| Research Abstract |
Checking the fit between a prosthetic socket and residual lib is important for functional prostheses. Designing a prosthetic socket using a CAD system and checking the above mentioned fit by analyzing the deformation and stress under the weight of an amputee requires a three-dimensional model of the residual lib that includes not only the surface, but also the fat, muscle and bone. An ultrasonic measurement system, including a probe the three-dimensionally measures the external surface shape and the shapes of internal tissues simultaneously was developed. The system uses wavelet analysis to define the positions of the boundaries between each tissue.
The lower limb model which made from model-bone and silicone rubber was measured using the system, which was shown to be capable of measuring radius with an error of 1.5mm. It is well known that there is a qualitative relationship between the loads exerted on a below-knee prosthesis and the stress exerted on the amputee's stump. The appropriate design system and developed to determine the highly measurement technique and Free Form Deformation method with Visible Human Model for FEM analysis holds promise for highly endurability of below-knee prosthesis
