A novel computational model of the wrist that predicts carpal bone motion was developed in order to investigate the complex kinematics of the human wrist. This rigid body spring model (RBSM) of the wrist was built using surface models of the eight carpal bones, the bases of the five metacarpal bones, and the distal parts of the ulna and radius, all obtained(More)
The purpose of this study was to compare computed tomography density (ρCT ) obtained using typical clinical computed tomography scan parameters to ash density (ρash ), for the prediction of densities of femoral head trabecular bone from hip fracture patients. An experimental study was conducted to investigate the relationships between ρash and ρCT and(More)
The recently introduced Canadian Engineering Accreditation Board (CEAB) requirements for Graduate Attributes [1] require demonstrated learning outcomes for the first time. CDIO has required outcomes and benchmarking for more than a decade, and the CDIO Syllabus [2] has provided a detailed and proven framework within which to organize the topics covered by(More)
OBJECTIVE To examine the geometry of the proximal isovelocity surface area (PISA) envelope and its associated isotach, and to evaluate the accuracy of two models of calculating volumetric flow by using the PISA technique. DESIGN A new model for determining isotach geometry from the PISA envelope was developed and tested in an in vitro simulation. (More)
