Abstract
A system for both measuring the sound velocity of tissue in an object and simultaneously providing a real-time B-mode image of the object. The system alternately image scans the object and cross scans the object so that a B-mode image of the object can be displayed while the object is being cross scanned by intersecting beams. By measuring the propagation times and displaying both a B-mode image of the object along with an image representing the cross scan signals, the user can view and correct errors caused by the reflection of echos waves from undesired reflection points, such as blood vessels.
