Embodiment Construction
[0046] This embodiment is realized in a computer whose CPU is Intel(R) Core?? i3-2100 3.10GHz and internal memory is 2.0GB, the programming language is C++, and the three-dimensional visceral CT image to be segmented, such as figure 2 The original abdominal CT image of a patient to be segmented is as follows:
[0047] A segmentation method of viscera and its internal blood vessels in the surgical planning system, which is carried out directly on the running computer. First, the three-phase image of the patient's original CT scan is read into the system, and the three-dimensional visceral CT image and its internal organs are based on the minimum supervised classification. Tubular tissue, formulate the image segmentation method of liver parenchyma, portal vein and hepatic vein, which applies statistical and spatial information methods, introduces high-confidence points and gray-scale-based fast-moving arrival time, and obtains segmentation results, according to the following ste...
