摘要： An analysis system and method provide for quantitatively evaluating image quality characteristics of an ultrasound imaging machine that evaluates at least one image representation of a standard phantom acquired by the image machine. The machine under test by comparing acquired parameters with prestored values, and returning a determined set of image quality indices, along with a single index representing an arithmetic combination of all other image quality indices, which indicate the accuracy of the test image relative to a “gold standard” that has been pre-established for the model of imaging machine under investigation. The system, which includes a computer-programmed set of instructions and data, optionally includes at least one standard phantom. The image quality indices, or metrics, quantitatively represent an evaluation of a test image using a set of relatively subjective criteria that include homogeneity, contrast, signal attenuation and penetration of depth, pin to background ratio in near and far-field, axial and lateral resolution, modulation transfer function, and geometric distortion, and axial and lateral linearity. These image quality indices are determined by specific algorithms and then combined to form an image health index. The image health index and the individual component indices are compared to a gold standard set of indices obtained from an equivalent imaging machine operating under optimum conditions and settings.

摘要： This invention provides a system and method for integrating a plurality of diagnostic information from a multiple of sources. In this invention, there is a site specific database which contains site specific information for a machine. A plurality of diagnostic related information is obtained from the machine. A diagnostic router collects the site specific information for the machine and the plurality of diagnostic related information and generates a current incident record therefrom. An approved incident record database contains a plurality of approved incident records obtained from a plurality of machines. An integrator finds approved incident records from the approved incident record database that most closely match the current incident record.
