ABSTRACT:
An apparatus and methods for determining a measure equivalent to broadband sound attenuation from transient or other measures derived from acoustic signals propagated through bone and, additionally, for using this measure for the calibration of an ultrasound bone analysis instrument. A synthetic mathematical filter corresponding to a given value of broadband ultrasound attenuation is applied to the signal propagated through a calibration of known or neutral acoustic properties. The value of the acoustic measure corresponding to the resultant waveform is determined and associated with the broadband ultrasound attenuation value corresponding to the synthetic mathematical filter. A model relating the acoustic measure to BUA values may thereby be established for subsequent clinical application.
