Abstract: The present invention relates to an apparatus, method and system for detecting and locating dental cavitations in jawbones using Through-Transmission Alveolar Ultrasonography (TAU). The apparatus comprises a measuring unit comprising an ultrasonic transducer and a round ultrasonic receiver. The apparatus is a handhold and is configured to define the geometric position of the ultrasonic transducer and the ultrasonic receiver with respect to each other so as to achieve a high-resolution ultrasound image of the jawbone with minimal errors and in order to improve diagnosis of dental cavitations.

Abstract: A fiber optic cable having an outer jacket, a central coaxial member and at least one buffer tube wound around the central coaxial member, the buffer tube holding at least one optical fiber, where the buffer tube is shaped to allow extensive movement of the fiber radial to the cable axis, but allows only slight movement of the fiber in other directions. The buffer tubes may be filled with a gel to cushion optical fibers within.
