  • Ultrasonic generator
    Patent number: 11576653
    Abstract: An ultrasonic generator includes an ultrasonic wave source and a converging portion. The converging portion includes a first reflecting portion which reflects the ultrasonic wave generated by the ultrasonic wave source on its first reflecting surface, a second reflecting portion which reflects the ultrasonic wave reflected by the first reflecting surface on its second reflecting surface, and a waveguide serving as a transmission path for the ultrasonic wave. The waveguide is disposed such that the ultrasonic wave reflected by the second reflecting surface is introduced through an introduction portion thereof. The focal point of the second reflecting surface and the focal point of the first reflecting surface are disposed such that the ultrasonic wave reflected by the second reflecting surface becomes a plane wave.
    Type: Grant

  • Ultrasound probe, ultrasonograph, and ultrasonography
    Patent number: 8021305
    Abstract: A non-invasive (having sufficiently small diameter so as not to give much pain to a subject) ultrasonic ultrasound probe of high spatial resolution and high signal-to-noise ratio, an ultrasonograph using the probe, and an ultrasonography are provided. The ultrasound probe is inserted into the tissue under examination and transmits an ultrasonic wave.
