System and method for visual annotation and knowledge representation
A method and system for visually annotating an image. Annotations and notes to images, such as digital medical and healthcare images, may be stored in a structured vector representation alongside image information in a single, non-volatile and portable file or in a separate file from the image. The annotations may be composed of point, line and polygon drawings and text symbols, labels or definitions and captions or descriptions. The annotations may be structured in a manner that facilitates grouping and manipulation as user defined groups. The annotations may be related to an image but not inextricably bound such that the original image is completely preserved. Annotations may further be selectively displayed on the image for context appropriate viewing. The annotations may be retrieved for purposes such as editing, printing, display, indexing and reporting for example, and may be displayed on an image for interactive use with an embedded self-contained user interface.

19. The method of claim 18 , further comprising presenting the symbol or the label adjacent the defined region of interest in the user interface based on a user selection.
20. The method of claim 18 , wherein the textual information further includes a caption.
21. The method of claim 1 , further comprising receiving pointer information associated with the received information, wherein an annotation further comprises the received pointer information.
22. The method of claim 21 , wherein the received pointer information includes secondary information related to the received information.
23. The method of claim 22 , further comprising presenting the secondary information in the user interface based on activation of a hot-spot associated with a pointer created in the user interface based on the received pointer information.
24. The method of claim 1 , further comprising:
receiving second information defining a second region of interest identified by the user interacting with the presented digital image;
receiving second textual information associated with the received second information, wherein a second annotation comprises the received second information and the received second textual information; and
associating the annotation and the second annotation with a first annotation group.
25. The method of claim 24 , further comprising:
receiving a selection of the first annotation group to present overlaid on the displayed digital image; and
presenting the digital image with the annotation and the second annotation.
26. A device for visually annotating a digital image, the device comprising:
a processor; and
a computer memory operably coupled to the processor, the computer memory comprising programming code that, upon execution by the processor, performs operations comprising
presenting a digital image in a user interface of a display;
receiving information defining a region of interest identified by a user interacting with the presented digital image;

presenting the digital image overlaid with the received information and the received textual information;
presenting a plurality of annotation indicators in the user interface, an annotation indicator of the plurality of annotation indicators including the received textual information associated with the annotation;
receiving a selection of a first annotation indicator of the presented plurality of annotation indicators; and
presenting the digital image without the received information and the received textual information associated with the received selection.
27. The device of claim 26 , wherein the programming code further performs operations comprising:
receiving second information defining a second region of interest identified by the user interacting with the presented digital image;
receiving second textual information associated with the received second information, wherein a second annotation comprises the received second information and the received second textual information; and
associating the annotation and the second annotation with a first annotation group.
28. The device of claim 27 , wherein the programming code further performs operations comprising:
receiving a selection of the first annotation group to present overlaid on the displayed digital image; and
