Method and apparatus using golay-coded excitation for echocardiology

摘要: For ultrasound imaging using Golay-coded excitation for echocardiology, at least three focused and coded beams are transmitted a fundamental frequency to each transmit focal zone during acquisition of acoustic data single image frame. The resulting receive vectors then undergo correlation “slow-time” filtering, i.e., filtering from firing firing. is accomplished by multiplying set filter coefficients respective scalar weightings before summing the filtered subsequent processing form one scan line. Employment more than two firings suppresses sidelobe response without altering mainlobe substantially in presence tissue motion after weighted have been summed.
