpolation, carrying out multiple times of iterative optimization on the triangular patch grid model; and S4, according to the optimized triangular patch mesh model, rendering a three-dimensional reconstruction model of the medical image of the urinary system through a texture mapping algorithm. Compared with the prior art, the invention has the advantages that the problem that interpolation cannot be carried out due to irregular shapes and multiple areas of seminal vesicles and tumor organs in the urinary system is effectively solved, and the squamous effect on the surface of the three-dimensional reconstruction model is better eliminated.

Description

technical field [0001] The invention relates to the technical field of three-dimensional organ reconstruction, in particular to a control method for three-dimensional reconstruction of multiple organs based on the urinary system. Background technique [0002] At present, in order to realize the visualization of three-dimensional organs, researchers have developed many medical image processing toolkits, among which VTK+ITK and MITK are the most common. They can render CT and MRI images of the cerebral cortex, ankles, lung parenchyma, blood vessels, heart, etc. into three-dimensional organ models through surface rendering or volume rendering, and the reconstruction effect is good, but there is little work on multi-organ reconstruction with complex and irregular shapes. involve. Some organs in the human body, such as the urinary system, have irregular and complex shapes, and the organs reconstructed by the existing VTK visualization technology have a squamous effect, which bri...
