Abstract

The invention discloses a method for representing a residual liver proportion in a liver resection operation. The method comprises the following steps of Step 1, performing multi-layer scanning on a human liver part through X-ray medical auxiliary equipment to obtain multi-layer CT data of the liver; Step 2, importing the CT data into a software, and converting the CT data into three-dimensional parameters of the liver stereoscopic model by the software; Step 3, fitting the converted three-dimensional parameters of the liver three-dimensional model to generate a liver three-dimensional model, and meanwhile, performing multi-section partitioning on the liver three-dimensional model by means of a partitioning function and completing partitioning calibration; and Step 4, determining a liver resection plan scheme according to the lesion position, completing simulated resection in the liver three-dimensional model by means of a software, then completing calculation of the residual liver proportion through a region calculation function, and evaluating the feasibility of the resection scheme through calculation. Reconstruction of a liver model and characterization of the residual liver proportion are realized by combining a region calculation function and a liver eight-section partition recognition function and embedding a Mimics software.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a method for characterizing the proportion of remnant liver in hepatectomy. Background technique [0002] The 3D reconstruction and visualization module of Mimics allows the surgeon to browse the thin-slice CT volume data set in three orthogonal planes, and can repeatedly observe the region of interest; further perform 3D reconstruction of the region of interest, and the reconstructed model can be arbitrarily Combined display, observation from any angle, adjustable transparency and pseudo-color annotation, so as to clearly show the spatial and three-dimensional positional relationship of the local anatomy; further, the geometric parameters (length, area and volume, etc.) of the region of interest can be measured . Through these observations, Mimics software can help surgeons form a complete, clear and accurate three-dimensional impression of the lesion. Couinaud's ...
