Title: (EN) TRANSMIT-RECEIVE SWITCHING APPARATUS FOR AN ULTRASOUND SYSTEM, CAPABLE OF IMPROVING THE QUALITY OF AN ULTRASOUND IMAGE
(KO) 스위칭 장치를 구비하는 초음파 시스템
Abstract: front page image
(EN) PURPOSE: A transmit-receive switching apparatus for an ultrasound system is provided to completely insulate a receiving part while an ultrasound signal is received by converting a diode bride into an off-state. CONSTITUTION: One end of a diode bridge is connected with a transmitting part(110), a receiving part(130), and an ultrasound probe(120). The other end of the diode bridge is connected with the receiving part. A switching part(140) is connected with the diode bridge. The switching part converts the diode bridge into an off-state while an ultrasound signal is transmitted in order to block a receiving signal to the receiving part. The switching part applies a bias current to the diode bride while the ultrasound signal is received in order to transmit the received signal to the receiving part. COPYRIGHT KIPO 2011
(KO) 초음파 신호의 송신동안 수신부를 완전히 절연시키는 스위칭 장치를 구비하는 초음파 시스템이 개시된다. 초음파 시스템은 복수의 송신신호를 형성하도록 동작하는 송신부; 복수의 송신신호를 복수의 초음파 신호로 변환하고 복수의 초음파 신호를 대상체에 송신하며, 대상체로부터 반사되는 복수의 에코신호를 수신하고, 복수의 에코신호에 기초하여 복수의 수신신호를 형성하도록 동작하는 초음파 프로브; 복수의 수신신호를 수신하도록 동작하는 수신부; 및 송신부, 상기 초음파 프로브 및 상기 수신부에 연결되는 스위칭부를 포함하고, 스위칭부는, 제1 및 제2 상태 간에 스위칭 가능한 복수의 다이오드 브릿지를 포함하고, 제1 상태의 경우, 복수의 송신신호 각각이 수신부에 전달되는 것을 차단하고, 제2 상태의 경우, 복수의 수신신호 각각이 상기 수신부에 전달되도록 한다.
