  •   本研究主要利用震波聚焦於骨骼與組織間進行觀察與測量其作用之結果,利用這些實驗結果來瞭解實際震波在骨骼與組織之間作用的情形,在本研究中發現,在骨疾治療時會由於第二焦點的定位方式不同而影響震波聚焦,也因此對骨骼與組織間受力分佈產生影響。在模擬鈣沉積物受震波作用時,其結果顯示以能量約為 之震波來治療會比由能量比較低的震波治療的效果來的好。而當震波在骨骼與組織之作用會由於彼此間界面的不同聲學性質而產生不同行為的反射震波因此使得震波在組織內的產生受力作用大小的範圍產生不同的變化。當震波焦點為骨骼正下方,且震波產生器中心軸線垂直骨骼中心線時,其作用力比較大的區域會在骨骼正下方的組織中,但是當震波聚焦點在骨骼側面,而震波產生器之中心線與骨骼表面相切時,其作用力最大的區域則在骨骼側面震波聚焦點的側面下方。在本研究中亦開發了一部擬測量組織中受力情形的儀器,此光纖式水聲儀的設計開發,目前已完成儀器組裝以及初步的訊號的測試,也確認了其光訊號會因為壓力使液體密度改變而產生調變,詳細的校驗仍待更進一步的測試來完成。

      The experimental investigation on how the condition of shock focusing on the osseous tissue and soft tissues adjacent to bones, will affect the tissues and bones has been done. The results show that the variation on the positioning of the shock wave focus with respect to the bone will effect the pressure distribution on the near by tissue. With a moderate shock wave energy~ to act on the simulate calcific deposit will offer a better results than shock with lower shock wave energy. With the study of acting of shock waves on the osseous tissue and soft tissues adjacent to a bone, it has been observed that with focus underneath the bone surface and axis of shock generator perpendicular to bone axis, the maximum pressure distribution inside the tissue is observed underneath the bone area. However, with the focus beside the bone surface and axis of shock generator tangent to the bone surface, the maximum pressure distribution inside the tissue has been observed underneath the focusing side of the bone surface. This investigation also developed a fiber optic probe hydrophone. The instrument has been designed and being assembling completely. The initial testing has been done. The results show that the output signal can modulated with pressure which changes the water density. However, the detailed calibration need to be done in the near future.
