An ultrasound reflection technique was designed and implemented to study the mechanical properties of bone material. The technique uses the fact that an ultrasound beam produced in water undergoes total internal reflection off a bone sample at a critical angle formally related to the velocity of a pressure wave in bone. When the plane of scattering is rotated around the normal to the sample surface, the critical angle varies with a periodic dependence dictated by the intrinsic symmetry of the…

It may be expected that the ultrasound parameters will prove to be useful predictors of bone strength and of its dependence on orientation, as well as having the potential for providing useful information on problems of current biomedical interest.

This study confirms that the organic matrix exerts a profound influence on the elasticity and indicates that the measurement of elastic properties at multiple directions is necessary in the assessment of bone mechanical competence.
Assessment by reflection ultrasound method of the effect of intermittent slow‐release sodium fluoride‐calcium citrate therapy on material strength of bone
The results support the possibility that intermittent slow‐release sodium fluoride treatment in combination with calcium citrate can enhance the strength of whole bone (spine) by improving the microscopic or material property of bone, as well as by increasing bone mass.
Accuracy of elastic property measurement in mandibular cortical bone is improved by using cylindrical specimens.
Testing whether ultrasonic velocities could be reliably measured in cylindrical samples of aluminum and mandibular bone, and the effects of reduced specimen thickness found that varying shape had minimal effects on ultrasonic Velocities or derived elastic properties.


The measurement of broadband ultrasonic attenuation in cancellous bone.
The frequency dependence of ultrasonic attenuation in the range 0.2–1 MHz in in vitro samples of bovine cancellous bone and in vivo os calcis heel bones indicates that the technique allows determination of bone loss and the study of the onset and progress of osteoporosis.
Measurement of the velocity of ultrasound in human cortical bone and its potential clinical importance. An in vivo preliminary study.
The velocity of ultrasound in human cortical bone has been measured in vivo by a pulse echo technique and it is suggested that this change results from a proportionately greater decrease in the elastic constant of the bone, compared with its density.

Anisotropy in hard dental tissues.
Measurement of the velocity of ultrasound in human cortical bone in vivo. Estimation of its potential value in the diagnosis of osteoporosis and metabolic bone disease.
The authors feel that a combination of U and BMC permits better discrimination between normal and abnormal in patients with osteoporosis or metabolic bone disease than either parameter alone.
Ultrasound as a tool for assessment of bone quality in the horse
A simple non-invasive method is described for calculating the transverse apparent velocity of sound of horse bone using the metacarpal bone and its covering soft tissue and a good correlation was obtained between Velocity of sound measurements and bone mass.
