This paper describes a device that allows the imaging of prosthetic legs un
der load conditions using spiral computerized tomography (CT). The device c
onsists of a chair and a vertical footplate mounted on a 17.8X1.9 cm oak bo
ard that is 197 cm long. The load device can be easily positioned onto the
CT bed. A subject sits in the chair and applies force by pushing the foot p
ortion of the prosthesis against the footplate. The magnitude of the force
is monitored by a digital force gauge coupled to the footplate. Because the
load is borne by the hips and lower back of the subject against the chair,
substantial forces can be generated and steadily maintained for the 20-45
s duration of the CT study. This device has been used successfully with 19
transtibial amputees, allowing the acquisition of spiral CT studies with ha
lf and full body weight loads.
