Abstract
An ultrasound system is disclosed. Embodiments in accordance with the present invention include a transducer configured to acquire pulse-echo data at each transmit frequency bandwidth of interest. In addition, a bandpass filter is configured to receive a signal of the pulse-echo data, wherein the signal is bandpass-filtered over a plurality of frequencies. Further, a processor is configured to calculate a spatial coherence of the bandpass-filtered signal. The spatial coherence of the signal is calculated in a spatial domain or a frequency domain. The spatial coherence is used to predict target conspicuity. The processor selects a preferred frequency based on and, preferably, to realize, the target conspicuity.
