3D Ultrasound Imaging and Spatial Pressure Measurement System to Investigate Spinal Curve Response Imposed by a Simulated Brace

Currently, the 3D mechanical response of the spine to physical loadings cannot be monitored and the development of the spinal brace process is slow. This research aims to investigate, advance and integrate monitoring technologies (sensors and actuators), specifically real-time 3D ultrasound image processing techniques, a 3D wireless spatial embedded pressure control sensor network, and a low cost high speed 3D shape acquisition process to investigate how the biomechanical loadings applied from a simulated spinal brace affects the internal spinal alignment. Four tasks will be completed: 1) investigate 3D ultrasound diagnostic technologies for real-time display, 2) develop prototypes and validate 3D ultrasound measurements on a physical spinal phantom with known geometry, 3) develop and validate a spatial pressure monitoring system to record loads, positions and directions of pressure pads applied to a body phantom, and 4) development of a high speed automatic process to capture the 3D body shape using a low cost camera system.
