AB Ultrasound  imaging  uses  the  pulse-echo  principle  in  which  a  short  burst  of  sound  waves  are  emitted  from  a  transducer  and  directed  to  the  underlying  tissue.  Diagnostic  ultrasound  uses  sound  waves  of  frequencies  between  2  and  20  MHz.  When  a  sound  beam  is  directed  toward  the  body,  tissue  reflects,  absorbs,  or  scatters  the  beam.  Each  of  these  responses  determines  the  nature  of  the  received  signal.  The  sum  of  acoustic  energy  losses  from  absorption,  scattering,  and  reflection  is  called  attenuation.
