ABSTRACT:
A method and an apparatus for automating the B-mode transmit waveform center frequency/length adjustment based on actual image data. The average SNR and the spatial correlation statistics in selected kernels of the image data are analyzed to test if high-quality signal is present. By placing one or more of the test kernels at relatively great depth (i.e., close to the bottom of the user-selected image depth range), the overall test results indicate the highest-resolution transmit waveform that can be used, while providing a sufficiently strong signal down to the desired depth.
