Dynamic Roentgen stereophotogrammetry Dynamic Roentgen stereophotogrammetry Dynamic Roentgen stereophotogrammetry (also referred to as dynamic RSA) is a modern and sophisticated x-ray recording method, used to measure real-time 3D motions of prostheses and bones during motion with high accuracy. It is mostly used in orthopedic research settings and is an advancement of conventional RSA. Conventional static RSA is used to evaluate migration of prosthesis with respect to the bone in three dimensions as a function of time. Migration of the prosthesis are normal 12‐24 months after the surgery. Ongoing migration increase the risk of aseptic loosening with revision surgery as a consequence. The method
Sanford Burnham Prebys Medical Discovery Institute careers in basic and translational research through a curriculum of focused, multi-disciplinary instruction. In 2015, SBP achieved accreditation with the Western Association of Schools and Colleges. SBP also employs postdoctoral fellows; there are typically around 250 postdocs training at SBP at any time. The endowment was recorded at as low as $15.2 million, a 13 percent drop from nearly $17.5 million in February 2008, due largely to losses on investments. Its endowment stood at $22.5 million as of Dec. 31, 2009.
