Volumetric  imaging  based on the principle of electrical capacitance tomography (ECT),  called  electrical  capacitance  volume  tomography  (ECVT),  has  been developed  in  this  research  as  a  basis  for  imaging  in  medical  aplication.  The techniques used are based on capacitance measurements throughout the geometry of  three-dimensional  volumetric  objects  covered  with  capacitance  sensors.  This development enables real-time imagingof volume three object The development of the  imaging technique  includes of 3-D sensor design to obtain optimal  image reconstruction  technique  .Algorithm  development  in  recontruction  image  of ECVT.  This  research  has  been  done  by  simulation  and  computation  of reconstructed the electric field using COMSOL Multiphysics software based on the  fimited  element  method  and  using  MATLAB  2007b.  The  results  are  also compared  with  experimental.The  experimental  used  provides  phantom  with condition similiar to the real  fetus. The results of the reconstruction the basis of imaging the fetus in the uterus.
