(stage de Master 2 ou dernière année d’école d’ingénieur)
Date ou durée du stage
- 6 mois
Contexte
A 6-month Master internship is offered at Sorbonne Université (SU, Paris, France; https://www.sorbonne-universite.fr/). The trainee will work at the Laboratoire d’Imagerie Biomédicale (https://134.157.99.81/). He will join the group DBMS (Determinant of Bone Mechanical Status) which is one of the world’s leading groups for the characterization of the mechanical properties of bones with dynamical methods. DBMS has a strong expertise in using ultrasound waves and vibrational methods to characterize bone. The group has recently focused on a new research topic: ultrasound imaging of bone (Renaud et al. Phys Med Biol. 2018). Current medical ultrasound scanners produce excellent images of soft tissues but fail to image bone. We aim to develop ultrasound imaging of bone. If successful it will broaden the range of clinical uses of ultrasonography. The situation is highly similar to marine seismic exploration; indeed the investigated medium contains fluid-like layers (skin, muscle, marrow) and anisotropic solid layers (cortical bone).
Mission(s)
The trainee will work on the characterization of multiple reflections and multiple diffuse scattering in the context of intraosseous ultrasound imaging. These phenomena are not considered by conventional algorithms of image reconstruction and create clutter in the image. The trainee will develop methods to extract and quantify their magnitude. This study will be conducted on synthetic signals created with numerical simulations and on experimental signals acquired on in vitro setups and in vivo with an ultrasound array transducer.
Compétences
- Master students in seismology or physical acoustics will be considered.
- Basic programming skills (Matlab, C++) and writing skills (reports, research articles) are required.
- Excellent level of English is required
Rémunération
- « Gratifications de stage » (Financial conditions follow Sorbonne Université guidelines)
