Abstract
An ultrasound densitometer is disclosed in which ultrasonic transducers are located spaced apart in a water bath into which the heel of a person may be inserted. Attenuation and time of flight of an ultrasonic pulse are determined and combined to reduce the effect of heel width on the measurement without physically measuring the heel width. Bladders with selected coupling gels may be used to adjust the region at which the heel width effects are most reduced. A C-brace used to hold the transducers independent of the water bath permits their removal for servicing without upsetting their alignment and separation when reinstalled.
