  • COMPACT ULTRASOUND TRANSDUCERS FOR INTRAORAL USES
    Publication number: 20250330754
    Abstract: The present disclosure describes an ultrasound sensor for soft-tissue imaging comprising: a piezoelectric element having a front side to be used for emitting ultrasound signals and for receiving echoed ultrasound signals to be measured and a back side; and a backing element having a front side shaped to match the shape of the piezoelectric element back side, the backing element being made of a structured composite material comprising at least two base material, one of the two base material being a metal, the at least two base material having significant different acoustic impedance so that the backing element has an acoustic attenuation greater than 1.2 dB/mm/Mhz.

  • Ultrasound probe and device for 3D imaging of the jaw
    Patent number: 11045166
    Abstract: This invention concerns an ultrasonic dental imaging probe (1), typically comprising several transducers (4) arranged to operate as a transmitter and a receiver, and in particular arranged to transmit ultrasonic waves at a frequency of at least 10 MHz, and optionally several transducers (4) arranged to operate as a transmitter and a receiver and arranged to transmit ultrasonic waves at a frequency of less than 4 MHz. The transducers are mounted on a flexible support (3), secured to a rigid frame (2) typically in a “U” shape. The invention also concerns a device comprising one such probe.
