Abstract:
Objective In 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. Results Conclusion Comparing with the like-kind cross sectional scanning technique, the ultrasonic measuring method has the characteristic of no radiation and low cost.
