  • Process for converting triglycerides to hydrocarbons
    Patent number: 7550634
    Abstract: Processes for the conversion of hydrocarbons boiling in the temperature range of from about 80° F. to about 1000° F. to diesel boiling range hydrocarbons, and processes for increasing the cetane number and amount of n-C17 hydrocarbon products in such processes. Diesel boiling range hydrocarbons may be produced by contacting a hydrocarbon boiling in the above-mentioned boiling range with a triglyceride-containing compound to form a mixture, and then contacting the mixture with a hydrotreating catalyst under suitable reaction conditions.

  • Determination of feature boundaries in a digital representation of an anatomical structure
    Patent number: 7454045
    Abstract: A virtual anatomical structure can be analyzed to determine enclosing three-dimensional boundaries of features therein. Various techniques can be used to determine tissue types in the virtual anatomical structure. For example, tissue types can be determined via an iso-boundary between lumen and air in the virtual anatomical structure and a fuzzy clustering approach. Based on the tissue type determination, a deformable model approach can be used to determine an enclosing three-dimensional boundary of a feature in the virtual anatomical structure. The enclosing three-dimensional boundary can be used to determine characteristics of the feature and classify it as of interest or not of interest.

    Patent number: 7440601
    Abstract: Portions of a virtual colon can be analyzed to identify a normal structure, such as an ileocecal valve. Paradigmatic characteristics of ileocecal valves can be used to identify a digital representation as an ileocecal valve. Upon determination that a digital representation has the characteristics of an ileocecal valve, action can be taken. For example, the digital representation can be removed from a list of polyp candidates.
