Embodiment Construction
[0013] The specific steps of the method of the present invention are as follows: (1) Acquire medical original images. (2) The image is preprocessed and segmented. (3) Extract the surface of the inner wall of the organ. (4) Extract the valgus reference plane. (5) Perform valgus processing on the surface data of the inner wall of the organ. (6) Interactive display. The technical solution of the present invention will be further described in detail below in conjunction with a specific embodiment.
[0014] This embodiment uses the human colon as a sample for visualization reconstruction. The realization process of whole invention is as follows:
[0015] 1. Perform CT imaging on the lower abdomen of the human body to obtain CT tomographic image data.
[0016] 2. Perform necessary filtering processing on the tomographic image, including Gaussian filtering and median filtering, to remove noise.
[0017] Using the region growing algorithm, the cavity inside the colon is segment...
