    摘要: The present invention relates to a method for aligning an object, whose image is to be recorded, with an image capture apparatus and a coupling eyepiece. Said method consists in using a light source, said light source being positioned in the place of the object and emitting luminous dots through a mask and through the coupling eyepiece towards the capture apparatus. The invention also consists in verifying whether the images of said luminous dots are split into two on the image plane, then, using all the development functions determined for the various alignment settings, in determining a particular setting in which the distances between the images of the luminous dots are minimal.

    摘要: The cameras (10) of this X-ray detector are all mounted on a common rigid plate (1) by a surface support and screwed to ensure their optical distance from a scintillator (7) itself mounted on the plate (1) by an enclosure (6) forming a darkroom (8). The common mounting of the principal elements of the detector on a single rigid plate thus significantly reduces image deterioration produced by deformations of the detector, of thermal or mechanical origin.
