Three-dimensional visualization method and device

Abstract

The invention relates to a computer image processing field and the embodiment of the invention discloses a three-dimensional visualization method and an apparatus. The method includes: the CT image is preprocessed to highlight the image of an interested area; according to an image feature of an interested tissue, the image of the interested area is segmented to get the image of the interested tissue in the area; the tissue image comprising other tissues to be segmented inside is processed mathematically and morphologically; according to the image of every tissue, a three-dimensional reconstruction is made to obtain a three-dimensional image. The application of the technical proposal of the embodiment of the invention is capable of making the image data of a human body of an individual visualized, and helpful to show relations of spatial positions of each tissue accurately.

Description

technology neighborhood The invention relates to the field of computer image processing, in particular to a three-dimensional visualization method and device. Background technique Medical image visualization is to display human body information obtained by digital imaging technologies such as computerized tomography (CT) and magnetic resonance imaging (MRI) in a three-dimensional effect on the computer, thereby providing Structural information not available by traditional means. Because it can provide doctors with realistic three-dimensional images, it is convenient for doctors to observe and analyze from multiple angles and levels based on the provided images. Therefore, medical image visualization plays an important role in auxiliary diagnosis and medical teaching. The image visualization processing in the prior art mainly includes the following steps: Carry out segmentation processing on human body image data to obtain image data of various tissues of interest. For ex...

Then, for the finally obtained segmented image, the small cavities may be the "imprint" of the small tissues (such as blood vessels) inside it, or it may be the "imprint" of noise, resulting in the three-dimensional analysis of each tissue after segmentation. After reconstruction, when it is necessary to transparently display the images of each layer, it is difficult to judge whether the cavity is real tissue or noise, which makes it difficult to judge the spatial position relationship between various tissues. When the noise is serious, it may even make the geometric model The interior of the car is disorganized, which makes medical diagnosis difficult
