Research has been directed towards developing new methods for imaging tumors. The primary effort has been in developing an imaging modality based on an electrokinetic effect known as the ultrasonic vibration potential. We have formulated a theory for current generation and image formation for an arbitrary object irradiated by a plane wave as well a theory for focused waves. Experiments have been carried out to verify the theory and demonstrate the method. Work has focused on plane geometries during this period. Additionally, we have investigated the use of phase contrast x-ray imaging for tumor detection. Experiments have been carried out with commercial tumor phantoms to evaluate the method. A method of calculating phase contrast images has been found.
