A system and method for performing an ultrasound may include generating a set of continuous tone signals for injection into an object. A corresponding set of reflected tone signals in the frequency domain may be received The set of reflected tone signals may be converted from the frequency domain to the time domain to create a set of time domain signals. At least one region of interest may be identified from the set of time domain signals. A window may be defined around the identified region of interest in the set of time domain signals. The windowed time domain signals may be converted from the time domain to the frequency domain to create a set of windowed frequency domain signals. At least one characteristic parameter may be calculated from the set of windowed frequency domain signals. Information may be output based on the calculate at least one characteristic parameter.
