INTERACTIVE VIEWING, ASYNCHRONOUS RETRIEVAL, AND ANNOTATION OF MEDICAL IMAGES
Methods, apparatuses, and articles for interactive viewing, asynchronously retrieving and annotating medical images are described herein. In various embodiments, a client device may retrieve, from a server, a network resource having medical information and associated medical images, with the server initially including only a subset of the medical images. The client device may then facilitate a user in interactive viewing of the retrieved medical images, and asynchronously retrieve additional ones of the medical images from the server as the retrieved medical images are being interactively viewed. In some embodiments, in response to interactive viewing, the client device may request of a server a graphical primitive, the request specifying a graphical primitive type and information associated with the interactive viewing. In response the client device may receive the primitive and may create an annotation layer including the primitive associated with the medical image.
