Description
1. Beispiel1st example
Eine Verstärkerfolienkombination hoher Energieabhängigkeit — jeweils 120 mg/cm2 CaWo4 — Leuchtstoff für die vordere und hintere Verstärkerfolie mit rot eingefärbten Reflektor — bildet die Vergleichsfolie 1, die als Streifen gegenüber den Meßfolien bis7(Fig.~2)oderals Kreis bzw. Quadrat, umgeben von den Meßfolien (Fig. 3), angeordnet wird. Die Meßfolien 2 bis 7 können folgende Parameter haben: Strahlenqualität (Röhrenspannung) CaWO4-LeuchtstoffbelegungAn amplifier film combination of high energy dependence - 120 mg / cm 2 each CaWo 4 - phosphor for the front and rear intensifying screen with red colored reflector - forms the comparison film 1, which is a strip opposite the Meßfolien bis7 (Fig ~ 2) or as a circle or square, surrounded by the measuring sheets (Fig. 3) is arranged. The measuring foils 2 to 7 can have the following parameters: Beam quality (tube voltage) CaWO 4 phosphor coverage

Die Folien 1 bis 7 können in einer spezifischen Prüfkassette bzw. in jeder Aufnahmekassette so angeordnet werden, daß der Informationsgehalt der Röntgenaufnahmen nicht beeinflußt wird.The films 1 to 7 can be arranged in a specific test cassette or in each receiving cassette so that the information content of the X-ray recordings is not affected.
Auf einer oder jeder Meßfolie 2 bis 7 kann zusätzlich ein Filmstreifen mit keilförmig und/oder stufenweise abnehmender Transparenz angeordnet werden.On one or each measuring film 2 to 7, a film strip with wedge-shaped and / or gradually decreasing transparency can additionally be arranged.
2. Beispiel2nd example
2 nebeneinander angeordnete unterschiedlich mit CaWO4-Leuchtstoff belegte einzelne Verstärkerfolien werden je vor einem Fotoelement geschaltet und die Leuchtdichtedifferenz gemessen2 juxtaposed separately with CaWO 4 phosphor occupied individual amplifier films are each connected in front of a photo element and measured the luminance difference

1. 120 mg/cm2 1. 120 mg / cm 2
2. 10 mg/cm2 2. 10 mg / cm 2
Ein Meßgerät dieser Art könnte für den Service oder fest integriert in die Röntgenanlage eingesetzt werden.A measuring device of this type could be used for the service or permanently integrated in the X-ray system.
