Electroacoustic Tissue Imaging
Abstract
Research has been directed towards detection of tumors using a new imaging modality based on an electrokinetic effect known as the ultrasonic vibration potential. Major accomplishments include completion of a theory for image formation for a colloidal object, such as a pool of blood, development of instrumentation for recording images, and testing of the theory with phantoms with differing geometries. Additionally, phase contrast x-ray imaging for tumor detection has been initiated. A high resolution imaging apparatus has been assembled and tested for imaging soft tissue. Methods for calculating phase contrast images from symmetrical bodies has been developed. The phase contrast method has shown unprecedented detail for imaging microvasculature.
