Abstract
The invention relates to a method for characterising bone, the method comprising the steps of receiving () ultrasonic wave echo signals transmitted into a body, determining () a speed of sound in the body's non-bone biological tissue, locating () a first demarcation curve between non-bone biological tissue and bone in an image of the body constructed during said determining step, and determining () a speed of sound in bone. The steps of determining speed include constructing images from the signals, and a metric calculation indicative of a focus quality in the constructed images.
