Disclosed is an apparatus and method for producing a three-dimensional
(3D) moving image of a moving target object. The method comprises the steps of
transmitting and receiving ultrasound signals to/from the moving target object;
obtaining raw data; generating image frame data based on the obtained raw data;
generating virtual image frame data based on the generated image frame data; and
rendering a 3D moving image of the moving target object using the image and virtual
image frame data. The apparatus comprises a probe, a raw 3D data obtaining unit,
and an enhanced live 3D imaging unit for producing a 3D image of the moving target object.
