Design of a non-contacting electromagnetic device for measurement of the vibratory response of long bones

Development of noninvasive methods for quantitating the bone mass is important in the diagnosis and treatment of many skeletal diseases, particularly for osteoporosis. As standard roentgenographic methods can not detect early osteoporosis, presently quantitative computed tomography (QCT), and single, and dual photon absorptiometry are being used to monitor the skeletal health of elderly population, Although widely used clinically, these methods are relatively expensive and they involve some exposure to radiation.
