  • Probe, ultrasound imaging apparatus and controlling method of the ultrasound imaging apparatus
    Patent number: 10595828
    Abstract: Disclosed herein is an ultrasound imaging apparatus and a controlling method thereof. The ultrasound imaging apparatus includes a controller configured to generate a control signal to control an operation of a probe, and a transceiver configured to transmit the control signal to the probe and to receive a signal transmitted from the probe. The controller may control the operation of the probe so that the probe may irradiate focused ultrasound energy when contrast agents composed of a silica nanostructure are injected into an object, and the controller may control the operation of the probe so that the probe may irradiate diagnostic ultrasound energy when the focused ultrasound energy is irradiated.
