Abstract

The invention discloses a spine model construction method and device and a storage medium, and the method comprises the following steps: obtaining a spine CT image, and obtaining a motion simulation result of an experiment model; generating a finite element model according to the spine CT image; simulating the finite element model to obtain a simulation result; carrying out sensitivity analysis according to a simulation result; and adjusting the finite element model according to the sensitivity analysis result and the motion simulation result to obtain a calibration model. According to the invention, the finite element model is generated according to the spine CT image; simulation and sensitivity analysis are carried out, and the finite element model is adjusted according to the motion simulation result and the sensitivity analysis result obtained after motion simulation is carried out on the experimental model to obtain the calibration model, so that the calibration model can fully reflect the influence of the dynamic load under the motion condition, and can be well suitable for the dynamic load condition. The method can be widely applied to the technical field of spine models.

Description

technical field [0001] The invention relates to the field of spine models, in particular to a construction method, device and storage medium of a spine model. Background technique [0002] As an important part of the human skeleton, the spine plays an important mechanical role in maintaining normal physiological activities, bearing various loads, protecting the nerve center, and maintaining various sports postures. Due to the importance of the spine and the diversity and high incidence of spinal diseases, the study of spine biomechanics has always been one of the hotspots of contemporary scholars. The human spine is a unique and complex structure characterized by complex anatomy, inhomogeneous material composition, nonlinear material behavior, etc. Therefore, spine biomechanics is a challenging research field with many obstacles. At present, the construction method of the spine model is usually based on the finite element method, and the established spine model is only limi...
