  • Publication number: 20170035391
    Abstract: A display device for ultrasound energy includes a focused ultrasound emitting and receiving device, a processing device and a display. The processing device generates a first electrical signal and transmits it to the focused ultrasound emitting and receiving device to control the focused ultrasound emitting and receiving device to emit at least one first ultrasound signal to a target position of an organism. The target position reflects the first ultrasound signal to form at least one second ultrasound signal. After generating the first electrical signal, the processing device drives the focused ultrasound emitting and receiving device to start to receive the second ultrasound signal only during a preset period after the estimation period. The processing device uses the display to display an image of the target position according to the second ultrasound signal, and brightness of the image is directly proportional to energy intensity of the first ultrasound signal.

  • Publication number: 20150182195
    Abstract: A processing system and a confocal processing method for confocally emitting and receiving ultrasound. Firstly, a first driving electrical signal is generated. Then, at least one first ultrasound signal having a main frequency is emitted to a reflection position according to the first driving electrical signal. With an object at the reflection position, the first ultrasound signal is reflected to form at least one second ultrasound signal. Then, a first analyzed signal whose frequency lower than the main frequency is retrieved from the second ultrasound signal, and other signals are eliminated from the second ultrasound signal, and the first analyzed signal is converted into at least one first analogous signal. Finally, first energy of a first fixed bandwidth of the first analyzed signal is retrieved by the first analogous signal. The method stops generating the first driving electrical signal when the first energy is larger than a predetermined value.
