The density of bone is subject to change due to natural causes or bone abnormalities and disorders such as osteopenia, osteomalacia and osteoporosis. One of the most concerning attributes of osteoporosis is its non-expressive nature, which means it is more often than not diagnosed after it causes a bone fracture. Recent technological advancements have enabled digital reconstruction of bone via imaging...
Realistic surgical simulation should take into account the mechanical properties of soft tissue, and also patient-specific variations. Consequently automated methods are required for the acquisition and modeling of patient-specific tissue properties.We take a step toward this goal by presenting a semiautomated method for acquiring, modeling, and simulating soft-tissue deformation. During a typical...
Differences in the dynamics of powder densification between eccentric and rotary machine were pointed out by compressing at different compression pressures microcrystalline cellulose, lactose monohydrate and dicalcium phosphate dihydrate and recovering the corresponding stress/strain data in both machines equipped to monitor punches displacement and compression forces. Heckel plots were then obtained...
