Electroacoustic Tissue Imaging

Abstract

The goal of this research has been to develop new methods of imaging tumors. The primary effort has been in developing an imaging method based on the ultrasonic vibration potential. We have formulated a complete theory of image formation for an arbitrary shape object irradiated by a plane wave. Experiments have been carried out that verify the theory and demonstrate straightforward examples of the use of the method. Work has focused on construction and optimization of an apparatus for scanning a transducer and recording images. Additionally, we have investigated the use of phase contrast x-ray imaging for tumor detection using ultrasonic radiation pressure to modify x-ray phase contrast images. Experiments have been carried out with phantoms to demonstrate the method.
