Zusammenfassung: | An ultrasonic device is disclosed. The ultrasonic device may comprise: a transducer for transmitting a plane wave; and a processor for controlling the transducer to sequentially transmit plane waves in a plurality of different traveling directions and thereby extend a transmission range in which the plane waves travel, wherein the transducer receives a plurality of ultrasonic signals which are reflected from an object by each of the transmitted plane waves, and the processor synthesizes the plurality of received ultrasonic signals so as to image at least a predetermined partial region in the extended transmission range. Therefore, the present invention can provide a wider image to a user of the ultrasonic device.
L'invention concerne un dispositif ultrasonore. Le dispositif ultrasonore peut comprendre : un transducteur servant à émettre une onde plane; et un processeur servant à commander le transducteur pour qu'il émette séquentiellement des ondes planes dans une pluralité de directions de propagation différentes et, de ce fait, élargisse une portée d'émission selon laquelle se propagent les ondes planes, le transducteur recevant une pluralité de signaux ultrasonores qui sont réfléchis depuis un objet par chacune des ondes planes émises, et le processeur synthétisant la pluralité de signaux ultrasonores reçus de façon à mettre en image au moins une région partielle prédéfinie de la portée d'émission élargie. Par conséquent, la présente invention permet de fournir une image plus large à un utilisateur du dispositif ultrasonore.
초음파 장치가 개시된다. 본 초음파 장치는 평면 파를 송신하기 위한 트랜스듀서 및 평면 파를 복수의 서로 다른 진행 방향으로 순차적으로 송신하여 평면 파가 진행되는 송신 범위를 확장시키도록 트랜스듀서를 제어하는 프로세서를 포함하며, 트랜스듀서는 송신된 각 평면 파에 의해 대상체로부터 반사되는 복수의 초음파 신호를 수신하고, 프로세서는 수신된 복수의 초음파 신호를 합성하여, 확장된 송신 범위 중에서 기설정된 적어도 일부 영역을 영상화할 수 있다. 이에 따라, 초음파 장치를 이용하는 사용자에게 좀더 넓은 영상을 제공할 수 있다. |
