An afternoon talk on femurs, arteries and high order finite element methods
Prof. Zohar Yosibash
School of Mechanical Engineering, Tel Aviv University
Predicting the mechanical response of human femurs and arteries is of major clinical importanceare for diagnostic purposes as well as for patient-specific treatment. Such prediction capabilities are being described which involve the combination of high order finite element (FE) methods, medical imaging and experimental observations.
Our research on human femurs will first be addressed, where we use quantitative computerized tomography (qCT scans) that enables a computer realization of subject-specific bone models. Combining qCT scans with high order FE simulations and a large set of experiments provide the opportunity to accurately simulate patient-specific femur’s response, allowing orthopedic surgeons to plan a proper patient specific treatment. Examples of the use of our methods in clinical practice for treatment of metastatic bone tumors will be provided.
If time allows, experimental and numerical methods for the analysis of human arteries will be addressed. Arteries are complex anisotropic structures undergoing large deformations and strains and are subject to active response due to contraction of smooth muscle cells. Attempts to properly describe their response will be described.
