Outline of Final Research Achievements

In this study, we aim to perform high-definition imaging, high-functional imaging and high-resolution imaging. We proposed some new methods for speckle suppression and FDA compensation of harmonic imaging as high-definition imaging, elastography specially used for tumor in consideration of living body safety as high-functional imaging and super resolution synthetic aperture method based on the phase information of carrier waves. The effectiveness of these methods was confirmed through FEM simulations and experiments.
