New laser-based photoacoustic ultrasound diagnostic method for osteoporosis |

EurekAlert: The new technique being developed for the purposes of assessing osteoporosis deploys, for the first time in the case of bone, laser-based photo-acoustic methods for producing ultrasound. "We direct a suitable laser beam at the surface of the skin to produce an ultrasound pulse that will propagate along the bone. This prevents contact problems during the measurement process. Furthermore, the ultrasound pulse can be easily tailored by adjusting the laser beam. This enables us to achieve a much more accurate measurement," Timonen describes.
