This invention provides a system and method for the automatic alignment and co-orientation of a 3D anatomical model adjacent to one or more 2D MPR views of a 3D echocardiographic image dataset. The 3D model is presented in alignment with the displayed 3D and 2D images to provide an indication of the orientation of each of the 3D volumetric and 2D planar views relative to the 3D model and relative to each other.
