Embodiment Construction
[0044] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe in detail the embodiments of the present invention in conjunction with the accompanying drawings.
[0045] Embodiments of the present invention provide a method for segmenting biliary tract images, such as figure 1 As shown, the method can include:
[0046] Step 101. Receive a starting pixel point selection instruction, the starting pixel point selection instruction is used to instruct to determine at least one pixel point in the medical image as the starting pixel point for searching the medical image.
[0047] Step 102, searching in the medical image based on each starting pixel point.
[0048] Step 103, when searching in the neighborhood of the target pixel, determine the energy value of each pixel in the neighborhood of the target pixel based on the pipeline coefficient of the pixel in the medical image.
[0049] Among them, the pipe...

The invention discloses a bile duct image segmentation method, a terminal and a storage medium and belongs to the field of medical image processing. The method comprises the following steps: receivinga start pixel point selection instruction to determine at least one pixel point in a medical image as a start pixel point for searching the medical image; based on each start pixel point, carrying out searching in the medical image; when searching in the neighborhood of a target pixel, determining an energy value of each pixel in the neighborhood of the target pixel based on the duct coefficientof the pixel points in the medical image, wherein the duct coefficient is used for reflecting duct shape features of a preset medical image area where a first pixel point is located; based on the energy value of each pixel, determining pixel points to be selected in the medical image; and determining the image areas represented by all of the pixel points to be selected in the medical image as segmented bile duct areas. The method improves accuracy of the bile duct image obtained after segmentation, and is used for segmenting the bile duct image.
Description
technical field [0001] The present invention relates to the field of medical image processing, in particular to a biliary tract image segmentation method, terminal, and storage medium. Background technique [0002] Image segmentation of medical images such as computed tomography (CT) images to obtain clear biliary tract images in medical images is of great significance for the diagnosis, treatment and surgical planning of biliary tract diseases. [0003] At present, in the field of medical image processing, the most commonly used biliary tract image segmentation methods are region growing algorithm, matched filter method, centerline-based method, active contour method and statistical-based method, etc. Among them, the region growing algorithm is based on the pixel value of the preset seed point as the standard, and when the relationship between the pixel value of the pixel point and the pixel value of the seed point satisfies the preset growth rule, the corresponding pixel p...
