With the goal of developing an accurate, powerful and fast method to automate the ana-lysis of bone strength, scientists of the ETH Zurich Departments of Mechanical and Pro-cess Engineering and Computer Science teamed up with supercomputing experts at IBM’s Zurich Research Laboratory. The breakthrough method developed by the team combines density measurements with a large-scale mechanical analysis of the inner-bone microstructure. Using large-scale, massively parallel simulations, the researchers were able to obtain a dynamic “heat map” of strain, which changes with the load applied to the bone. This map shows the clinician exactly where and under what load a bone is likely to fracture. “With that knowledge, a clinician can also detect osteoporotic damage more precisely and, by adjusting a surgical plate appropriately, can...
