ABSTRACT:
An ultrasound imaging system that utilizes a short sinusoidal pulse burst for excitation, and performs coherent detection of the reflected signal, resulting in improved signal-to-noise ratio. In addition, the polarity of the rate of change of parameters, principally density, is preserved by the coherent detection. This allows a density versus distance signal to be reconstructed by integrating the coherently detected signal. The system includes components to calculate and apply all necessary phase corrections.
