Abstract
A radiography apparatus with which x-ray shadowgraphs are produced has a detector array in the form of a line or strip, and an x-ray radiator which is moved in a direction perpendicular to the line direction of the detector array for scanning a measuring field from different directions. The detector array accordingly receives x-radiation proceeding through the measuring field from different directions. A screen or slotted diaphragm having diaphragm shafts directed onto the detector array is disposed between the x-ray radiator and the measuring field, and blanks out x-radiation which is not useful for generating the shadowgraph image.
