46. e A Howell Assistant Examiner Kim Kwok Chu Attorney Agent or Firm Arnold White amp Durkee 57 ABSTRACT A method and apparatus for storing and displaying radiographs particularly intra oral radiographs is pres ented Radiographs are captured digitized and dis played along with an icon of a portion of the anatomy from which the radiograph was taken The anatomical sites represented by the icon are arranged according to their normal anatomical relationship The icon is used by the system user to select a portion of the anatomy corresponding to the displayed radiograph and the radiograph is stored along with indicia of the selected anatomical site Then when the stored radiograph is desired to be viewed the icon is again displayed and the appropriate anatomical site is selected which causes the corresponding radiograph to be retrieved from stor age and displayed When processing intra oral radio graphs the icon can take the form of a dental film holder with the positions of the film holder corre sponding to anatomical sites readily recognized by den tists each position of the film holder being arranged in anatomical relation to other positions of the film holder icon An image of dentition for example a dental arch can also be used as an icon to facilitate the storage and display of intra oral radiographs 5 Claims 5 Drawing Sheets U S Patent Jan 12 1993 Sheet 1 of 5 5 179 579 22 PROGRAM LOAD
