The damage due to these events can easily lead to catastrophic consequences such as paraplegia or death. In short, there is still a need to better understand the mechanical behavior of the cervical spine. In this paper, a three dimensional finite element model of the head-neck complex is described, which is currently under development. The model consists of the cranium (C0), the seven cervical vertebrae (C1-C7), ligaments of the upper as well as the lower cervical spine, and most of the muscles that provide stability and mobility for the head. Moreover, elastic supports are also incorporated, which will play a significant role in modeling the thorax. The results inform us that the model response might be stiffer than what is expected from a healthy cervical spine. However, there is a good agreement in a qualitative sense since the finite element model exhibits neutral and elastic zones described in the literature.}, year = {2022}, pages = {2495-2501}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:32751450, title = {The Fracture of the Human Cervical Spine}, url = {https://m2.mtmt.hu/api/publication/32751450}, author = {Danka, Dávid and Bojtár, Imre}, doi = {10.17489/2021/2/03}, journal-iso = {BIOMECH HUNG}, journal = {BIOMECHANICA HUNGARICA}, volume = {14}, unique-id = {32751450}, issn = {2060-0305}, year = {2021}, eissn = {2060-4475}, pages = {31-41}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:31815705, title = {Evaluation of Brain Injury Criteria Based on Reliability Analysis}, url = {https://m2.mtmt.hu/api/publication/31815705}, author = {Hazay, Máté and Bojtár, Imre}, doi = {10.37190/ABB-01755-2020-04}, journal-iso = {ACTA BIOENG BIOMECH}, journal = {ACTA OF BIOENGINEERING AND BIOMECHANICS}, volume = {23}, unique-id = {31815705}, issn = {1509-409X}, year = {2021}, pages = {173-185}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:31815699, title = {Engineering optimization of decompressive craniectomy based on finite element simulations}, url = {https://m2.mtmt.hu/api/publication/31815699}, author = {Hazay, Máté and Nagy, Emese and Tóth, Péter József and Büki, András and Bojtár, Imre}, doi = {10.37190/ABB-01689-2020-03}, journal-iso = {ACTA BIOENG BIOMECH}, journal = {ACTA OF BIOENGINEERING AND BIOMECHANICS}, volume = {22}, unique-id = {31815699}, issn = {1509-409X}, year = {2020}, pages = {109-122}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:30635242, title = {The Probability of Traumatic Brain Injuries Based on Tissue-level Reliability Analysis}, url = {https://m2.mtmt.hu/api/publication/30635242}, author = {Hazay, Máté and Dénes, Dániel and Bojtár, Imre}, doi = {10.5277/ABB-01281-2018-02}, journal-iso = {ACTA BIOENG BIOMECH}, journal = {ACTA OF BIOENGINEERING AND BIOMECHANICS}, volume = {21}, unique-id = {30635242}, issn = {1509-409X}, year = {2019}, pages = {141-152}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:30388205, title = {OPTIMIZATION OF DECOMPRESSIVE CRANIECTOMY BASED ON FINITE ELEMENT SIMULATIONS}, url = {https://m2.mtmt.hu/api/publication/30388205}, author = {Hazay, Máté and Bakos, Bernadett and Tóth, Péter József and Büki, András and Bojtár, Imre}, doi = {10.14311/APP.2018.18.0006}, journal-iso = {ACTA POLYTECH CTU PROC}, journal = {ACTA POLYTECHNICA CTU PROCEEDINGS}, volume = {18}, unique-id = {30388205}, abstract = {Decompressive Craniectomy (DC) is a neurosurgical procedure which is often applied to decrease the intracranial pressure (ICP), even if its optimal execution in terms of the size and location of the skull opening is not known. The current research focuses on DC from a biomechanical perspective. A finite element (FE) modelling strategy is applied where patient-specific head models are developed. These numerical models are used to perform virtual experiments where DC is simulated several times with skull openings having different size and location. During the simulations ICP, stress and strain distributions in the brain tissue are monitored in the function of the skull opening details. In the knowledge of these objective functions suggestions could be made regarding the applied optimization procedure which can lead to the identification of optimal DC scenarios in the future.}, keywords = {Intracranial Pressure; Numerical simulations; patient-specific head models}, year = {2018}, eissn = {2336-5382}, pages = {6-9}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:3423804, title = {Finite element reconstruction of decompressive craniectomy}, url = {https://m2.mtmt.hu/api/publication/3423804}, author = {Hazay, Máté and Varga, Annamária and Nagy, Eszter and Tóth, Péter József and Büki, András and Bojtár, Imre}, doi = {10.17489/2018/2/08}, journal-iso = {BIOMECH HUNG}, journal = {BIOMECHANICA HUNGARICA}, volume = {11}, unique-id = {3423804}, issn = {2060-0305}, year = {2018}, eissn = {2060-4475}, pages = {51-60}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:3296897, title = {Impact biomechanics of brain injuries: a proposal for evaluating vulnerability based on reliability analysis}, url = {https://m2.mtmt.hu/api/publication/3296897}, author = {Hazay, Máté and Bojtár, Imre}, doi = {10.17489/biohun/2017/1/08}, journal-iso = {BIOMECH HUNG}, journal = {BIOMECHANICA HUNGARICA}, volume = {10}, unique-id = {3296897}, issn = {2060-0305}, year = {2017}, eissn = {2060-4475}, pages = {75-84}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} } @article{MTMT:3226420, title = {Gerendamodellek összehasonlítása}, url = {https://m2.mtmt.hu/api/publication/3226420}, author = {Hazay, Máté and Bojtár, Imre}, doi = {10.1556/096.2017.45.1-2.8}, journal-iso = {ÉPÍTÉS-ÉPÍTÉSZETTUDOMÁNY}, journal = {ÉPÍTÉS-ÉPÍTÉSZETTUDOMÁNY}, volume = {45}, unique-id = {3226420}, issn = {0013-9661}, year = {2017}, eissn = {1588-2764}, pages = {117-138}, orcid-numbers = {Bojtár, Imre/0000-0002-0148-9499} }
