  • Publication number: 20070147672
    Abstract: In one aspect, the invention is a method of medical image processing. The method includes receiving data representing a medical image. The method also includes generating the medical image based on a model. The model characterizes the medical image as a composition of at least two components having processing constraints.

  • Publication number: 20070148139
    Abstract: A method and materials to create complex vascularized living tissue in three dimensions from a two-dimension microfabricated mold has been developed. The method involved creating a two dimensional surface having a branching structure etched into the surface. The pattern begins with one or more large channels which serially branch into a large array of channels as small as individual capillaries, then converge to one or more large channels. The etched surface serves a template within a mold formed with the etched surface for the circulation of an individual tissue or organ. Living vascular cells are then seeded onto the mold, where they form living vascular channels based on the pattern etched in the mold. Once formed and sustained by their own matrix, the top of the mold is removed. The organ or tissue specific cells are then added to the etched surface, where they attach and proliferate to form a thin, vascularized sheet of tissue.

  • Publication number: 20070147696
    Abstract: In one aspect, the invention is a method to reduce a blooming effect of a bright object in a medical image generated from a low-dose imaging system. The method includes characterizing an ideal image as a composition of a first component and a second component. The first component is characterized by a first function and the second component is characterized by a second function. The method also includes minimizing the first function and the second function using a smoothing process and generating the medical image based on the minimizing.

  • Patent number: 7217574
    Abstract: Performing high-resolution determination of the relative shift of the spectral properties of a biosensor. The shift in the resonance peak of the biosensor is indicative of the amount of material bound to the surface of the biosensor. A preferred biosensor is a Guided Mode Resonant Filter Biosensor (GMRFB). In one aspect of the invention, curve fitting is used to determine the relative location of the spectrum of the unexposed biosensor with respect to those spectra that are altered (e.g., shifted) by the presence of materials bound to the surface of the biosensor. In an alternative embodiment, the cross correlation function is used to detect spectral peak offsets between a reference spectrum and a spectrum measured from an exposed biosensor. In yet another alternative, maximal likelihood estimation techniques are used to determine the spectral shift or offs.
