Abstract

Stress and strain are determined at boundaries within a medium, for 3D imaging of a residual limb and for the design of prostheses and orthoses. A probe comprising load cell (102) is mounted behind an ultrasound transducer (104). A computer (108) determines and displays the position (112) of a boundary in the medium using conventional ultrasonic scanning techniques. The computer (108) determines the strain (114) at the boundary using two or more measured positions of the boundary. The computer (108) determines the stress (116) at the boundary using the load and position of the boundary and also using a model (118) of the propagation through the medium of the pressure wave imparted by, the probe. For scanning a residual limb, the probe is mounted in a scanner (302) and rotated around the limb and dragged across its surface, or mounted in a glove (402) or sock (502).
