Image Processing & Landmarking

      A humerus model was generated from MRI data of a 26yr old healthy male, using the semi-automated segmentation tools available in Simpleware ScanIP. Interactive measure­ment tools allowed for the generation and rapid interactive placement of landmark points, using both 2D and 3D views. Each point could be named and exported with its coordinate values. Finally, high quality surface and volume meshes were generated to allow direct use of load cases computed by AnyBody in subse­quent FE analysis.

Musculoskeletal Modelling

       The bone landmarks generated within Simpleware were then used for generating a subject-specific AnyBody analysis, computing a dynamic physiological load case for the humerus for dumbbell lifting. Output was dynamic individual muscle and joint forces. Input was an average US male body model, a model scaled to match the height and weight of the subject, and the same model also including the subject-specific humerus shape derived from Simpleware. Notice how inclusion of subject-specific data into the model affects the results.
