  • Title: [Imaging properties of digital image-intensifier radiography compared to the conventional x-ray technic for chest pictures].
    Author: Dölken W, Krahe T, Landwehr P, Lackner K.
    Journal: Rofo; 1989 Jan; 150(1):86-92. PubMed ID: 2536505.
    Abstract:
    Projection properties of a digital fluorographic system for chest examinations are examined using varying test phantoms. A maximal geometric distortion of +14% between the centre and the periphery of the image intensifier and a maximal spatial resolution of 2.6 LP/mm is found. Contrast detail diagrams are used to show the combination of spatial and contrast resolution of the system. Compared with diagrams for conventional radiographic systems there is a significant loss of resolution.
