  • Patent number: 7280702
    Abstract: A dynamic transfer syntax efficiently transfers data, including large data images, from a server to at least one client. Source data is transformed into a hierarchical representation. The hierarchical representation, consisting of essentially non-redundant data, is a plurality of levels of transform data, such that a level of the hierarchical representation comprises transform data sufficient to reconstruct the source data at a resolution corresponding to the level. The server transfers transform data from a level of the hierarchical representation corresponding to a desired resolution. To render a new view of the source image at the client, the client requests from the server coefficients of the transform data necessary to reconstruct the new view. In response to the request, the server transfers to the client the additional transform data, and the client reconstructs the new view from the coefficients transferred. A medical imaging application for the dynamic transfer syntax is disclosed.

  • Patent number: 7058901
    Abstract: A navigation rectangle controls display of medical images in a multi-display system. Multiple thumbnail sized medical images are displayed on a control panel. Each navigation rectangle encompasses one or more thumbnail size medical images on the control panel. In turn, images, corresponding to the thumbnail size medical images encompassed by the navigation rectangle, are displayed on a monitor that corresponds to the navigation rectangle. The user may fully move the navigation rectangle to select any images within an exam, and the user may resize the navigation rectangle to include or exclude images. The user may move images in and out of the navigation rectangle.

  • Patent number: 6938211
    Abstract: An image transfer object is disclosed that provides the necessary mechanism to conduct a dynamic transfer operation. The image transfer object includes a static reference to dynamic data. The image data is “dynamic”, in that the user may request additional views of the image. An image recipient computer receives the static reference to identify a source image on a server, and generates a first request, based on the static reference, for a view of the source image to the server. In response, the server transmits data to the image recipient computer. The image recipient computer displays the first view of the source image for viewing by the user. The user may then select a different portion of the source image, and/or a different resolution to designate a second view of the source image. The image recipient computer generates a second request to the image server for the second view, and the image server transmits additional data to generate the second view of the source image.

  • Patent number: 6734880
    Abstract: A user interface for a medical informatics system, which permits a physician to work with digitized medical images in a manner that the physician is accustomed to working with traditional analog film, is disclosed. The user interface includes a through a patient browser view to provide the ability to select studies, which consist of medical images and series, for patients. After selecting the studies, the user, through a patient canvas view, may then organize the studies as well as the images/series within the studies, including resizing the studies and the images/series within a study. The user may also pan and zoom images to view portions of an image at various resolutions. Furthermore, the user of the user interface may analyze the image by selecting to view the image in detail in a large floating window.

  • Patent number: 6556724
    Abstract: An image collaboration system conducts resolution independent image collaboration among a host computer and participating client computers. The subject of the image collaboration involves at least one source image. The source image is transformed into a hierarchical representation, such that each level of the hierarchical representation is sufficient to reconstruct the source image at a given resolution. The host computer displays, at a first resolution, an image based on one or more of the source images. To conduct the resolution independent image collaboration, the host computer generates a resolution independent description of the image, which describes the first display image relative to the source image, and broadcasts the resolution independent description of the image to the participating clients. In response, the participating clients generate an image from the resolution independent description of the image at the host computer at a resolution sufficient for display at the participating clients.
