Embodiment Construction

[0066] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0067] see Figure 1 to Figure 21 , the present invention provides a method for automatically generating left and right lung three-dimensional models based on CT images, comprising the following steps:

[0068] Step S1, data input, obtain the original image CT1, and reorganize it into three-dimensional stereo data according to the TAG array of the DICOM medical image, such as: Figure 1 to Figure 3 The images of the transverse, coronal, and sagittal planes are reconstructed in the form of MPR, and the images can be displayed and processed from different directions.

[0069] Step S2, data...

Abstract

The invention relates to the technical field of medical image processing, and discloses a method and system for automatically generating a left and right lung three-dimensional model based on a CT image in order to solve the technical problem that existing equipment is low in automation degree, and the method comprises the steps that S1, an original image is acquired and recombined into three-dimensional data; s2, the three-dimensional data are automatically selected for preprocessing, and a secondary image is obtained; s3, segmenting and marking the secondary image to generate a binary image; step S4, generating a Label mark graph of the same peripheral contour ROI, and clearing all pixel values; pixel points are screened, and Label image feature analysis is carried out; s5, extracting a third image from the second image, establishing a corresponding relation, automatically realizing separation of the left lung, the right lung and the bronchial tube, and marking the left lung and the right lung; s6, extracting left and right lung segmentation data; and S7, reconstructing a left and right lung 3D model. The process does not need human interaction intervention, the automation level is improved, and the problem of low automation degree is solved.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method and a system for automatically generating left and right lung three-dimensional models based on CT images. Background technique [0002] Under the premise that 3D visualization of medical CT images is more and more widely used, the efficiency of CT image processing and 3D reconstruction has become the focus of attention. How to quickly, accurately and automatically realize the 3D models of different tissues or organs in CT images. As the basis of individualized, precise and 3D visualization diagnosis and treatment research, it has increasingly become an urgent problem to be solved in scientific research and practical application. [0003] For the analysis and application of chest CT images, it often starts from the segmentation and 3D reconstruction of the left and right lung parenchyma. The automatic, efficient and accurate generation of 3D models of th...
