ABSTRACT:
An instrument for measuring the strength and integrity of bone in vivo by ultrasound pulse taking its data by measurement of the os calcis or heel bone. The measured data is processed so that the instrument is capable of presenting its output in units of estimated spinal bone density, a value of recognized clinical value and acceptance. It has been determined that, using both the changes in the speed of ultrasound in the patient's heel and the broadband ultrasonic attenuation of the ultrasonic pulse as it transmits through the patient, that a value for estimated spinal bone mineral density can be calculated which correlates very well with actual measured values of spine mineral density.
