| 摘要 |
<p>The invention relates to ionizing radiation sensors such as X rays or η rays, used in industrial or medical radiographic imaging systems. Such sensor (1) is comprised of a charge transfer array device (20) coupled to a scintillator element (51, 52) and filtering means to impede the passage of radiations which have not been transformed by said scintillator element. It is characterized in that said filtering means are comprised of the association of the non-optical element consisting of a beam of tubular guides (40), which are totally or partly metallic, and of said scintillator element, said scintillator element being housed in the non-optical element. Applications particularly in the field of intraoral dental radiology.</p> |
