Apparatus and method for detecting cavitations using through-transmision alveolar ultrasonography (tau)

An apparatus comprising a measuring unit for performing through-transmission alveolar ultrasonography (TAU) for locating cavitations in a jawbone, wherein the measuring unit comprises an ultrasonic transducer and a round ultrasonic receiver, the apparatus being configured to define the geometric position of the ultrasonic transducer and the ultrasonic receiver with respect to each other, wherein the ultrasonic transducer is coupled to an arm and the ultrasonic receiver of the measuring unit is coupled to another arm, wherein the arms are connected to each other by a connecting element, and wherein at least one of the arms is pivotably coupled with the connecting element.

A method for calibrating and testing the proper functioning of an apparatus comprising a measuring unit for performing through-transmission alveolar ultrasonography (TAU) for locating cavitations in a jawbone, wherein the measuring unit comprises an ultrasonic transducer and a round ultrasonic receiver, the apparatus being configured to define the geometric position of the ultrasonic transducer and the ultrasonic receiver with respect to each other, wherein the ultrasonic transducer is coupled to an arm and the ultrasonic receiver of the measuring unit is coupled to another arm, wherein the arms are connected to each other by a connecting element, and wherein at least one of the arms is pivotably coupled with the connecting element, the method comprising performing a plurality of ultrasonic measurements successively in media with different and known acoustical properties and comparing the results of the performed ultrasonic measurements with default values.
