Material für Röntgenaufnahmen. Patentiert im Deutschen Reiche vom 25. März 1923 ab. X-ray material. Patented in the German Empire on March 25, 1923.

Infolge des geringen Energieverlustes der Röntgenstrahlen beim Durchgänge durch das Aufnahmematerial kann man gleichzeitig mehrere selbständige photographische Schichten übereinandergelagert der Einwirkung derAs a result of the low energy loss of the X-rays when passing through the recording material can be seen at the same time several independent photographic layers superimposed on the action of the

anderliegende Schichten und exponiert wesentlich kurzer, als es unter normalen Verhältnissen nötig wäre,; so erhält man kongruente und in den Tonwerten gleiche, aber stark unterbelichtete Bilder. Zur Deckung gebracht geben sie in der Durchsicht ein einziges außerordentlich kräftiges Bild. Man kann somit die Expositionszeit auf einen Bruchteil der sonst üblichen herabsetzen, wasdifferent layers and exposed much shorter than it would under normal conditions would be necessary; in this way one obtains images that are congruent and have the same tone values, but are severely underexposed. For cover when viewed through, they give a single, extraordinarily powerful image. Man can thus reduce the exposure time to a fraction of what is otherwise usual

to in vielen Fällen von größter Bedeutung ist. Um die photographischen Schichten einander möglichst zu nähern, verwendet man einseitig oder zweiseitig mit photographischer Emulsion begossene Filme, aus denen man einen) Pack von gewünschter Schichtzahl bildet.to is paramount in many cases. To the photographic layers one another as close as possible, one uses one-sided or two-sided with photographic Emulsion-coated films from which a pack of the desired number of layers can be formed forms.

Gemäß der Erfindung werden die einzelnen Filme eines solchen Packs so zusammengehalten, daß sie sich nicht verschieben.According to the invention, the individual films of such a pack are held together in such a way that that they do not shift.

Man kann sich hierzu beispielsweise einer Randumklebung oder der verschiedenartigsten Rahmen, Klammern usw. bedienen (lAbb. 1 bis 4), die man vor dem Hervorrufen des Bildes öffnet oder entfernt. Vereinigt man die fertigen Einzelbilder wieder durch eine Haltevorrichtung, so gewinnt man das mehrschichtige Röntgenbild in handlicher Form.One can do this, for example, an edge wrapping or the most diverse Operate frames, brackets, etc. (lFig. 1 to 4), which can be opened or removed before the image is called up. If you unite the If you finish single images again through a holding device, then you win the multi-layered one X-ray image in a handy form.

An Stelle von lösbaren Haltevorrichtungen können die Filme durch fest mit ihnen verbundene Fake ο. dgl. vereinigt sein. Am einfachsten geschieht dies, indem man den Film selbst in geeigneter Weise faltet. Das Material für die Einzelbilder bildet dann ein einheitliches Stück, welches nur behufs Entwicklung us-w. auseinandergefaltet zu werden braucht (Albb. 5 bis 7). Durch Einklappen der Blätter bringt man ohne weiteres die Einzelbilder zur Deckung.Instead of releasable holding devices, the films can be firmly connected to them Fake ο. be united. The easiest way to do this is by watching the movie folds itself in a suitable manner. The material for the individual images then forms a uniform Piece, which only for the purpose of development etc. to be unfolded needs (albums 5 to 7). You can easily bring up the individual images by folding in the sheets for cover.

Außer den lichtempfindlichen Filmen kann der Pack die auch sonst in der Rönigenographie gebräuchlichen Verstärkungsschichten enthalten, welche mit dem Aufhahmematerial fest verbunden oder auf oder zwischen die Filme gelegt sein können. «In addition to the photosensitive films, the pack can also be used in other areas of roenigenography Common reinforcement layers that adhere to the absorbent material connected or placed on or between the films. «
