AB Ultrasound  application  allows  for  noninvasive  visualization  of  tissue  structures.  Real-time  ultrasound  images  are  integrated  images  resulting  from  reflection  of  organ  surfaces  and  scattering  within  heterogeneous  tissues.  Ultrasound  scanning  is  an  interactive  procedure  involving  the  operator,  patient,  and  ultrasound  instruments.  Although  the  physics  behind  ultrasound  generation,  propagation,  detection,  and  transformation  into  practical  information  is  rather  complex,  its  clinical  application  is  much  simpler.  Because  ultrasound  imaging  has  improved  tremendously  over  last  decade,  it  can  provide  anesthesiologists  opportunity  to  directly  visualize  target  nerve  and  relevant  anatomical  structures.  Ultrasound-guided  nerve  block  is  a  critical  growth  area  for  new  applications  of  ultrasound  technology  and  become  an  essential  part  of  regional  anesthesia.  Understanding  the  basic  ultrasound  physics  presented  in  this  chapter  will  be  helpful  for  anesthesiologists  to  appropriately  select  the  transducer,  to  set  the  ultrasound  system,  and  then  to  obtain  a  pleasing  imaging.
