  • Patent number: 9406411
    Abstract: An apparatus includes a portion that moves along a guided path and a displacement gauge that outputs readings based on the portion's position on the guided path. The apparatus additionally includes an intermediate limit switch that is activated in response to the portion being moved to an intermediate position on the guided path. The apparatus also includes a processing device configured to calibrate the apparatus based on a first reading corresponding to a first position on the guided path and a second reading corresponding to a second position on the guided path. The processing device verifies the calibration based on a third reading corresponding to the intermediate position.

  • Publication number: 20070086632
    Abstract: Storage and/or review of medical data are provided with interactive features of a video format. One or more examinations are stored in a DVD format. Using a standard format, standard equipment may be used to view the stored examinations. Interactive features of the video format allow navigation. Chapter selection allows choices of different examinations, patients or other information on the media. Parental controls are used to protect confidentiality. Measurements are available through selection of an overlay menu. Different views, renderings, annotations, measurements or other medical information are available by selecting of different recordings of the examination or image. Separate programs may not be needed to view the data. Other data may be stored in other formats for use by separate programs, such as storing DICOM information on a same media.

  • Patent number: 7044912
    Abstract: A method and system is disclosed which permits a user to save user defined viewing configuration, also referred to as a bookmark as a separately manipulatable or transferable entity without altering the underlying image data and maintaining, where desired, the association between the bookmark 200 and the underlying source image data. The disclosed system and method act to save the bookmark by saving the succession of system inputs, which, in conjunction with the system characteristics and system parameters, achieve the desired viewing configuration. Thereby, the disclosed system and method permits review of the inputs used to manipulate the image to confirm the process by which a diagnosis or anatomical measurement was made, permits the replay of a sequence for presentation or training purposes to effectively demonstrate not only the end result, but the methodology as well.

  • Publication number: 20050065823
    Abstract: The preferred embodiments described herein provide a method and system for monitoring confidential information in a medical records system. The monitoring may occur when the data is transferred in the medical records system, such as inputting data into the medical records system, outputting data from the medical records system, displaying data on the medical records system, or saving data in the medical records system. The method and system for monitoring confidential information may extract a portion of data transferred, compare the portion of data with a predetermined sequence in a database, determine whether the portion of data comprises patient information based on the comparison, and modify the portion of data if it comprises patient information. Extracting a portion of data may comprise parsing the data or may comprise reading a structured form. Further, comparing the portion of data with a predetermined sequence may comprise comparing the portion of data with a predetermined format.

  • Publication number: 20040204649
    Abstract: A method for migrating presets between medical diagnostic imaging system platforms is presented in which a preset for a first medical diagnostic imaging system platform is provided to a preset translator. The preset translator translates the preset to a second medical diagnostic imaging system platform, and the translated preset is implemented on a medical diagnostic imaging system comprising the second medical diagnostic imaging system platform. A system and method for sharing medical diagnostic imaging system presets are also presented. The system comprises a server and first and second medical diagnostic imaging systems in communication with the server. A medical diagnostic imaging system preset is sent from the first medical diagnostic imaging system to the server, and the preset is stored in the server.
