Abstract

The modulation transfer function for an elliptical tomographic scan is derived. Its imaging characteristics are compared with those of linear and circular scans

Key words

Tomography Transfer function Imaging system 

Sommaire

La fonction de transfert de modulation d'un balayage tomographique elliptique est dérivée dans cet article. Ses caratéristiques d'image sont comparées avec celles des balayages circulaires et linéaires.

Zusammenfassung

Die Modulationsaustauschfunktion einer elliptischen tomographischen Abastung wird abgeleitet. Ihre Abbildungsmerkmale werden mit denen von linearen und runden Abtastungen verglichen.
