Outline of Final Research Achievements

For the purpose of improving spatial resolution without compromising time resolution in ultrafast ultrasound imaging, we studied a coded pulse excitation method for demultiplexing signals. We developed a novel decoding method which can demultiplex simultaneous excited signals by solving an optimization problem. The proposed method was confirmed by numerical simulations and experiments.
