Ultrasound Based Estimation Of Muscle Contraction
Abstract
In the absence of a single satisfactory control path horn the amputee to the prosthesis,
the search for new alternatives is of great interest. This paper introduces the idea
of using ultrasound measurements of human tissue as a basis for generation of control
inputs to a piosthesis. One of the methods employed, an optical flow estimation algotithm,
is based on the work of others, but a simpler, onedimensional implementation is developed.
The second method presented is based on cross correlation and is demonstrated to yield
smooth muscle force estimates under ideal conditions The results are compared to those
obtained with an EMG based technique. Weaknesses are discussed and suggestions for
further research are given.
