Browser-based interface to ontology-driven imaging atlas. (a) Drop-down menus (top) provide a mechanism for selecting structures by category and name (the subclavian artery has been selected in this example). Image annotations are shown in the atlas in blue, with the currently selected structure highlighted in brighter opaque blue and other available annotations shown in darker transparent blue. (b) Any available annotation may be selected by moving the cursor over the structure of interest (the coracoclavicular ligament has been selected in this example). Annotations may be toggled on and off to more fully reveal the underlying imaging appearance. Additional information about a structure of interest may be obtained by means of a pop-up menu, which is invoked with the right mouse button. (c) Pop-up menu for the supraspinatus muscle with attachment information derived from RadLex.
