Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a transmitter/receiver switch circuit for an ultrasound system which is improved to semiconductor transistor design, reliability, and efficiency.SOLUTION: An ultrasound system includes an ultrasound transducer and a bi-directional transistor 104 coupled to the ultrasound transducer. The ultrasound system also includes an ultrasound receiver coupled to the bi-directional transistor. The bi-directional transistor operates to selectively connect the ultrasound transducer to ground and to selectively connect the ultrasound transducer to the ultrasound receiver.SELECTED DRAWING: Figure 2 【課題】半導体トランジスタ設計、信頼性、及び効率に対して改善された、超音波システムの送受切換回路を提供する。【解決手段】超音波システムが、超音波トランスデューサ、及び超音波トランスデューサに結合される双方向トランジスタ１０４を含む。超音波システムは、双方向トランジスタに結合される超音波レシーバを更に含む。双方向トランジスタは、超音波トランスデューサを接地に選択的に接続するように、及び超音波トランスデューサを超音波レシーバに選択的に接続するように動作する。【選択図】図２
