Description
Vorrichtung für Serien und kinematographische Röntgenaufnahmen Es gibt eine Reihe von Vorrichtungen, die rasch aufeinanderfolgende Serienaufnahmen bezwecken, um einzelne Bewegungsphasen bewegter Organe, z. B. des Magens und Darms, röntgenphotographisch festzuhalten. Hierzu sind naturgemäß sehr kurzzeitige Aufnahmen notwendig, mit anderen Worten: die Verwendung von sogenannten Verstärkungsfolien ist nicht zu umgehen.Device for series and cinematographic x-rays Es are a number of devices that take rapid continuous shooting aim to separate individual phases of movement of moving organs, e.g. B. the stomach and intestines, to be recorded by X-ray photography. Naturally, these are very short-term recordings necessary, in other words: the use of so-called reinforcing foils cannot be avoided.
Es ist bereits ein Verfahren und eine Einrichtung zur indirekten Herstellung von Röntgenbildern bekannt, wonach ein Luminiszenzschirm belichtet und dieser gewissermaßen als erzeugende Platte benutzt wird, indem der nachleuchtende Luminiszenzschirm in Verbindung mit einem empfindlichen photographischen Papier gebracht wird, gegebenenfalls noch unter Erwärmen des Luminiszenzschirmes zur Verkürzung der Kopierzeit. Es wird also hierbei nur das Leuchten des L uminiszenzschirmes ausgenutzt.It is already a method and apparatus for indirect manufacturing known from X-ray images, according to which a luminescent screen exposes and this to a certain extent is used as a generating plate by placing the afterglow luminescent screen in In connection with a sensitive photographic paper, if necessary while heating the luminescent screen to shorten the copying time. It will thus only the glow of the luminescent screen is used here.
Es ist deshalb bereits ein dem gewöhnlichen Isinematographen nachgebildeter Apparat und die Benutzung eines Filmbandes für derartige Serienaufnahmen vorgeschlagen worden. Dabei ist die Verwendung von Verstärkungsschirmbändern erwogen, jedoch verworfen worden, .da der gleichzeitige Transport eines Filmbandes mit ein oder zwei Verstärkungsschirmbändern die Bewegung einer zu schweren Masse bedingt hätte.It is therefore already a model of the ordinary isinematograph Apparatus and the use of a film tape for such series recordings are proposed been. The use of reinforcing screen tapes is considered, but discarded since the simultaneous transport of a film tape with one or two reinforcing screen tapes would have caused a mass that was too heavy to move.
Die Erfindung schlägt, um diese Nachteile zu vermeiden, vor, an Stelle der verllältnismäßig schweren Verstärkungsschirme die leichten Verstärkungsfolien zu benutzen und diese zusammen mit dem Schichtträger zu verschieben zu dem Zwecke, die durch das Nachleuchten der Folie entstehenden Fehler zu vermeiden.In order to avoid these disadvantages, the invention proposes instead the relatively heavy reinforcement screens the light reinforcement foils to use and to move them together with the support for the purpose of avoid the errors caused by the afterglow of the film.
Der Erfindungsgegenstand ist auf der Zeichnung im Längsquerschnitt dargestellt.The subject of the invention is shown in the drawing in longitudinal cross-section shown.
B ist der erforderliche Strahlenschutz aus Bleiblech o. dgl. Statt der zwei einzelnen Verstärkungsfolien werden gemäß der Erfindung zwei Folienbänder V1 und V2 benutzt, die sich .gleichsinnig um die gleiche Strecke wie der zu belichtende Film P verschieben. Auf diese Weise kommen auf die neuen zu belichtenden Filmstrecken zwei neue, noch unbenutzte Strecken der Verstärkungsfolien zu liegen. Bis dann die schon benutzten Folienabschnitte für eine weitere Aufnahme im Fenster F wieder an die Reihe kommen, ist das Nachleuchten der bereits verwendeten Abschnitte längst wieder verschwunden.B is the required radiation protection made of lead sheet or the like. Instead of the two individual reinforcement foils become two foil strips according to the invention V1 and V2 used, which move in the same direction by the same distance as the one to be exposed Move film P. In this way, the new film sections to be exposed come on to lie two new, as yet unused stretches of the reinforcement foils. Until then already used film sections for a further exposure in window F again the series come, the afterglow of the sections already used has long been disappeared again.
