An ultrasound system which is capable of biplane imaging is able to display, store and export independent image frames of only the reference image or only the variable orientation image, or the standard display of both images. The system is also able to sweep through a range of image plane orientations and automatically acquire an image in each orientation over the range of plane orientations. The system is preferably operable in the biplane tilt mode, the biplane rotate mode, or the biplane elevation tilt mode.
