ABSTRACT:
An apparatus for positioning and holding an individual in a prescription posture followed by a determination of the surface contour of the posterior trunk. The positioning utilizes an array of adjustable pads arranged in rows. The shape sensing is accomplished by tracing a transverse cross-section of the posterior half of the trunk, at serial increments along the vertical axis of the trunk. The tracing is based on angular orientation, linear displacement and vertical elevation of a sensor mounted on a radial arm.
