  • Publication number: 20250177786
    Abstract: The present invention relates to a therapeutic ultrasound generation device, and a handpiece for ultrasound treatment including same. The therapeutic ultrasound generation device comprises: a cartridge housing unit; an ultrasonic transducer unit that is located in the cartridge housing unit, is disposed inclined with respect to a rotational central axis direction, and generates ultrasonic waves in the inclined direction; an inclined block unit that is located in the cartridge housing unit, has an inclined surface on the lower surface thereof, and supports the upper surface of the ultrasonic transducer unit such that the ultrasonic transducer unit is inclined with respect to the rotational central axis direction; and a rotating motor that rotates the inclined block unit. The therapeutic ultrasound generation device simplifies the structure of moving the focal point of the ultrasonic waves, generated by the ultrasonic transducer unit, in a circular shape on the same plane.

  • Patent number: 10854010
    Abstract: Provided is a method, performed by a device, of processing an image, the method including tracking a movement of a user wearing the device and generating movement information of the user, the movement information being about a movement occurring between a previous time when a first image was rendered and a current time when a second image is rendered; selecting at least one pixel from among a plurality of pixels comprised in the first image, based on the generated movement information and a location of a target pixel comprised in the second image; and changing a value of the target pixel by blending a value of the selected at least one pixel with the value of the target pixel according to a preset weight.
