Description
Filter für Röntgenstrahlen. Die bei der therapeutischen Verwendung der Röntgenstrahlen zum Schutze des Patienten gegen weiche, leicht absorbierbare Strahlung angeordneten Filter bestehen allgemein aus metallischen Schichten in metallischer Fassung, sind also gute Leiter der Elektrizität. Da sie in der Nachbarschaft von Hochspannung führenden Apparaten verwendet werden, so treten vornehmlich infolge. Elektronenstrahlung, die von den durch die Röntgenstrahlen getroffenen Teilen ausgeht, Ladungen in ihnen auf, deren Stärke auch von der Größe des Filters abhängt. Da diese nicht unbeträchtlich ist, können Ladungen in solcher Stärke auftreten, daß ihr Ausgleich den Patienten erschrecken, dadurch belästigen und sogar zu unvorsichtigen Bewegungen veranlassen kann. Es erschien daher geboten, das Filter nichtleitend zu machen, während als Absorptionsmaterial des Filters doch ein leitender Stoff oder ein Metall verwendet werden sollte.X-ray filters. Those in therapeutic use of X-rays to protect the patient against soft, easily absorbable Filters arranged in radiation generally consist of metallic layers in metallic So they are good conductors of electricity. Since they are in the neighborhood of High-voltage equipment is used, so occur primarily as a result. Electron radiation emanating from the parts hit by the X-rays, Charges in them, the strength of which also depends on the size of the filter. This one is not inconsiderable, charges can appear in such strength that they are balanced frighten the patient, thereby annoying them and even making careless movements can cause. It therefore seemed advisable to make the filter non-conductive, while the absorption material of the filter is a conductive material or a metal should be used.
Diese Schwierigkeit wird gemäß der Erfindung dadurch vermieden, daß das Metall nicht in Form einer kompakten Masse, sondern als feines Pulver-in Isoliermasse eingebettet verwendet wird, so daß die Masse im ganzen nichtleitend ist. Zu dem gleichen Zweck kann auch der Rahmen aus isolierendem Material hergestellt werden.This difficulty is avoided according to the invention in that the metal not in the form of a compact mass, but as a fine powder in insulating mass embedded is used, so that the mass is non-conductive as a whole. In addition The frame can also be made of insulating material for the same purpose.
Beispielsweise kann man aus Aluminiumpulver und einer Masse aus Zeresin und Kolophonium eine Platte herstellen, die bei 8,5 mm Stärke dieselbe absorbierende Wirkung hat, wie eine Aluminiumplatte von x mm Stärke.For example, aluminum powder and a mass of ceresin can be used and rosin make a sheet that is 8.5 mm thick and absorbs the same Has the same effect as an aluminum plate x mm thick.
Es ergibt sich als weiterer Vorteil, daß die Durchlässigkeit der Platte durch Änderung der Menge des Metallpulvers sich ohne Schwierigkeit beliebig fein abstufen läßt.There is a further advantage that the permeability of the plate by changing the amount of metal powder it becomes as fine as desired without difficulty can be graded.
