Abstract
A system is disclosed for performing vibrational resonance ultrasonic Doppler spectrometry to produce characteristic vibrational resonance spectra of soft structures in compressible media or soft tissues in a living body. A system is further disclosed for vibrational resonance ultrasonic Doppler imaging of the spatial distribution of vibrational resonance properties. An audio-frequency source externally applies a sequence of vibrational frequencies into a medium or body. Ultrasonic pulsed Doppler beams are focused at various locations within a region of interest, and the received Doppler signals are used to estimate the amplitude of the vibrational resonance response at each location. A vibrational resonance spectrum is computed from received Doppler amplitudes at each vibrational frequency and graphically displayed. Mapping the vibrational resonance spectra of a plurality of regions of interest into colors and brightness according to specific curve shape criteria further generates a two-dimensional vibrational resonance image. These methods may be utilized in the detection and differentiation of tumors of the breast, prostate, liver, and other soft tissues.
