Method for representing residual liver proportion in liver resection operation

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 ...

Problems solved by technology

However, there is a high risk in this method. The liver disease can only be analyzed and diagnosed by doctors combined with two-dimensional CT data and clinical experience, and there is no reliable basis for consideration of the surgical plan, which greatly increases the risk of surgery and causes harm to patients. great medical risk
