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.

- partially processing the digital signal data;
- storing the partially processed signal data in a memory;
- and
- transmitting the partially processed digital signal data to a software application being run by the processing means for final processing and subsequent transmission to a display unit associated with the system, further comprising the steps of:
- receiving the analogue signal data of groups of piezoelectric elements in sequence;
- and
- multiplexing and amplifying the analogue signal data generated by the ultrasonic receiver, further comprising a step of displaying further processed data by associating different signal strengths with at least one of:
- a grayscale comprising different tones, one or more color schemes comprising different colors and a graph, wherein signal data for unproblematic zones are displayed with reduced colored areas whilst data indicating peculiarities are displayed as large areas, further comprising displaying the further processed data by superimposing the further processed data over an x-ray image of a jawbone area being measured.
