Title:
METHOD AND APPARATUS FOR ULTRASONIC DIAGNOSIS
Document Type and Number:
Japanese Patent JPS57122855
Kind Code:
A
Abstract:
An ultrasonic probe for propagating an ultrasonic surface wave which is constrained along the probe with the evanescent pressure field penetrating the subject in a direction orthogonal to the axis of the probe. The ultrasonic probe may then be placed about a plurality of orientations, passing the evanescent pressure field through the subject along the plurality of orientations and detecting the loss of energy in each successive pressure field propagation. A data processing system for processing and correlating each successive detected energy loss in each propagation direction can produce a resultant computed tomographic image of a defined plane through the subject.
