  • Systems and methods for image data management
    Patent number: 9153208
    Abstract: A system and method for image data management. A tiled representation of a data set is accessed. The tiled representation includes a plurality of high-resolution tiles and a plurality of reduced-resolution tiles. A request to access said data set from a computing device is received. An image display window is determined based on said request from the computing device, where the image display window corresponds to a displayable image for display on the display device. At least one overlapping image to send the computing device is determined based on said image display window, where the at least one overlapping image is selected from the scaled full images, the plurality of high-resolution tiles, and the plurality of reduced resolution tiles. At least a portion of the at least one overlapping image is sent to the computing device.
    Type: Grant
