Fluoreszenzschirm für Röntgenzwecke. Patentiert im Deutschen Reiche vom 28. November 1913 ab.Fluorescent screen for X-ray purposes. Patented in the German Empire on November 28, 1913.

Die Erfindung betrifft Fluoreszenzschirme, wie sie in der Röntgentechnik als Durchleuchtungs- oder Verstärkungsschirme zur Verwendung gelangen.The invention relates to fluorescent screens, as used in X-ray technology as fluoroscopic or intensifying screens are used.

Gemäß der Erfindung wird ' die Wirksamkeit des Schirmes dadurch erhöht, daß die unter, der Einwirkung der Röntgenstrahlen fluoreszierende Masse auf einer spiegelnden Fläche angeordnet ist. Es werden demzufolgeAccording to the invention, the effectiveness of the screen is increased in that the under, the action of X-rays fluorescent mass on a specular Area is arranged. It will be accordingly

ίο die von der fluoreszierenden Masse ausgehenden und auf die Fläche fallenden Fluoreszenzstrahlen an dieser reflektiert. Hierdurch erhöht sich die Intensität des Fluoreszenzlichtes und damit dessen Wirksamkeit auf das Auge oder die photographische Platte.ίο those emanating from the fluorescent mass and fluorescent rays incident on the surface are reflected therefrom. This increases the intensity of the fluorescent light and thus its effectiveness on the eye or the photographic plate.

Die spiegelnde Fläche wird zweckmäßig aus einem Stoff hergestellt, der Sekundärstrahlen in hohem Maße und vorzugsweise solche von geringerer Durchdringungsfähigkeit aussendet.The reflective surface is expediently made of a substance, the secondary rays emits to a high degree, and preferably, those of lower penetrability.

Es wird dabei die die fluoreszierende Masse tragende, mit der spiegelnden Oberfläche versehene Unterlage aus einem weichen, sekundäre Strahlungen aussendenden Metall geringen Atomgewichtes, z. B. Aluminium oder Kupfer, hergestellt. Auch kann man Metalle hohen Atomgewichtes verwenden, sofern diese, wie z. B. Silber, neben den harten Strahlen auch eine weiche, sekundäre Strahlung aussenden. It becomes the one that carries the fluorescent mass and is provided with the reflective surface Base made of a soft metal of low atomic weight which emits secondary radiation, e.g. B. aluminum or Copper, manufactured. Metals with a high atomic weight can also be used, provided that they such as B. silver, in addition to the hard rays also emit a soft, secondary radiation.

Es sind bereits Verstärkungsschirme in Vorschlag gebracht worden, bei denen die fluoreszierende Masse auf Metallplatten, welche für Röntgenstrahlen undurchlässig oder fast undurchlässig, sind, wie z. B. aus Blei, Zinn, Kupfer oder Bleiglas, aufgetragen war. Bei diesen bekannten Schirmen ist von der fälschlichen Annahme ausgegangen, daß Körper hohen spezifischen Gewichtes oder vielmehr hohen Atomgewichtes eine weiche Sekundärstrahlung aussenden, während das Gegenteil der Fall ist. Im übrigen sind derartige Schirme für Durchleuchtungszwecke unverwertbar.Intensifying screens have already been proposed in which the fluorescent Mass on metal plates, which are opaque or almost impermeable to X-rays, are, such as B. made of lead, tin, copper or lead glass was applied. These known umbrellas are wrong Assumption assumed that bodies of high specific weight or rather high atomic weight emit soft secondary radiation send out while the opposite is true. In addition, such umbrellas are unusable for fluoroscopy purposes.
