Abstract: 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).

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.

Abstract: A method and a system for playing a first type of data, such as audio stream data, for the user while simultaneously displaying an advertisement in the form of a second type of data, such as video data. The system and method enable advertisements to be displayed while music is being played from an audio file by the computer of the user, thereby providing an alternative revenue source for the owner of the rights to the audio data. Furthermore, since the advertisement is in a data format, preferably video data, which is different from that of the audio music file, the display of such an advertisement does not interfere with the enjoyment of the music or other audio data being played.
