ABSTRACT:
A method and apparatus for ultrasound imaging of Doppler energy-related parameters is described. An ultrasound imaging system includes a transducer for transmitting an ultrasound signal into a body and receiving a reflected ultrasound signal. The system determines the energy of the reflected signal from tissue within the body. Signal processing circuitry determines a Doppler intensity spectrum of the signal reflected from the tissue. The Doppler spectrum represents energy of the tissue-reflected signal as a function of Doppler frequency and time. Integration circuitry integrates the Doppler spectrum over Doppler frequency to determine the energy of the tissue-reflected signal as a function of time for display in strip mode. The system also determines an energy-velocity product. The integration circuitry may comprise circuitry for raising the Doppler intensity spectrum to a power m to generate a first spectral function and for raising a velocity-related function to a power n to generate a first velocity function. The integration circuitry integrates the product of the first spectral function and the first velocity function to determine the energy-velocity product function as a function of time.
