Abstract: An automated 3D mapping and display system includes automated ultrasound probe position registration, calculation of the position of each pixel in the ultrasound image in reference to selected anatomical references, and storage of specified information on command. The system, during real time ultrasound scanning, enables ultrasound probe position and orientation to be continuously displayed over a body part diagram, thereby facilitating scanning and images interpretation of stored information. The system can record single or multiple ultrasound free hand frames in a video sequence or cine loop wherein multiple 2D frames of one or more video sequences corresponding to a scanned volume can be reconstructed in 3D volume images corresponding to the scanned region, using known 3D reconstruction algorithms. In later examinations, the exact location and position of the transducer can be recreated along 3D or 2D axis points enabling known targets to be viewed from an exact, known position.
