  • Publication number: 20190122401
    Abstract: A system and method for estimating vascular flow using CT imaging include a computer readable storage medium having stored thereon a computer program comprising instructions, which, when executed by a computer, cause the computer to acquire a first set of data comprising anatomical information of an imaging subject, the anatomical information comprises information of at least one vessel. The instructions further cause the computer to process the anatomical information to generate an image volume comprising the at least one vessel, generate hemodynamic information based on the image volume, and acquire a second set of data of the imaging subject. The computer is also caused to generate an image comprising the hemodynamic information in combination with a visualization based on the second set of data.

  • Patent number: 6819108
    Abstract: The present invention is directed to a method of shimming a magnet assembly of an MR imaging system such that a desired B0 field strength may be created with minimal inhomogeneities therethrough. With this method, sufficient shimming of the magnet assembly may be achieved without requiring mechanical variations to the magnet assembly after the magnet assembly has been assembled. The invention analyzes variations from the desired B0 field and inhomogeneities at a number of target points along the magnet assembly or B0 field. A comparison is then made at each point to determine a shimming or weighting factor such that the desired overall B0 field strength and targeted field homogeneity is achieved. Active and/or passive shim elements may then be incorporated into the magnet assembly at each target point to achieve the desired overall field strength and minimum overall field homogeneity.

  • Patent number: 6535775
    Abstract: A processor system and method for integrating a quality function deployment tool with a critical to quality tool is provided. Each of the tools is a computer-enabled tool. The method allows for executing quality function deployment at each of a plurality of levels with the quality function deployment tool for a system designable from a respective family of subsystem alternatives. The method further allows for generating quality matrices indicating a relationship between an original set of critical to quality characteristics and key control parameters with the critical to quality tool for the respective family of subsystem alternatives. A linking action allows for linking the quality function deployment tool to the critical to quality tool for tracking at each level the extent to which the original set of critical to quality characteristics is met by each respective family of subsystem alternatives.

  • Patent number: 6377908
    Abstract: A product design tradeoff method is provided. A transfer function, which generates an output in response to an input is obtained. A type of optimization to be performed is identified and the input to the transfer function is perturbed in order to achieve the type of optimization identified. Output information representing the output of the transfer function is then generated to provide the user with the result of the optimization. Generating the output information comprises generating a sensitivity matrix. The sensitivity matrix comprises a plurality of sensitivity values that indicates a relationship between a change in input versus a change in output, wherein each of the sensitivity values provides a corresponding numerical value for comparing an effect of the change in the input versus the change in the output.

  • Patent number: 6351680
    Abstract: An exemplary embodiment of the invention is directed to a method for performing quality function deployment for a system having a plurality of levels. The method includes obtaining a plurality of first level critical to quality parameters and obtaining a plurality of first level key control parameters. A first level quality matrix is generated identifying an effect at least one first level key control parameter has on at least one first level critical to quality parameter. The first level key control parameters are arranged into a first group and a second group. A second level quality matrix is generated for the first group. The second level quality matrix includes second level critical to quality parameters corresponding to the first group of first level key control parameters and a second level key control parameter. The second level quality matrix identifies an effect said second level key control parameter has on at least one second level critical to quality parameter.

  • Patent number: 6301516
    Abstract: A method of generating quality matrices indicating a relationship between critical to quality characteristics and key control parameters for levels of a process. A plurality of rows of a first matrix are designated as critical to quality characteristics and a plurality of columns of the first matrix are designated as key control parameters. Each critical to quality characteristic is assigned a critical to quality weight. An interaction weight is assigned between at least one critical to quality characteristic and at least one key control parameter. A score is then generated for at least one key control parameter in response to said critical to quality weight and said interaction weight.
