| 摘 要： | 目的针对假肢接受腔设计过程中，常规CT获取扫描残肢断层数据成本高和电离辐射大等问题，设计用超声波测量方法获取残肢骨骼皮肤轮廓。方法首先开发超声波测量装置测量残肢，得到残肢超声图像，再设计复合算法对超声图像进行二维重建，完成残肢骨骼与皮肤的特征提取。结果和结论与同类断层扫描技术相比，超声波测量方法极大地降低了成本和减少了辐射，为假肢康复工程领域等图像的断层扫描提供了一种新的手段。

| Abstract: | ObjectiveIn the prosthetic socket design process, the high cost and radiation deficiency caused by CT scanning which is a routine way to obtain the cross section image of the residual limb remain problems. Ultrasonic measuring approach is proposed to gain the bones and skin contour of the residual limb. MethodsAn ultrasonic measuring device to get the multiple ultrasonic images of the residual limb was developed firstly, a compound algorithm to reconstruct the multiple images into 2D image was designed, and then the feature extraction on the bones and skin was made. ResultsConclusionComparing with the like-kind cross sectional scanning technique, the ultrasonic measuring method has the characteristic of no radiation and low cost. [ |
