Abstract
An apparatus for ultrasonic elastography includes a housing, a moveable surface, and a transducer in ultrasonic communication with the moveable surface. A driver is arranged to mechanically move the moveable surface with respect to the housing. The housing can also be formed such that the moveable surface is a moveable exterior surface of the housing, such as a compliant membrane, which is moved in response to the driver to induce tissue compression. The housing may be arranged to be held in an operator's hand. Alternatively, the housing may be arranged for an insertion into an opening in a patient's body. The driver may move the transducer or moveable exterior surface in a cyclical manner at a low frequency.
