Abstract: A diagnostic process for generating, recognizing, and remotely examining layers of tooth using processed reflection data from physical waves to produce high-resolution quantitatively measurable 3D images. The present invention examines interior portions of tooth structure. The layers can be considered to be common impedance objects, which are present in a uniform background. Acquire data sets for the area of interest and then acquire a 3 dimensional reflection data volume. This data is then subjected to diagnostic 3 dimensional processing to produce a vertical and horizontal high-resolution matrix. In a similar manner this method of imaging tooth structure can be used to measure other hard structures in the body (i.e. bone) or outside the body (i.e. cement, concrete, rock etc).
