Embodiment 1

[0031] This embodiment provides a method for reconstructing a defective tongue after tongue cancer surgery, including:

[0032] Through 3D reconstruction to obtain the 3D surface mesh model of the tongue;

[0033] On the surface of the resection area in the three-dimensional surface mesh model of the tongue body, select several mark points for fitting the curved surface of the defective tongue; the several mark points include the lowest point of the resection area, the highest point of the resection area, the resection Two marker points on the frontal zone boundary of the region, one marker point on the side zone boundary of the resection zone and one marker point on the back zone boundary of the resection zone;

[0034] Based on the selected marker points, fit the surface of the resection area;

[0035] unfolding the surface of the cut-off region to obtain the unfolded surface of the cut-off region;

[0036] Physical parameters of the unfolded surface are measured.

[0037...

Embodiment 2

[0072] The method for reconstructing the defective tongue body after tongue cancer surgery described in this embodiment specifically includes the following steps:

[0073] S11, through 3D reconstruction, to obtain a 3D surface mesh model of the tongue.

[0074] Specifically, the tongue body area in the CT medical image is extracted, and a three-dimensional surface mesh model of the tongue body is obtained through three-dimensional reconstruction.

[0075] S12. Selecting 6 marker points for fitting the curved surface of the defective tongue on the surface of the resection area in the three-dimensional surface mesh model of the tongue. In this embodiment, the resection area of ​​the tongue is divided into front, side and back. The several mark points include the lowest point of the cut-off area, the highest point of the cut-off area, two mark points on the front area boundary of the cut-off area, a mark point on the side area boundary of the cut-off area and a point on the back...

Embodiment 3

[0101] This embodiment provides a system for reconstructing the defective tongue after tongue cancer surgery, please refer to Figure 5 , which is a schematic diagram of the principle structure of a system for reconstructing a defective tongue after tongue cancer surgery in an embodiment. Such as Figure 5 As shown, the tongue defect reconstruction system 5 after tongue cancer surgery includes: a modeling module 51 , a selection module 52 , a curved surface fitting module 53 , a developed surface fitting module 54 and a measurement module 55 .

[0102] The modeling module 51 is used for obtaining a three-dimensional mesh model of the tongue through three-dimensional reconstruction.

[0103]The selection module 52 is used to select a number of marker points for fitting the curved surface of the defective tongue on the surface of the resection area in the three-dimensional surface mesh model of the tongue; the number of marker points include the lowest point of the resection ar...

Abstract

The invention provides a tongue cancer postoperative defect tongue body reconstruction method and system, a readable storage medium and equipment, and the reconstruction method comprises the steps: obtaining a tongue body three-dimensional surface grid model through three-dimensional reconstruction; selecting mark points on the surface of the cutting area in the three-dimensional surface grid model of the tongue body, wherein the mark points comprise the lowest point of the cut-off area, the highest point of the cut-off area, two mark points on the front area boundary of the cut-off area, the mark points on the side area boundary of the cut-off area and the mark points on the back area boundary of the cut-off area; on the basis of the selected mark points, fitting a curved surface of the cut-off area; unfolding the curved surface of the excision area to obtain an unfolded surface of the excision area; and measuring the physical parameters of the unfolded surface. According to the invention, the mark points are taken from the reconstructed tongue model, the fitting surface of the resection range of the tongue body is established, and the fitting curved surface is extended into a plane to obtain the area and the contour range of the skin flap to be resected, so that the planning is more consistent with the individualization, and the failure rate of the operation is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and relates to a reconstruction method and system, in particular to a method, system, readable storage medium and equipment for reconstructing a defective tongue after tongue cancer surgery. Background technique [0002] Tongue cancer is the most common oral cancer. After resection, it often causes large-scale defects, which seriously affects the patient's language, swallowing and chewing functions, and the quality of life is significantly reduced. Therefore, how to repair the defect of tongue cancer and restore the shape and function of the patient's tongue to the greatest extent is the key to improving the quality of life of the patient. [0003] In the late 1970s, due to the continuous development of maxillofacial plastic surgery, especially microsurgery, a new approach was opened up for the reconstruction of tongue cancer after resection. Vascularized free skin such as forear...
