AB  - Transducers  are  defined  as  devices  converting  one  form  of  energy  into  another.  In  the  case  of  ultrasound,  electrical  energy  is  converted  into  mechanical  (acoustic)  energy.  The  most  familiar  transducer  is  a  telephone  receiver,  with  an  earpiece  that  converts  electrical  impulses  into  sound  waves  and  a  mouthpiece  that  converts  sound  energy  into  electricity.  Imaging  transducers  combine  both  functions  by  emitting  and  receiving  ultrasound  pulses  and  converting  them  into  electrical  impulses  for  further  processing.  Nonimaging  continuous-wave  (CW)  Doppler  transducers,  just  like  the  telephone  receiver,  have  two  elements:  one  is  constantly  emitting  sound  and  the  other  is  receiving  sound.  Figure  3-1  shows  the  anatomy  of  the  imaging  transducer.
