Description

Einrichtung zur Bestimmung des Größenverhältnisses verschiedener Teile einer Röntgenaufnahme Der Gegenstand der Erfindung ist von besonderer Bedeutung für die Schädelforschung. Es ist an Hand von seitlichen Röntgenaufnahmen festgestellt worden, daß die Hypophyse beim Menschen fast immer im goldenen Schnitt zwischen dem Naseon (Nasenwurzel) und dem Ineon (Hinterkopf) liegt. Um aber Schlüsse aus ihrer Größe ziehen zu können, muß sie mit der Schädelgröße verglichen werden.Device for determining the proportions of different parts an X-ray image The subject matter of the invention is of particular importance for skull research. It is found on the basis of lateral x-rays that the pituitary gland in humans is almost always in the golden section between the Naseon (root of the nose) and the Ineon (back of the head). But to draw conclusions To be able to draw its size, it must be compared with the size of the skull.

Es ist an sich bekannt, zugleich mit dem Röntgenbild eines Objektes eine :Maßeinteilung auf die Bildschicht zu übertragen. Erfindungsgemäß wird nun das Maßnetz auf einer dünnen durchsichtigen Platte, z. B. aus Celluloid, mittels eines die Röntgenstrahlen absorbierenden Farbauftrags (beispielsweise Bleiweiß) hergestellt. Dadurch wird erreicht, daß das Maßnetz sowohl zum Abbilden durch die Röntgenstrahlen auf der Bildschicht zugleich mit dem Röntgenbilde des Objekts als auch zum nachträglichen Ausmessen fertiger Röntgenbilder verwendbar ist. Zweckmäßigerweise wird man die Platte in Form und Größe so wählen, daß sie in der Filmkassette untergebracht werden kann. Auch die Unterteilung wird man den in Frage kommenden Messungen anpassen. Bei einem Vergleich der Hypophyse mit dem Schädel empfiehlt sich ein Quadratmillimeternetz für das Gebiet der Hypophyse und ein Quadratzentimeternetz für den übrigen Schädel. Selbstverständlich kann die Einrichtung auch zu Vergleichsmessungen bei allen anderen Röntgenaufnahmen Verwendung finden.It is known per se, at the same time as the X-ray image of an object a: to transfer graduation to the image layer. According to the invention is now the measuring grid on a thin transparent plate, e.g. B. from celluloid, means an application of paint that absorbs the X-rays (e.g. white lead) manufactured. This ensures that the measurement network can be used both for mapping by the X-rays on the image layer at the same time as the X-ray images of the object can also be used for the subsequent measurement of finished x-ray images. Appropriately one will choose the plate in shape and size so that it is housed in the film cassette can be. The subdivision will also be adapted to the measurements in question. When comparing the pituitary gland with the skull, a square millimeter grid is recommended for the area of the pituitary gland and a square centimeter grid for the rest of the skull. Of course, the device can also be used for comparative measurements with all others Find X-rays use.
