ABSTRACT:
An ultrasound imaging system is provided with an adaptive filter for transforming an input signal to produce an output signal having one or more desired signal statistics (e.g., signal-to-noise ratio, Gaussian function specification, etc.). The adaptive filter includes a digital filter configured to receive input signals and produce output signals. The adaptive filter exhibits a transfer function H defined by one or more coefficients C. A controller is configured to generate the filter coefficients based upon one or more signal constraints that are provided to the controller by a user and a sample signal that exhibits one or more sample signal statistics and that is communicated to the digital filter. The controller communicates the filter coefficients to the adaptive filter. The filter coefficients cause the adaptive filter to transform input data, based upon the transfer function H(C), to produce output data exhibiting (at least approximately) the one or more desired signal statistics, the desired signal statistics based upon the sample signal statistics and the constraints. Several different coefficient sets may be utilized in the adaptive filter for different object parts (e.g., blood, tissue, etc.) to be imaged. Furthermore, the adaptive filter may be operated by a designer so as to preset the coefficients, periodically initiated by a user/operator to reset the coefficients, and/or automatically initiated by the system, perhaps periodically or upon detection of a certain event, during operation to reset the coefficients.
