Abstract
A system is disclosed for performing vibrational Doppler ultrasonic imaging. A vibrational wave of a first frequency is introduced into an area of a subject to be scanned. An ultrasound signal is simultaneously introduced into the area. The vibrational wave is of a sufficient frequency and amplitude to induce palpable vibrations in the tissue medium of the area being scanned. An ultrasonic Doppler imaging system detects these tissue vibrations and processes the resulting scanned data for display on a display device.
