AB  - Motion  during  image  acquisition  can  cause  imagedegradation in all medical imaging modalities. This is particularlyrelevant  in  2-D  ultrasound  imaging,  since  out-of-plane  motioncan only be compensated for movements smaller than elevationalbeamwidth of the transducer. Localization based super-resolutionimaging creates even a more challenging motion correction taskdue to the requirement of a high number of acquisitions to forma  single  super-resolved  frame.In  this  study,  an  extension  of  two-stage  motion  correctionmethod is proposed for 3-D motion correction. Motion estimationwas  performed  on  high  volumetric  rate  ultrasound  acquisitionswith  a  handheld  probe.  The  capability  of  the  proposed  methodwas  demonstrated  with  a  3-D  microvascular  flow  simulation  tocompensate for handheld probe motion. Results showed that two-stage motion correction method reduced the average localizationerror  from  136  to  18μm.
