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.

Determination of acoustic velocity in bone

A method of determining an acoustic velocity in a bone, comprising:

Bone velocity determination

A method of determining the velocity of a flowing material, suspended in a liquid and flowing in a conduit, including irradiating the conduit with ultrasonic waves, detecting first Doppler-shifted reflections of the waves from the material, which first reflections have a positive Doppler-shift, and detecting second Doppler shifted reflections of the waves from the material, which second reflections have a negative Doppler-shift. The flow velocity is estimated based on the extent of the positive and negative Doppler-shifts. The first and second reflections may be summed to form a composite signal and the range of Doppler-shifts in the composite signal is used to estimate the flow velocity.

Method and device for a blood velocity determination

A method for determining, through an interposing medium, the mechanical properties of a solid having a surface, including transmitting a first ultrasonic wave along a transmission path from a first location through the interposing medium, along the surface and from the surface through the interposing medium to a second location; measuring the travel time of the first wave along the transmission path; measuring the thickness of the interposing medium; measuring the acoustic velocity of the interposing medium; and calculating the acoustic velocity in the solid based on the distance between the locations, the thickness of the interposing medium and the acoustic velocity in the interposing medium.
