Ultrasonic assessment of cortical bone.

Contacts : Maryline Talmant, Jean-Gabriel Minonzio, Quentin Grimal, Pascal Laugier.

Different types of guided waves can propagate in cortical (or compact) bone. The analysis of these waves can provide information such as structural (cortical thickness, porosity) and material properties (elasticity, density). From the clinical perspective, this information is relevant for fracture risk assessment. This research topic is supported by innovative axial transmission technologies developed for the clinical use, associated with original signal processing methods allowing the extraction, identification and exploitation of several ultrasound propagation modes. Current research orientations include development of numerical models coupled to experimental data and solutions to inverse problems. Patents on transducer arrays dedicated to long bone cortical shell evaluation using bi-directional transmission have been registered.
