  • Patent number: 7187790
    Abstract: A technique is provided for offering feedback, including feedback for patient care and for training purposes for medical professionals and human operators. The technique includes accessing data, such as image data, for evaluation by a human operator. The data is then analyzed via a computer-assisted data operating algorithm, and the analysis may further include analysis of supplemental data accessed from an integrated knowledge base. Based upon the analysis feedback is provided to the operator, such as for completing or complementing the evaluation, correcting analysis by the human operator, or otherwise informing the human operator of similarities or differences between the analyses.

  • Patent number: 6795526
    Abstract: A method and system for of defining, or identifying, regions of interest for exposure management in a digital x-ray imaging system, and especially in the case of multiple consecutive image acquisitions. According to the most basic embodiment of the present invention, simple geometric shapes arranged in a matrix configuration are used to aid an operator in identifying a region of interest for a diagnostic x-ray image. Each region of interest is selectable from a low-dose preshot image and may be corrected, or processed, in order to enhance the results of a subsequent diagnostic image. The processing of the preshot image allows the system to automatically make predictions for the diagnostic image exposure requirements, thereby avoiding unnecessary multiple images.

  • Publication number: 20040122704
    Abstract: An integrated knowledge base of medical-related data is accessed by a variety of users and resources for providing data on user-specific, function-specific and similar bases. The integrated knowledge base may be located physically at a range of disparate locations, as may the users and resources. Based upon factors such as the user identification, the user type, the user function, the user environment, and so forth, the system can provide specifically-adapted interfaces for interacting with the integrated knowledge base. Similarly, controlled access may be provided on similar bases such that some but not all of the data or functionality of the integrated knowledge base is offered to the specific user. Interfacing with resources, such as diagnostic equipment and systems is also provided, and can be similarly customized and access-controlled.

  • Publication number: 20040122702
    Abstract: Access, analysis and processing medical-related data in an integrated knowledge base is initiated by one of a plurality of initiating events, such as a user query, the occurrence of a medical event, a change of state of data within the knowledge base, and a system-generated initiating event, such as based upon attaining various triggering levels or expiration of. The integrated knowledge base may be physically located in quite disparate locations, and processing strings may occur on one or more computer system. The triggering events begin specific processing based upon algorithms which can respond to the specific triggering event, or can analyze data in manners not necessarily requested by the triggering event. The technique thus permits analysis of a wide range of medical-related data for user-related purposes, patient-related purposes, as well as to identify and discover particular medical care needs or relationships between data to enhance diagnosis, treatment, institutional performance, and so forth.

The data is processed in conjunction with data from an integrated knowledge base to provide recommendations and information to enhance efficiency of the provision of medical care and diagnosis. The recommendations may include additional procedures to be performed prior to or during the patient contact. Patient-specific information, including procedures and educational information, may be crafted based upon the patient's data and the additional data from a variety of resources. Reports and guidance may be provided prior to, during or following the patient contact both for the patient, an institution, and physicians and clinicians.
