Embodiment 1
[0042] figure 1 The flow diagram of the three-dimensional visualization method provided in this embodiment, as shown in the figure, the method includes:
[0043] Step 101: Obtain a CT image.
[0044] At present, medical CT data is acquired through CT. CT images are expressed in different gray levels, reflecting the degree of tissue absorption of X-rays. Therefore, like the black-and-white images shown in X-ray images, black shadows indicate low-absorption areas, that is, low-density areas, such as lungs with a lot of gas; white shadows indicate high-absorption areas, that is, high-density areas, such as bones. However, compared with X-ray images, CT has a higher density resolution, that is, a higher density resolution (density resolutiln). Therefore, although the density difference of human soft tissue is small, although the absorption coefficient is much close to that of water, it can also be imaged by contrast. Therefore, CT scan can better display the organs composed of...
Embodiment 2
[0126] Figure 12 A schematic structural diagram of a three-dimensional visualization device provided for this embodiment, as shown in the figure, the device includes:
[0127] The input unit 121 is used for inputting CT images.
[0128] For its principle, refer to the description of step 101 in Embodiment 1.
[0129] The preprocessing unit 122 is configured to preprocess the CT image input by the input unit 121 to highlight the image of the region of interest. Various existing preprocessing methods can be selected to preprocess the image to highlight the image of the region of interest.
[0130] For its principle, refer to the description of step 102 in Embodiment 1.
[0131] The segmentation unit 123 is configured to perform image segmentation on the image of the region of interest processed by the preprocessing unit 122, and acquire images of tissues of interest to the user in the region. Various segmentation methods in the prior art may be adopted as the segmentation m...
Embodiment 3
[0141] Figure 13 A schematic structural diagram of a three-dimensional visualization device provided for this embodiment, as shown in the figure, the device and Figure 12 The difference of the shown device is that the device of this embodiment may also include:
[0142] The median filtering unit 131 is configured to perform median filtering on images of tissues that do not contain other tissues inside, and input the processed images to the three-dimensional reconstruction unit 135 .
[0143] The three-dimensional reconstruction unit 135 performs three-dimensional reconstruction according to the tissue filtered by the median filter unit 131 and the tissue processed by the morphology processing unit 124 .
