Although ultrasound imaging is a well accepted clinical, diagnostic             tool in medicine, there is still a lack of understanding concerning the         mechanisms of interaction.  This research effort will characterize              ultrasonic wave propagation by means of mathematical modeling and               experimental verification.  Both statistical and deterministic                  approaches will be employed to examine parameters such as wavefront             distortion and refraction errors to better characterize the ultrasonic          field in tissue.  The results of this investigation are expected to             help define limits of resolution for ultrasonic imaging systems.
