Paper Abstract

An important component of a radiologist's workload is the "reading" of radiographs and the accompanying reporting process which normally involves dictation and verification of the subsequent transcription. A subset of the patient radiographic file is chosen by the radiologist and arranged on viewboxes (typically a set of 8 viewboxes arranged in two rows of 4). The radiologist reads this subset of films and reports his findings in the context of the accompanying requisition statement. One can distinguish two distinct preliminary phases in the "analog" reading process. The first phase deals with the film selection and placement on the viewboxes (image organization), and the second with the actual film reading (involving image navigation, i.e. the means for accessing the individual images). Our multimedia radiological workstation which will replace the viewboxes by a low-resolution Control Monitor, and a single high-resolution Image Monitor for viewing the radiographic images. The set of radiographic images of the patient are organized by body area and examination view, and are associated with a sketch of a human body on the Control Monitor. This "anthropomorphic" organization of the images helps the radiologist create a mental picture of the entire patient radiographic file. We expect that together with the requisition information, a proper representation of the file will improve the search for relevant radiographic images. The workstation supports image navigation by means of a "soft" representation of the physical viewboxes. In the same manner that radiographic films can be placed onto physical viewboxes, image labels can be dragged with the mouse onto soft viewboxes embedded on the Image Monitor. Evaluation of results from tests conducted with 15 physicians are presented.
