Outline of Final Research Achievements

This study's objective is to improve medical ultrasound images. A method which uses split-and-merge strategy pulse compression technique and tissue harmonic imaging method was proposed. The method can overcome limitations of time and frequency domains. I investigated the feasibility of the method using the linear array transducer. Furthermore, the obtained results suggest that it can improve image quality by considering the phase difference between the harmonic and the fundamental components.
