Zusammenfassung

Mit der zunehmenden Digitalisierung der Thoraxradiographie wird ein robuster, für die klinische Routine geeigneter Algorithmus zur Segmentierung des Lungenparenchyms notwendig. Der hier vorgestellte Algorithmus stellt ein semi-automatisches Verfahren dar, bei dem durch einen lokal-adaptiven Kantendetektor das Lungenparenchym segmentiert wird. Durch iterative Schätzung des Kantenverlaufs wird eine richtungsabhängige Skalierung und Gradientenbildung erreicht. Die Parametrisierung der Kurvenkrümmung erlaubt eine Anpassung an das zu segmentierende Objekt.
