Abstract (English)

A new method to reduce artifacts (MAR), produced by high-density objects, especially metal implants (MI), in X-ray CBCT is presented. MIs located in the field of view (FOV) result in artifacts influencing clinical diagnostics and treatments. The novel method reduces metal artifacts by virtually replacing MIs by tissue objects of the same shape. This corrected data can be reconstructed with ...

Die Arbeit präsentiert eine neue Methode zur Reduzierung von Artefakten (MAR), die durch Objekte mit hoher Elektronendichte, im Speziellen Metallimplantaten (MI), in Rekonstruktionen von Röntgen Kegelstrahl CT's. MI die im Sichtbereich (FOV) liegen beeinflussen die klinische Diagnostik und Behandlung durch Artefakte. Die präsentierte Methode reduziert diese Artefakte durch ein virtuelles Ersetzen ...
