Beschreibung
Zusammenfassung:	A system and method are disclosed for capturing a radiographic or autoradiographic image of an object, in which a support member is provided to receive the object in an immobilized state; a phosphor screen is provided to transduce ionizing radiation from the source to visible light; film or a digital capture device is provided for capturing an image using the visible light; and the phosphor screen is moved incrementally to facilitate reduction of phosphor screen mottle. Cette invention concerne un système et un procédé permettant de capturer une radiographie ou une autoradiographie d'un objet, où un élément support est prévu de manière à recevoir l'objet dans un état immobilisé ; un écran de phosphore est prévu pour transmettre le rayonnement ionisant de la source à la lumière visible ; un film ou un dispositif de capture numérique est prévu pour saisir une image à l'aide de la lumière visible ; et l'écran de phosphore se déplace par incrément pour faciliter la réduction du voile de l'écran de phosphore.
