I always liked that detective with the silver shinbone 我喜歡那個腿上是銀脛骨的偵探。
By comparing with the velocity in normal person ' s shinbone , osteoporosis can be diagnosed conveniently 與定量超聲波在正常脛骨中的傳播速度相比較,可以為骨質(zhì)疏松癥提供便捷的診斷手段。
The propagation velocity of ultrasound in patient ' s shinbone can be achieved by figuring out the time span between emergent wave and echo wave 根據(jù)相關(guān)公式,只需計算出超聲波發(fā)射信號和回波信號的時間差,即可獲得定量超聲波在受試者脛骨的皮質(zhì)骨中傳播速度。
