  • Tissue modeling and analyzing with finite element method: a review for cranium brain imaging.
    International Journal of Biomedical Imaging, 2013
    Co-Authors: Li Wang, Ruonan Wang
    Abstract:

    For the structure mechanics of human body, it is almost impossible to conduct mechanical experiments. Then the finite element model to simulate mechanical experiments has become an effective tool. By introducing several common methods for constructing a 3D model of Cranial Cavity, this paper carries out systematically the research on the influence law of Cranial Cavity deformation. By introducing the new concepts and theory to develop the 3D Cranial Cavity model with the finite-element method, the Cranial Cavity deformation process with the changing ICP can be made the proper description and reasonable explanation. It can provide reference for getting cranium biomechanical model quickly and efficiently and lay the foundation for further biomechanical experiments and clinical applications.

  • study on the matrix and stress strain relationship of laminated structure in the Cranial Cavity with the changing intraCranial pressure
    BioMedical Engineering and Informatics, 2012
    Co-Authors: Li Wang, Ruonan Wang, Hualin Yu
    Abstract:

    Except the blood vessel in-out the Cranial Cavity and basiCranial hole open onto skull, the Cranial Cavity can be totally regarded as one closed container. IntraCranial Pressure (ICP) is fluctuant in brain. The Cranial Cavity will deform with the changing ICP, which is complex questions and can't be solved the analytical solution. As a very effective numerical method, the finite element is used to analyze the deformation of Cranial Cavity. Cranial Cavity is the hollow sphere formed by the skull and the duramater. There are obvious interfaces among the various parts of outer compact bone, middle cancellous bone, inner compact bone and duramater. In this paper, the matrix of laminated structure and stress-strain relationship of laminated structure have been set up in the Cranial Cavity, which will be the foundation to analyze the actual deformation of human skull-duramater system with the finite-element software.

  • Potential therapeutic actions of hypothermia: Finite-element simulation of human skull deformation with hypothermia treatment
    2010 3rd International Conference on Biomedical Engineering and Informatics, 2010
    Co-Authors: Ruonan Wang, Li Wang
    Abstract:

    OBJECTIVE: A quantitative effect of the hypothermia treatment was made on the Cranial-Cavity deformation with the increasing intraCranial pressure (ICP). METHORDS: Finite element software-ANSYS was used to construct a human Cranial Cavity model, and simulate the deformations with and without hypothermia treatment. RESULTS: The deformation of the Cranial-Cavity model with hypothermia treatment is 0.56% less on average than the results without hypothermia treatment. CONCLUSION: The influence of hypothermia on the Cranial-Cavity deformation should be considered in clinical situations.

    Abstract:

    Purpose In addition to the optic canal and the superior orbital fissure, orbits are connected with the Cranial Cavity via inconstant canals including the orbitomeningeal foramen.

    Abstract:

    Purpose In addition to the optic canal and the superior orbital fissure, orbits are connected with the Cranial Cavity via inconstant canals including the orbitomeningeal foramen. This study has been carried out in order to define many anatomical and radiological details of the orbitomeningeal foramen that are relevant in the clinical practice. Methods Almost 1000 skulls and 50 computerized tomographies were examined to determine incidence, number, length, and caliber of the orbitomeningeal foramen as well as the topography of their orbital and Cranial openings. A retrospective study of angiographies carried out on more than 100 children was performed to look for arteries candidate to run through the orbitomeningeal foramen. Results Orbitomeningeal foramina were detected in 59.46 % of skulls and in 54 % of individuals by computerized tomography. Orbits with two to five foramina were found. Canals were classified as M-subtype or A-subtype depending on their Cranial opening. Large foramina, with the caliber ranging between 1 and 3 mm, were found in 12.17 % of orbitomeningeal foramen-bearing orbits. By computed tomography the average caliber measured 1.2 ± 0.3 and 1.5 ± 0.5 mm ( p
