The International Bone Ultrasound Society Newsletter Summer 2019The 8thInternational Symposium on Ultrasonic Characterization of Bone(ISUCB) was organized in Fréjus, France from June 24 to 26, 2019. About 50 participants presented their latest works on bone ultrasound physics (backscattering, guided waves, piezoelectricity, etc.), bone material characterization, numerical methods, signal processing including the use of artificial intelligence, bone imaging methods, and clinical applications. Six students obtained a travel award and three students were awarded for their excellent presentations at the conference.

Presentation Awards
Fan Fan (5thfrom left, Beihang University, China and Paris, France), Winner, Microstructural and compositional determinants of elastic damping assessed from resonant ultrasound spectroscopy measurements in cortical boneTsukasa Nakamura (6thfrom left Doshisha, Japan), Finalist, Site dependence of ultrasonically induced electrical potentials in boneDongsheng Bi (3rd from left, Fudan University, China), Finalist, machine learning classifier for osteoporosis diagnosis using ultrasonic backscatter signalsDuring the General Assembly, the board of the Society has been re-elected and Jean-Gabriel Minonzio was elected as a new board member.LinkIn 2021, four years after the workshop in Banz (Germany), the 9th ISUCB will be organized jointly with the QMSKI workshop (23rd International Workshop on Quantitative Musculoskeletal Imaging). This will be a fantastic opportunity for the bone ultrasound community to present novel ultrasound technologies to a broader audience, learn from and network with researchers concerned with technologies and scientific findings related to skeletal health.In 2020, BoneUS will prepare a White Paper on bone ultrasound. A dedicated mailing list will be prepared. If you would like to take part this project, or simply to be kept informed, please emailinfo@bone-ultrasound.orgwith subject “2020 White Paper BoneUS”. The White Paper will be a short document (5 pages maximum) intended for funding agencies, clinicians, associations of patients, and researchers. The White Paper will (1) present available technologies to diagnose skeletal diseases and associated main clinical studies; (2) provide a picture of innovative ultrasound approaches and technical challenges; (3) identify key clinical applications; (4) provide recommendations for standardization.A new patent application for the quantitative assessment of cortical bone properties has been published in December 2018 by Dr. Raum and his team from Charité-Universitätsmedizin Berlin. The patent describes backscatter and refraction methods to measure thickness, speed of sound, pore size and density, and porosity in cortical bone.LinkNew reports of clinical studies and recent reviews

Miscellaneous news Bone in Crime ScenesArthur Angermuller (Cergy-Pontoise university, France) investigates how ultrasound measurements of bone could help the police dating bone remnants in crime scene. Arthur was a finalist of the contest “My thesis in 180 seconds” (video in French)A Robot to Diagnose and Treat Bone LossA medical robot from Fudan University (China) uses a device to diagnose bone loss using ultrasonic backscatter and to treat bone loss using low intensity pulsed ultrasound. The device was presented at the international fair of inventions in Geneva and won an Award.LinkGuided waves improve assessment of capillary perfusion in the skeletal muscle near the bone cortex.LinkChameleon Bones Glow in the Dark, Even Through SkinLinkXingxing Chou (Fudan University, China) defended her PhD: “bone evaluation method under microgravity using ultrasonic backscatter”In June 2019, a Ph.D. candidate of Prof. Dean Ta of Fudan University, China, Xingxing Chou passed her doctoral dissertation defense. The thesis is entitled “Bone evaluation method under microgravity using ultrasonic backscatter”. Simulation were performed to investigate the parameter sensitivity of ultrasound backscatter method with cancellous bone microstructural variation. The ultrasound backscattering experiments were carried out with New Zealand rabbits in vivo with different bone loss. The correlation between biochemical parameters of bone metabolism and ultrasonic backscatter parameters was also investigated.Upcoming Conferences October 6 – 9, 2019 IEEE International Ultrasonics SymposiumGlasgow, Scotland, UKNovember 25-27 201940th Symposium on Ultrasonics Electronics, Tokyo, JapanDecember 2-6, 2019178th Meeting of the Acoustical Society of America, San Diego, California, U.S.A.May 11-15, 2020179th Meeting of the Acoustical Society of America, Chicago, Illinois, U.S.A.You are welcome to contribute to the content of this Letter by proposing material such as announcement of conferences; remarkable achievements in the areas of bone metabolism, osteoporosis, ultrasound technologies; calls for projects in the area of bone & ultrasound; new patents; PhD defense; etc.Do you have questions, ideas or news?
