Model-based inverse problem: Estimation of the cortical thickness and porosity of long bone using ultrasonic guided waves

Speaker:Dr. Nicolas Bochud (UPMC)

Place: Room 521, Physics Building, Handan Campus

 

 

Abstract

This seminary presents the last advances of our research team on the in vivo cortical bone characterization using ultrasonic guided waves. A first part focuses on the inverse procedure used to retrieve the cortical bone properties, whereas a second part introduces an anisotropic bilayer model to account for the soft tissue.

 

 

Biography

Nicolas Bochud was born in Winterhtur, Switzerland, in 1983. He holds a PhD in Structural Mechanics from the University of Granada, Spain, in 2014. He previously received a MsC Degree in Mechanical Engineering from the Swiss Federal Institute of Technology (ETH), Zurich, in 2008, and a MsC Degree in Information Technology from the University of Granada, in 2010. He is currently continuing his career as a post-doctoral researcher at the Laboratoire d’Imagerie Biomedicale, UPMC-CNRS-INSERM, Paris, where he works on the assessment of the geometrical and elastic properties of cortical bone using ultrasonic guided waves. His research field includes ultrasonic nondestructive evaluation of complex materials, signal processing and modeling of ultrasonic signals, optimization and inverse problems.
