In order to establish the finite element model of the knee-joint, force analysis applies on the knee-joints of persons are done first. The CT scanning images of a normal male volunteer's upper end of tibia are adopted, which are processed by Mimics 13.0 software to calculate a 3D model. Surfaces of the model are dealt by Geomagic 9.0 software and a smooth shell model is constructed. At the same time,...
The 4D extended cardiac-torso (XCAT) phantom was developed to provide a realistic and flexible model of the human anatomy and cardiac and respiratory motions for use in medical imaging research. A prior limitation to the phantom was that it did not accurately simulate altered functions of the heart that result from cardiac pathologies such as coronary artery disease (CAD). We overcame this limitation...
Create a biological modeling of human lower limb is a difficult job due to the complex and irregularity skeleton structure. However, rebuilding the model that can be used to calculate the biomechanics characteristic is the key step to research the human body. Reverse engineering should be used in rebuilding model. The model consists of at least lower limb skeleton and joint cartilage. Cartilage is...
Dental implantation to a certain extent changes the biomechanical environment, thereby leading to the surrounding supporting bone to remodel. Computational remodeling has been well established in lone bone community and a range of mathematical formulae have been available with acceptable accuracy and effectiveness. However, there has been limited information and remodeling data available for dental...
The mechanical properties of bone depend on the material assignment in mechanical finite element (FE) analysis. The aim of this study is to investigate the differences of mechanical properties of femur using two material assignment methods. The CT data of bone were used in both methods. The three-dimensional FE model was also established based on the femur CT data and the physiologic loads were applied...
