Radiological image intensifier tube with dyed porous alumina layer |
摘要 |
The disclosure relates to radiological image intensifier tubes, and more particularly to means to improve the image resolution of these tubes and/or correct their brightness curve at output. The image intensifier tube comprises an input screen comprising a scintillator borne by an aluminium substrate. A porous layer of alumina is interposed between the scintillator and the substrate. The alumina layer is dyed so as to absorb the light emitted by the scintillator towards the substrate.
