"WebPage 121. Chapter 7 Ultrasonics 7.1 Introduction. Ultrasound, as currently practiced in medicine, is a real-time tomographic imaging modality. Not only does it produce real-time tomograms of scattering, but it can also be used to produce real-time images of tissue and blood motion, elasticity, and flow in the tissue (perfusion).
