  • Ultrasound diagnostic flow imaging with coded excitation
    Publication number: 20070038108
    Abstract: Diagnostic ultrasound flow imaging is performed with coded excitation pulses. Due to the use of frequency coded excitation pulses, flow information may suffer from spatial misregistration and estimate errors. Spatial position shift in flow data is offset for alignment with B-mode or other imaging. The flow estimates are compensated for the imaging center frequency variation with depth. The wide bandwidth information available due to coded excitation may allow anti-aliasing by estimating velocities from two frequency bands.

  • Ultrasound imaging enhancement methods and systems
    Patent number: 5961460
    Abstract: An ultrasonic imaging system generates Doppler and B-mode image signals, and then uses a modulated, non-linear mapping function to combine the Doppler and B-mode image signals into an output signal. In another mode of operation the imaging system generates fundamental and harmonic frequency intensity values and maps these intensity values to display indicia, preferably with a modulated, non-linear mapping function.
