[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...
