Besides being biocompatible and biodegradable, these microspheres exhibit acoustic enhancements that make them useful as contrast agents for diagnostic imaging using ultrasound. Moreover, they are very stable and give a prolonged acoustic enhancement, as compared to other ultrasound contrast agents.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

Without adequate head movement control, efficient special orientation and motor responses to visual and auditory stimuli could not be carried out. In order to fully understand and predict the head trajectory in the 3-dimensional space, three-dimensional and mathematical models of the head-neck system were developed. The mathematical model was used in the simulation process. This project is an effort to take a two-dimensional head rotation model of the head-neck system, which was described by many authors and researches in various forms, to three-dimensional movement.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

This device utilizes inertial loads created by a weighted shuttle (22.2 N) traveling on a rail system and assimilates repetitive concentric-acceleration and eccentric-deceleration throughout the exercise. In the current study, the objective was to quantify the shoulder joint mechanics resulting from this instrumented exercise system when used as a rehabilitative tool. Inverse dynamic relationships were used to quantify the forces and moments acting on the shoulder joint throughout the exercise. Work and power were also compared between shoulder function and shuttle motion.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.
