Liver segmentation system based on drainage basin analysis and operation method thereof

The liver segmentation system based on drainage basin analysis comprises a data receiving module, an image reading module, an image extraction module, an image processing module and an image analysis module; the image processing module comprises an image selection sub-module, an image editing sub-module and an image rendering sub-module, the image selection sub-module and the image editing sub-module carry out segmented processing on hepatic portal vein blood vessels, and the image rendering sub-module renders livers corresponding to the segmented hepatic portal vein blood vessels into different colors, thereby forming segments of the liver; and the image analysis module is used for carrying out segmented drainage basin analysis on the segmented liver. Compared with the prior art, accurate and personalized liver segmentation can be carried out according to portal vein space distribution condition characteristics of different patients, the segmentation result is accurate and objective, drainage basin analysis
