Golay Code in Third Transmit Phasing for Harmonic Contrast Detection

碩士 === 國立臺灣科技大學 === 電機工程系 === 98 === Ultrasonic harmonic image is limited by low signal-to-noise ratio (SNR) and insufficient contrast-to-tissue ratio (CTR). The method of 3f0 transmit phasing utilizes an additional 3f0 transmit signal to provide mutual cancellation between the frequency-sum compone...
