  • Deformation imaging

    Creator:
    Margiocco, Marco L.
    Abstract:
    Recent developments in the field of clinical echocardiography allow the ultrasonographer to objectively quantify both regional and global myocardial function. Regional deformation (Strain) and deformation rate (Strain Rate) are novel indices of ventricular function that can be estimated non-invasively by ultrasonographic interrogation of the heart. Deformation Imaging (DI)represents a family...

  • Unique determination of acoustic properties from thermoacoustic data

    Creator:
    Hickmann, Kyle Scott
    Abstract:
    The extent to which thermoacoustic data determines the acoustic properties of an object was studied. In the case of one dimensional thermoacoustic imaging it was shown that constant acoustic profiles are uniquely specified from measurements. For a radial thermoacoustic problem we have shown that if the acoustic source is radial...
