Electroacoustic Tissue Imaging
Abstract
The primary objective of this research has been to develop a new method of imaging based on the ultrasonic vibration potential. The method has not been explored before for imaging. Research has focused on building radiofrequency amplifiers in the 0.5 to 10 MHz range that have the highest signal-to-noise ratios possible since extraction of the signal is the most critical part of the imaging system. Theoretical work has been done on modeling the signal generation which is unique to the vibration potential. Experiments have been carried out on colloidal suspensions to confirm some of the predictions of the theory. Experiments with phase contrast x-ray imaging have been carried out showing the highlighting of regions having large density gradients.
