Abstract
Abstract The body member positioning apparatus disclosed herein operates to clamp a body member, such as a foot, in relation to a fixture, e.g. such as may be used for ultrasonic bone testing. A shell member is provided which conforms to the expected shape of the body member with a space therebetween, this space being filled with a compliant foam liner. An inflatable bladder or bellows operates between a stationary housing part and a movable housing part to which the shell member is attached so that, by inflating the bladder, a clamping pressure can be exerted against a body member positioned between the shell and the fixture.
