Method and apparatus for using Doppler modulation parameters for estimation of vibration amplitude










Image Number 14 for United States Patent #5086775.

A system for using Doppler modulation parameters for producing an estimation of the vibration amplitude of an object under investigation is disclosed in which a low frequency vibration source is used to force the oscillation of the object under investigation and a coherent or pulsed ultrasound imaging system is utilized to detect the spatial distribution of the vibration amplitude of the object in real-time. The reflected Doppler shifted waveform generated by reflecting the ultrasound waves off of the vibrating object under investigation is used to compute the vibration amplitude and frequency of the object using two alternative methods, either on a frequency domain estimator basis or on a time domain estimator basis.
