<p>A system ( 60 ) and method ( 20 ) of creating an ultrasonic image ( 48 ) of a hard tissue ( 70 ) within a target ( 68 ). The method ( 20 ) includes comprising transmitting ( 22 ) from a defined location ( 64 ) a beam energy ( 66 ) towards the target ( 68 ), adjusting ( 24 ) the angle of incidence between the beam ( 66 ) the hard tissue ( 70 ) to a normal angle, receiving ( 26 ) an echo-reflection at said defined location ( 64 ), calculating ( 32 ) a set of position co-ordinates ( 46 ) the surface causing the echo-reflection repeating ( 36 ) the sequence from additional locations ( 64 ), compiling ( 38 ) position co-ordinates ( 46 ) to generate a map ( 48 ) of the surface ( 69 ) causing the echo-reflection ( 65 ), and determining ( 40 ) a map ( 48 ) which represents a surface ( 69 ) of the hard tissue ( 70 ) by a predetermined rule. An additional method ( 90 ) employing reception of the echo reflection ( 60 ) at additional defined locations ( 64 ) is disclosed, as are systems ( 60 ) for performance of the claimed methods ( 20 ) ( 90 ).</p> |
