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.

目前，无法监测脊柱对物理载荷的3D机械响应，并且脊柱支具过程的发展缓慢。本研究旨在调查，推进和集成监测技术（传感器和执行器），特别是实时3D超声图像处理技术，3D无线空间嵌入式压力控制传感器网络，以及低成本高速3D形状采集过程，以调查模拟脊柱支具施加的生物力学载荷如何影响脊柱内部对齐。将完成四项任务：1）研究用于实时显示的3D超声诊断技术，2）开发原型并验证具有已知几何形状的物理脊柱模型上的3D超声测量，3）开发并验证空间压力监测系统以记录施加到身体模型的压力垫的负载、位置和方向，以及4）开发高速自动过程以使用低成本相机系统来捕获3D身体形状。
