The most frequent head injuries are due to traffic accidents (60-80%). Injuries of skull and consequently the brain under extreme dynamic load is a complex problem whose solution requires a comprehensive analysis on the basis of the biomechanics of a traumatic event.
This study was carried out to describe deformation processes leading to cranial injuries, e.g. in road accidents. The research was related to sustainable human mobility, which is inevitable for the individual’s well being after serious illness or as a result of an accident, e.g. a road accident. The research can be divided into 4 subdivisions: Implementation of algorithms enabling automatic creation of geometric models out of CT or MRI image series.
The project went through following phases:
- Formation of traffic accidents database dealing with the location of frequent collisions, estimation of the degree of consequences severity, clinical specimen on types, scope of injury, and the result of treatment.
- Statistic data processing aimed at formation of database of classified fundamental material for problem solving of bio-mechanic nature.
- Evaluation of statistical solutions of skull damage due to injuries.
The project has following results:
- Production of a calculation of mathematical models within the biomechanics of a human on the CT, MRI, eventually US basis. Application of algorithms for the computer graphics automatic segmentation, surface reconstruction of the injured body parts, optimisation of network for the application of the finite element method.
- Development of methods for a more accurate classification of mechanical characteristics of human tissues, and explanation of biomechanical processes in the conditions of extreme loading
Research of the impact load influence on the human head by means of spatial models will allow a specification of the influence of extreme loads, as well as the analysis of malformation processes of the skull from its start till its damage. Investigation of the impact wave propagation will be needed, both in the skull and soft tissues of the head, especially the brain, together with the modelling of patterns to specify the degree of brain damage.
