Abstract
A method for determining an acoustic velocity in a segment of a bone covered with a layer of soft tissue having an outer surface, which includes determining a first travel time of a first ultrasonic wave along a first path from the outer surface back to the outer surface which path includes at least a first part of the bone segment together with determining a second travel time of a second ultrasonic wave along a second path from the outer surface back to the outer surface, which path includes at least a second part of the bone segment and also determining a third travel time of a third ultrasonic wave along a third path from the outer surface back to the outer surface which path includes at least a third part of the bone segment, and deriving the acoustic velocity in the segment of bone from the three determined travel times.
