High-resolution x-ray 3D imaging of bone micro-structure
Osteoporosis impact on public health is sharply increasing justifying a significant effort to diagnose, reat and understand this disease. Bones have been imaged with x-rays for almost a century and the basic technology for clinical image is well established, but with the recent development of large scale synchrotron light sources and high-end microfiches x-ray generators, imaging of the intricate bone inner structure with a few micron resolution become possible. Laser driven betatron x-ray microscope was built and used to demonstrate the feasibility of high-resolution bone imaging in the Astra-Gemini laser facility (UK). A sample of femur trabecular bone was imaged from multiple angles and a 3D model of the bone was built using tomographic techniques to a resolution below 50 micron. This demonstration renew the interest in the development of compact laser-plasma electron accelerators and its applications. It also opens prospects for its use in clinic diagnostics in the medium term.
Welcome to the website of the X-GoLP team, the experimental team of the Group for Lasers and Plasmas of the Instituto de Plasmas e Fusão Nuclear at Instituto Superior Técnico.
X-GoLP member João MD participated in a fact checking TV show last week to explain instant ice formation, a popular phenomenon in recent social media videos. In this news clip (in Portuguese), recorded in the laboratory of experimental physics at Técnico, João MD shows that this is a common and well understood phenomenon.
On June 16, the General Assembly of the Extreme Light Infrastructure European Research Infrastructure Consortium (ELI ERIC) appointed X-GoLP member Marta F as member of its International Scientific and Technical Advisory Committee (ISTAC) for a period of three years. The ISTAC members appointed by the General Assembly are high-level personalities internationally recognized for their scientific and technical expertise in the scientific…
