Abstract
The ultrasonic vibraton potential refers to the production of a time varying
voltage when ultrasound passes through a colloidal or ionic solution. The
vibration potential can be used as an imaging method for soft tissue by
recording its phase, time of arrival, and magnitude relative to the
launching of a burst of ultrasound. A theory of the effect can be found
from Maxwell's equations. Experimental results demonstrating the imaging
method are shown for bodies with simple geometries.
