Problems solved by technology

[0003] Aiming at the shortcomings of the existing three-dimensional model reconstruction methods of blood vessels that require professionals to perform a large number of manual screening operations during the reconstruction process, the present invention considers designing an automatic screening rule for regions of interest in blood vessels, using a sliding window in each magnetic resonance image Carry out clipping, and obtain the contour lines of all tissues from the sliding window, identify and obtain the vessel contours from all contour lines, build a contour data set about the region of interest in the blood vessels, and finally perform a 3D model on the filtered blood vessel contours of interest Reconstruction, providing a "one-click" automatic reconstruction method of vascular 3D model with CT image data as input and vascular 3D model as output

[0065] Example: "One-click" automatic reconstruction of the 3D model of neck vessels

[0066] The present invention comprises the following steps, as figure 1 Shown:

[0067] According to the manually selected image, input A(x 1 ,y 1 )and Conduct a human-computer interaction.

[0068] The input A(x 1 ,y 1 )and Specifically: A(x 1 ,y 1 )and It is obtained by manual reading in the figure, and is used as human-computer interaction input information.

[0069] Initialize the sliding window and crop the first picture, such as figure 2 shown.

[0070] Specifically, the initialization of the sliding window is as follows: the space size of the sliding window in this example is initially set to [50,50].

[0071] The clipping of a picture is specifically: the manually selected image is used as the first image clipped by the sliding window, according to the manual input A(x 1 ,y 1 ), in this picture with A(x 1 ,y 1 ) and B(x 1 +50,y 1 +50) Draw X-O-Y and X'-O'-Y' co...

Abstract

The invention relates to a three-dimensional reconstruction technology, in particular to an automatic reconstruction method for a blood vessel three-dimensional model, and aims to reduce a large amount of manual operation in a medical three-dimensional reconstruction process and guide a sliding window to automatically cut a medical image blood vessel region of interest by utilizing a movement rule, Identify the blood vessel contour of the sliding window according to an identification rule, obtain independent blood vessel contours, form an ordered target blood vessel contour set, judge whether the sliding window continues to cut the next adjacent medical image or not by adopting an ending rule, and finally perform three-dimensional model reconstruction and output on the ordered target blood vessel contour set. In a three-dimensional model reconstruction process, one-time human interaction is needed so as to realize reconstruction and output from medical image input to a target blood vessel three-dimensional model.

Description

technical field [0001] The invention relates to a three-dimensional reconstruction technology, in particular to a method for automatic reconstruction of a blood vessel three-dimensional model. Background technique [0002] For 3D model reconstruction of blood vessels, the process adopted by the existing methods basically includes medical image data enhancement processing, manual screening of vascular regions of interest by professionals, and 3D model reconstruction. To perform screening and continuously adjust the parameters of the screening method to improve the screening effect, this process requires a lot of manual operations and consumes a long time of human labor, resulting in heavy work and a long period of reconstruction of the three-dimensional model of the blood vessel. Contents of the invention [0003] Aiming at the shortcomings of the existing three-dimensional model reconstruction methods of blood vessels that require professionals to perform a large number of...
