Claim 14:
15. A method for inspecting an object using an ultrasound inspection device and a coordinate positioning apparatus comprising a rotary head having at least two rotary axes, the ultrasound inspection device being attached to the rotary head and comprising an ultrasound transducer and a coupling element, the coupling element comprising a self-lubricating material for contacting and acoustically coupling to the object to be inspected, the method comprising:
a scanning step of moving the coupling element of the ultrasound inspection device along a path on a surface of the object while acquiring ultrasound measurements of the object; and
a step of determining a deformation of the coupling element during the scanning step to provide a measure of a height of the ultrasound inspection device above the surface of the object.
