Shoulder anatomy size varies significantly when human weight changes from 120lb to more than 400 lb. This rather a huge “shoulder geometry” variation presents a technical challenge to shoulder coil design with respect to coverage and SNR, yielding a conventional approach where a large shoulder coil and a small shoulder coil are offered. Previous studies show that hinged surface coil gave a high...

This paper describes a simple, yet efficient method for modelling complex musculo-skeletal structures in motion. The proposed approach contains three main modules: segmentation, 3D reconstruction, and feature extraction. The segmentation module integrates region and edge information in a coherent manner. The 3D reconstruction technique is based on morphological morphing between adjacent slices ...

Seat belt interaction with a far-side occupant's shoulder and thorax is critical to governing excursion towards the struck-side of the vehicle in side impact. In this study, occupant-to-belt interaction was simulated using a modified MADYMO human model and finite element belts. Quasi-static tests with volunteers and dynamic sled tests with PMHS and WorldSID were used for model validation and co...

We propose a web application based security system. When a user interacts with a computing system to enter a secret password, shoulder surfing attacks are of great concern. This system overcomes the problem of shoulder surfing. Previous system proposed a methodology in which the user has to remember all the events performed. This limits the system usage. Our novel approach enhances the shoulder...

The activity of motor cortical cells and proximal arm muscles during the initiation of planar reaching movements were analyzed to identify whether features of coordinated motor patterns of muscles spanning the elbow and shoulder were evident in the discharge patterns of motor cortical cells. Shoulder and elbow muscles were divided into four groups, flexors and extensors at each joint. Features ...

Introduction: The tensile properties of the shoulder ligaments under dynamic loading have not been investigated. A recent finite element model showed the ligaments in the shoulder were subjected to dynamic tensile loading during 8.65 m/s lateral shoulder impact [1]. The mechanical properties of shoulder joints under dynamic loading are needed to better understand shoulder injury mechanisms, to ...
