Medical electrical equipment - Exposure index of digital X-ray imaging systems - Part 1: Definitions and requirements for general radiography
IEC 62494-1:2008 specifies definitions and requirements for the exposure index of images acquired with digital X-ray imaging systems. IEC 62494-1:2008 is applicable to digital X-ray imaging systems used in general radiography for producing projection X-ray images for general applications, such as, but not exclusively: - computed radiography (CR) systems based on stimulable phosphors; - flat-panel detector based systems; - charge-coupled device (CCD) based systems. Image intensifier based systems and systems for mammographic or dental application are not covered in this first edition. IEC 62494-1:2008 defines the exposure index only for images generated with a single irradiation event. Images generated from multiple irradiations (e.g., tomosynthetic or dual-energy images, multiple views on a single CR plate) are not covered.

La CEI 62494-1:2008 spécifie les définitions et les exigences pour l'indice d'exposition des images acquises avec des systèmes d'imagerie numérique à rayonnement X. La CEI 62494-1:2008 est applicable aux systèmes d'imagerie numérique à rayonnement X utilisés en radiographie générale pour produire des images radiologiques de projection pour les applications générales, comme par exemple, mais pas exclusivement: - les systèmes de radiographie assistée par ordinateur (CR, computed radiography) basés sur des luminophores stimulables; - les systèmes basés sur des détecteurs à écran plat; - les systèmes basés sur un dispositif à transfert de charge (CCD, charge-coupled device). Les systèmes basés sur un intensificateur d'image et les systèmes utilisés en mammographie ou pour les applications dentaires ne sont pas traités dans cette première édition. La CEI 62494-1:2008 définit l'indice d'exposition uniquement pour les images produites avec un seul événement d'irradiation. Les images produites à partir d'irradiations multiples (par exemple, images tomosynthétiques ou biénergétiques, vues multiples sur une seule plaque de radiographie assistée par ordinateur) ne sont pas traitées.
