Design und Erstellung einer graphischen Benutzerschnittstelle für medizinische Applikationen am Beispiel von Bildverarbeitungsalgorithmen zur digitalen Subtraktion von Röntgenbildern

Abstract

dc:description

Digital radiography opens new ways in diagnostic radiography, thus for example the digital subtraction of two radiographs. For the integration of such technologies into daily medical routine, not only fast computers are needed, but also suitable graphical user interfaces. The aim of the thesis is to create a solution for digital image radiography-subtraction to reach a large number of medical personnel with variable knowledge and skill and therefore improve diagnostics on a daily basis without installing specialized and complex computer hardware. Created was a web-based interface for digital subtraction radiography (DSR-Web) with corresponding database for image storage and retrieval. The subtraction of two digital radiographs can be processed using a variety of different subtraction algorithms. By choosing the Hypertext Markup Language (HTML) it is guaranteed that the DSR-Web is displayed identical on different computer systems and operating systems, thus being independent of hard- and software. HTML is used on many internet pages and provides a standardized platform to display test and graphics. Typical HTML-elements are lists, tables, diagrams, symbols and free text. In addition to presenting pure data and facts great importance was drawn to the presentation of the structural components like graphics and colors, because these contribute crucially to the acceptance and operability of the graphical user interface. For the basic color, the color "green" was chosen, for its general meaning of being reassuring and anti-depressive. For contrast and attention, the color "red" was chosen. The color red is usually described as a signaling color. It communicates the necessity to do something or to pay attention to the actual step. Finally the graphical user interface was tested according to its usability to show that it was learnable and usable. Introduced was the DSR-Web on the 14th International Congress on Dentomaxillofacial Radiology in June 2003 and over 700 subtractions by users out of more than ten countries were registered. Log file analysis showed that the DSR-Web fits the needs of medical personnel and therefore is applicable in daily medical routine.
