Automated three dimensional (3D) mapping and display system for a diagnostic ultrasound. Ultrasound probe position registration is automated, the position of each pixel in the ultrasound image in reference to selected anatomical references is calculated, and specified information is stored on command. The system, during real time ultrasound scanning, enables the ultrasound probe position and orientation to be continuously displayed over a body or body part diagram, thereby facilitating scanning and images interpretation of stored information. Ultrasound free hand two-dimensional (2D) frames in a video sequence (clip) or cine loop are recorded; wherein multiple 2D frames of video sequences corresponding to a scanned volume can be reconstructed in 3D volume images. In later examinations, the exact location and position of the transducer can be re-created along 3D or 2D axis points, enabling known targets to be viewed from a chosen position. |
