Paper Abstract

In many hospitals, radiological examinations are scheduled via a Radiology Information System (RIS) or Picture Archiving and Communication System (PACS) before the imaging is performed. Demographic and examination information is first entered into the PACS database; when the images are later acquired, they have to match up with the correct pre-scheduled exam. This problem is non-trivial because patients may be scheduled for several exams on the same modality on the same day, and older modalities are unable to identify unambiguously the type of examination being performed. The purpose of this work is to develop practical and reliable strategies to assist in matching up the correct exam. Three potential solutions are considered: (1) modifications to imaging hardware and/or software, which force a PACS- generated exam ID into the image headers at acquisition time and thus guarantee a perfect match; (2) profiling algorithms, which attempt to find a match based on information already contained within the image headers; and (3) interactive Modality Examination Terminals (METs), which query the PACS database and assist human operators in manually selecting an appropriate exam. Solution (1) was found to be impractical with our existing digital imaging equipment, therefore solutions (2) and (3) were implemented and evaluated. Configuration files read at start-up time permitted the same hardware to be operated in either profiling or true MET mode. For each digital imaging modality the most appropriate mode of operation was determined, maintaining as far as possible a consistent hardware and software user interface.
