AB DefinitionsThree-dimensional  ultrasonography  (3DUS  or  volume  sonography):  an  imaging  method  that  fundamentally  converts  digital  2D  picture  elements  (pixels)  into  3D  voxels.Four-dimensional  ultrasonography:  an  imaging  method  that  adds  the  dimension  of  time  to  volume  data  sets  acquired  using  3DUS  that  is  especially  useful  for  the  fetal  heart  and  moving  limbs.Multiplanar  display:  the  instantaneous  and  interactive  display  of  3  perpendicular  views  (ie,  sagittal,  transverse,  and  coronal  views).Voxel:  short  for  volume  pixel.  It  is  the  smallest  unit  of  a  three-dimensional  volume  equivalent  of  a  pixel  in  a  2D  image.Rendering:  the  process  of  displaying  groups  of  voxels  with  post-processing  software  to  display  either  surface  features  (surface  rendering)  or  internal  anatomic  structures  (volume  rendering).Reformatting:  the  process  of  volume  exploration  where  particular  image  planes  are  obtained  either  in  a  multiplanar  or  rendered  display.STIC  (spatio-temporal  image  correlation):  a  volume  analysis  technique  that  is  designed  to  acquire  and  display  moving  volumes  of  the  fetal  heart.Matrix  2D  array:  a  transducer  with  a  large  number  of  piezoelectric  elements  that  allow  electronic  steering  and  rapid  real-time  acquisition  of  moving  objects  such  as  the  fetal  heart.Volume  contrast  imaging:  a  3D  image  projection  that  is  variably  defined  by  several  layers  of  voxels  (i.e.  "thick  slice")  rather  than  from  a  thin  layer  of  pixels  used  for  2D  ultrasonography.
