Embodiment

[0022] The flow chart of the present invention is as figure 1 As shown, the high-fidelity three-dimensional model volume rendering method based on knee joint CT images of the present invention includes the following steps:

[0023] 1) Preprocessing the original knee joint CT image;

[0024] 2) The ray projection method is used to complete the three-dimensional visualization of the CT image of the knee joint.

[0025] The above-mentioned optimized preprocessing of the original knee joint CT image includes the following steps:

[0026] 11) Since it is unavoidable for patients to undergo CT scanning, there will inevitably be errors due to human operation and equipment, so it is necessary to perform Gaussian smoothing on the CT image to make it as real data as possible for the knee joint.

[0027] 12) Transform the format of CT data so that it can be processed by ray projection.

[0028] The above-mentioned ray projection method comprises the following steps:

[0029] 21...

Abstract

The invention discloses a method for drawing a high-fidelity model on the basis of CT (computed tomography) knee-joint images. The method includes the steps of (1) processing an original CT knee-joint image; and (2) completing three-dimensional visualization of the CT knee-joint image via a light ray projection method. The principle of the light ray projection method is utilized to reconstruct a three-dimensional model of the CT knee-joint image, the three-dimensional model is drawn according to the original CT knee-joint image, visualized effect of the CT knee-joint image is realized, study on medical images is facilitated, and a doctor is enabled to diagnose an illness state of a patient more accurately and faster. The method for drawing the high-fidelity model on the basis of the CT knee-joint images overcomes defects of other drawing methods, and can be used to visualize CT images and MRI (magnetic resonance imaging) images which are normally seen in the medical science. The method for drawing the high-fidelity model is practical and convenient, complies with expected requirements in result, can be used to draw three-dimensional models of medical organization (organs) quickly and accurately according to CT medical organization (organs) images, and meets different requirements of medical treatment and scientific research.

Description

technical field [0001] The invention is a high-fidelity model volume rendering method based on CT images of knee joints, in particular a method suitable for three-dimensional model volume rendering of human organs (tissues) based on CT images. The invention relates to an innovative technology of a high-fidelity model volume rendering method based on a CT image of a knee joint. Background technique [0002] With the continuous development of the social economy, especially the deepening of economic globalization and the emphasis on the knowledge economy, it has become a consensus to improve the level of patent development. Looking at home and abroad, the competition around patents is quite fierce, which is a significant symbol of the comprehensive strength and core competitiveness of a country or region. [0003] Medical image data visualization is an important means of auxiliary diagnosis and treatment in the clinic. In the medical field, a large number of CT images generate...
