title: High frame rate ultrasound coded excitation.
abstract: an ultrasound imaging method which can achieve high frame rate and good SNR without sacrificing the resolution is proposed. Compared with other reported high frame rate imaging methods, the proposed imaging method can achieve 12dB SNR improvement while keeping the high frame rate. The methods are based on the application of the synthetic transmit aperture (STA) beamforming, coded excitation, defocusing delay and MisMatched Filter (MMF) technique. Field II has been applied to simulate the phantom result to verify the method.
