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

Abstract

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 is carried out on the segmented liver, the liver segments with abnormal drainage basins are obtained, and determination and accurate implementation of a liver operation scheme are facilitated. Therefore, the operation time and cost can be saved, and pain of a patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, in particular to a liver segmentation system based on watershed analysis and an operation method thereof. Background technique [0002] Liver segmentation is an effective method for localizing liver tumors and the basis of precise liver resection. There are many liver segmentation methods, but there is no consistent conclusion on liver segmentation in the medical community. At present, Couniaud liver segmentation is the most common liver segmentation in clinical practice. Segment method, which divides the liver into 8 segments, is widely used, but in actual clinical practice, due to the complex and changeable intrahepatic blood vessels, there are great individual differences in the spatial distribution of the portal vein and its 3-4 grade vessels, and the variation of the portal vein Very common, the division by Couinaud's segmentation method does not fully conform to the actual ...

[0002] Liver segmentation is an effective method for localizing liver tumors and the basis of precise liver resection. There are many liver segmentation methods, but there is no consistent conclusion on liver segmentation in the medical community. At present, Couniaud liver segmentation is the most common liver segmentation in clinical practice. Segment method, which divides the liver into 8 segments, is widely used, but in actual clinical practice, due to the complex and changeable intrahepatic blood vessels, there are great individual differences in the spatial distribution of the portal vein and its 3-4 grade vessels, and the variation of the portal vein Very common, the division by Couinaud's segmentation method does not fully conform to the actual distribution of intrahepatic ducts, and does not quite match the actual patient situation. It is too simplistic, has insufficient and inevitable limitations, and cannot meet the current medical clinical requirements.
