Abstract

Billedskjerm med materiallag (1), som har ei inngangsflate (la) for mottak av røntgenstråler (R) i røntgenstråle-avbildning, og med ei utgangsflate (lb) på den motstående sida av materiallaget, hvor et bilde som fanges opp optisk blir dannet. For å skape bildet er det områder (2) med et materiale som sender ut lys fra områdene (2) ved røntgenstråle-effekt, der områdene (2) er tilstøtende hverandre i skjermplanet, og plassert mellom inngangsflata (la) og utgangsflata (lb) i tykkelsesretningen til materiallaget. Områdene (2) er atskilt fra hverandre i skjermplanet for å gi en bedre romlig oppløsning. Langsgående akser (Z) til områdene (2) som strekker seg ut i tykkelsesretningen til n.ateriallaget er anordnet i forskjellige innfallsvinkler (a) med skjermplanet, slik at innfallsvinklene øker fra midten av skjermen mot kantene, slik at forlengelser på de langsgående aksene (Z) løper sammen mot den sentrale akse (A). Oppfinnelsen vedrører også en framgangsmåte for å tilvirke en billedskjerm for røntgenstråle-avbildning.
