    • A portable measurement system is provided including a probe, a user interface control and a receiver. The probe includes a plurality of ultrasonic transducers that emit ultrasonic waveforms for creating a three-dimensional sensing space. The user interface control captures a location and position of the probe in the three-dimensional sensing space. The receiver includes a plurality of microphones to capture the ultrasonic waveforms transmitted from the probe to produce captured ultrasonic waveforms and a digital signal processor that digitally samples the captured ultrasonic waveforms and tracks a relative location and movement of the probe with respect to the receiver in the three-dimensional ultrasonic sensing space from time of flight waveform analysis. Embodiments are demonstrated with respect to hip replacement surgery, but other embodiments are contemplated.
    • 提供了包括探针,用户界面控制和接收器的便携式测量系统。 探针包括发射超声波形以产生三维感测空间的多个超声换能器。 用户界面控制在三维感测空间中捕获探针的位置和位置。 接收机包括多个麦克风,用于捕获从探头发射的超声波波形,以产生捕获的超声波波形;以及数字信号处理器,对所捕获的超声波波形进行数字采样,并跟踪探针相对于接收机的相对位置和移动 三维超声波感应空间从飞行时间波形分析。 相对于髋关节置换手术示出实施例,但是可以考虑其他实施例。
