ABSTRACT:
A system and method of mapping irregularities of hard tissue. The method includes repeatedly transmitting ultra-sonic energy towards the hard tissue at a first angle of incidence, registering the origin of transmission if an echo-reflection the hard tissue is received, defining the origin of transmission in six degrees of freedom, calculating position co-ordinates for a point causing the echo-reflection and changing the origin of transmission. The method further includes compiling position co-ordinates to generate a map of the irregularities in the surface of the hard tissue. The system includes at least one ultrasonic transducer, a central processing unit and a position locator and adjustment mechanism operably connectable and configured to accomplish the disclosed method.
