ABSTRACT:
A method of evaluating the status of bone tissue useful in the diagnosis of osteoporosis measuring a characteristic of ultrasound transmission through the calcaneus at a number of locations at an image forming degree of spatial resolution, deriving from said measurements information regarding the location of an approximately circular (as seen by measurements from the side) area of reduces attenuation in the calcaneus, optionally making further ultrasound measurements which reflect said bone tissue status, and evaluating said bone tissue status based on such said measurements and/or said further measurements at said location.
