摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
