Electroacoustic Tissue Imaging
Abstract
The goal of this research has been to develop new methods of imaging for diagnosing breast cancer. The primary focus of the research, to date, as been on exploring the ultrasonic vibration potential as an imaging method. Research during this period has been on designing and building apparatus, optimizing radio frequency amplification and signal processing schemes, and writing computer programs to store and manipulate data to form images. Theoretical work has been carried out giving a general expression for the vibration potential signal for an object with an arbitrary shape. Experiments have been done on colloidal suspensions to confirm some of the predictions of the theory and to create a several images. Additionally, experiments with phase contrast x-ray imaging have been initiated using a micro focus x-ray tube.
