AB Optimization  of  the  ultrasound  (US)  image  is  important  to  improve  the  visualization  of  the  relevant  anatomy  during  US-guided  peripheral  nerve  blocks  (PNBs).  Because  a  nerve  block  is  an  injection  of  local  anesthetic  (LA)  into  a  tissue  space  that  contains  the  nerve,  it  is  often  more  practical  and  easier  to  identify  the  interfascial  tissue  space  containing  the  nerve  than  the  nerve(s)  to  be  blocked.  Optimizing  the  US  image  requires  knowledge  of  how  the  US  machine  operates  and  adequate  training  in  image  acquisition.  In  this  chapter,  we  describe  standardized  scanning  steps,  including  the  selection  of  sonographic  modes,  adjustment  of  function  keys,  essential  transducer  maneuvers,  and  interpretation  of  artifacts  to  optimize  the  US  view  and  guide  the  needle  toward  the  target.
