摘要:
An ultrasound transducer includes multiple ultrasound transducing elements formed as an ultrasound transducing array, to receive and transmit an ultrasound wave. A pulse controller outputs multiple pulse signals to respectively control the ultrasound transducing elements, wherein a flat wave front of the ultrasound wave propagates at different direction by control the time delay of the pulse signals. The pulse controller can just activates a portion of the ultrasound transducing elements for transmitting and receiving corresponding to a region of interest(ROI).一種超音波能量轉換裝置,包括由多個超音波能量轉換單元組成的一超音波能量轉換陣列,用以接收與傳送一超音波。一脈衝控制器輸出多個脈衝訊號分別控制該些超音波能量轉換單元,其中藉由該些脈衝訊號的輸出延遲,使所傳送的該超音波的平面波前,依照控制以有不同的行進方向。脈衝控制器可以對應一目標區域,僅啟動該些超音波能量轉換單元的一對應部分做傳送與接收。150...接收模組151...前級影像處理器152...後級影像處理器108...超音波能量轉換陣列200...反射波204...通道資料單元206...前級處理單元208...類比到數位轉換單元210、216...內插單元212、214...二維快速傅利葉轉換單元218...相位修正單元220...反快速傅利葉轉換單元222...解調單元224...子影像重合單元226...目標區域關聯處理單元
