The present disclosure relates to an ultrasonic diagnosis system. More particularly, the present disclosure relates to an apparatus and method for a real-time multi-view three-dimensional ultrasonic image user interface for an ultrasonic diagnosis system which can render three-dimensional volume data of an object obtained by three-dimensional ultrasonographic imaging into three-dimensional image data from each of a plurality of virtual viewpoints, and display the object from each of the viewpoints simultaneously on a real-time basis.
