Abstract
A method and system for indicating the position and orientation of a scan plane relative to a patient is provided. The image as presented on a display is oriented in accordance with the orientation of a transducer. The orientation may provide for displaying an image where the transducer is not in a transducer up or transducer down position, but is rotated away from vertical of the display. Alternatively or additionally, a two or three-dimensional graphical generic representation is provided with a scan plane indicated as a polygon or image rendering within a generic representation to show relative positioning of the scan plane with respect to the patient.
