Abstract

The invention provides a lumbar vertebra segment internal fixation mode simulation method and system based on deep learning. The method comprises the following steps: acquiring a CT lumbar vertebra segment scanning image; segmenting the obtained CT lumbar vertebra segment scanning image to obtain a vertebral body structure image; reconstructing a three-dimensional vertebral body model based on the segmented vertebral body structure and carrying out preprocessing; on the basis of the preprocessed three-dimensional vertebral body model, adding and assembling lumbar vertebra segment components to obtain a fixed three-dimensional lumbar vertebra segment model; on the basis of the three-dimensional lumbar segment model, carrying out grid division on the components of the model; carrying out finite element analysis on the basis of the three-dimensional lumbar segment model subjected to grid division to obtain a simulation result of a lumbar segment internal fixation mode; according to the method, the deep learning U-Net network is used for segmenting the image, the current situation that image annotation is troublesome and laborious is improved to a great extent, and a more accurate three-dimensional vertebral body model can be obtained.

Description

technical field [0001] The invention belongs to the technical field of image processing and biomechanical simulation, and in particular relates to a deep learning-based simulation method and system for the internal fixation of lumbar vertebrae segments. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Spinal diseases include degenerative diseases of the lumbar spine, deformities, fractures, tumors, etc., and the onset patients are getting younger and younger, and they are common in the L4-L5 lumbar vertebrae. The clinical manifestations of patients are mostly pain in the lumbosacral region, lower limb pain caused by implication, and inability to stand upright. At present, for this disease, the clinical treatment mostly adopts internal fixation through "minimally invasive surgery", generally pedicle internal fixation and CBT internal fixati...
