Description

Verfahren zur röntgenologischen Darstellung von Organbewegungen mittels feststehender Schlitze und Bildbewegung Bekannt ist die Röntgenkymographie, bei welcher hinter einem feststehenden, strahlendurchlässigen Schlitz ein Schichtträger senkrecht zur Schlitzrichtung verschoben wird, so daß der sich im Schlitz bewegende Randschatten als Kurve zur photographischen Darstellung kommt. Auch die gleichzeitige Anwendung mehrerer Schlitze ist bekannt. Der Zweck ist die Festhaltung der jeweils gleichzeitigen Bewegung verschiedener Organe. Der Nachteil solcher Kymogramme lag jedoch darin, daß wohl die Bewegung einzelner herausgegriffener Punkte festgehalten wurde, die Gesamtbewegung des Organes aber nicht rekonstruierbar war. Das Verfahren nach der Erfindung ermöglicht dies. Zu diesem Zweck muß eine Vielzahl von Schlitzen so eng aneinander stehen, daß die Kontinuität, wie bei der zeichnerischen Konstruktion einer Kurve, erhalten bleibt. Die Bewegung des Schichtträgers wird dann von einem Schlitz zum andern durchgeführt. Das Prinzipielle an dem Verfahren ist die Verteilung der Schlitze auf eine große Fläche, die Häufung derselben und die Einhaltung eines solchen Schlitzabstandes, daß aus den Einzelpunkten das Gesamtorgan noch konstruiert werden kann. Beim Herzen ist z. B. ein Abstand von t bis 2 cm nötig, um aus den Randpunkten ein vollständiges Herzbild zu erhalten. Bei der Orthodiagraphie ist die Aufnahme einzelner Randpunkte zur Rekonstruktion der gesamten Herzfigur allgemein üblich und man verwendet auch hier diesen ungefähren Abstand von r bis 2 cm. Die Orthodiagraphie berücksichtigt aber nicht die Veränderung der Herzform während der Aktion. Mit dem neuen Verfahren ist es möglich, bei Herzfernaufnahmen sowohl die Herzgröße bei der Systole wie bei der Diastole, die ja bekanntlich oft von r bis 2 cm schwanken, auf dem Film festzuhalten. Dies bedeutet natürlich eine außerordentliche Verfeinerung der gesamten Herzmessung. Prinzipiell wäre es ja nur nötig, eine Herzaktion zur Darstellung zu bekommen; praktisch zeigt sich aber, daß auch bei nur z cm Verschiebung 2 bis 3 Flerzaktionen deutlich dargestellt werden können. Eine Ausführungsform zeigt beispielsweise Fig. r und 2. a ist der Brennpunkt einer Röntgenröhre, b eine Bleiplatte mit den ausgesparten Schlitzen c, d, e, f usw., g eine Kassette mit eingelegtem Film, welche in der Richtung des Pfeiles während der Aufnahme durch irgendeine mechanische Vorrichtung, wie Uhrwerk, untersetzter Elektromotor usw., langsam verschoben wird.Method for the radiological representation of organ movements by means of fixed slits and image movement X-ray kymography is known, in which behind a fixed, radiolucent slit a layer carrier is displaced perpendicular to the slit direction, so that the edge shadow moving in the slit comes as a curve for the photographic representation. The simultaneous use of several slots is also known. The purpose is to keep track of the simultaneous movement of different organs. The disadvantage of such kymograms, however, was that the movement of individual selected points was recorded, but the overall movement of the organ could not be reconstructed. The method according to the invention makes this possible. For this purpose, a large number of slots must be so close to one another that the continuity, as in the graphic construction of a curve, is preserved. The movement of the support is then carried out from one slot to the other. The principle of the method is the distribution of the slots over a large area, the accumulation of these and the maintenance of such a slot spacing that the entire organ can still be constructed from the individual points. With the heart z. B. a distance of t to 2 cm is necessary to get a complete heart image from the edge points. In orthodiagraphy, it is common practice to record individual edge points to reconstruct the entire heart shape, and this approximate distance of r to 2 cm is also used here. However, the orthodiagraphy does not take into account the change in the shape of the heart during the action. With the new method, it is possible to record the size of the heart during systole and diastole, which, as is well known, often fluctuates from r to 2 cm, on the film. This of course means an extraordinary refinement of the entire heart measurement. In principle, it would only be necessary to get a heart action to display; in practice, however, it has been shown that even with a displacement of only z cm, 2 to 3 Flerz actions can be clearly displayed. An embodiment is shown, for example, in FIGS. R and 2. a is the focal point of an X-ray tube, b a lead plate with the recessed slots c, d, e, f etc., g a cassette with an inserted film, which in the direction of the arrow during recording is slowly moved by some mechanical device such as clockwork, reduced electric motor, etc.

PATENTANSPRUCH: ". Verfahren zur röntgenologischen Darstellung von Organbewegungen mittels feststehender Schlitze und Bildbewegung, dadurch gekennzeichnet, daß die Schlitze jeweils gleichen Abstand voneinander haben, der so bemessen ist; daß das Gesamtbild des aufzunehmenden Organes aus den jeweiligen Einzelpunkten in seiner Gesamtgestaltung erkennbar ist, so daß aus den gewonnenen Kurven wiederum die Gesamtbewegung des Organes erkannt werden kann.PATENT CLAIM: ". Method for the radiological representation of Organ movements by means of fixed slits and image movement, characterized in that the slots each have the same distance from one another, which is so dimensioned; that the overall picture of the organ to be recorded from the respective individual points in its overall design is recognizable, so that again from the curves obtained the overall movement of the organ can be recognized.
