Description

Anordnung zur Berücksichtigung des absorbierenden Einflusses menschlicher Körperschichten bei der Intensitäts- und Härtemessung von Röntgenstrahlen. Bekanntlich berücksichtigt man Iden Ein-$uß verschieden starker Schichten des menschlichen Körpers auf Intensitäts- und Härtemessungen von Röntgenstrahlen dadurch, daß man in sogenannten Wasserphantomen die Messungen unter einer der Körperschicht der Stärke nach gleichen Wasserschicht vornimmt. Die bisherigen Wasserphantome ermöglichen dies für verschiedene Schichtdicken in der Weise, daß durch eine komplizierte Einrichtung eine kleine Meßkammer im Wasser in vertikaler Lage verschoben wird.Arrangement to take into account the absorbing influence of human Body layers in the intensity and hardness measurement of X-rays. As is well known one takes into account the influence of different layers of the human body on intensity and hardness measurements of X-rays by the fact that one in so-called Water phantoms are the measurements under one of the body layers of the same strength Layer of water. The previous water phantoms made this possible for various Layer thicknesses in such a way that a small one by a complicated device Measuring chamber is moved in the water in a vertical position.

Gegenstand vorliegender Erfindung ist eine einfache Vorrichtung, die einmal die Verwendung beliebig großer Meßanordnungen ermöglicht und ferner einen derartig komplizierten Einstellungsmechanismus vermeidet dadurch, daß die Meßeinrichtungen unter einem Gefäß angeordnet werden, das bis zur gewünschten Höhe mit Wasser gefüllt ist. Das Gefäß muß, wenigstens ;an der unmittelbar über der Meßeinrichtung liegenden Stelle, aus einem für Röntgenstrahlen leicht durchlässigen Material hergestellt sein.The present invention is a simple device that once allows the use of arbitrarily large measuring arrangements and also one such complicated adjustment mechanism avoids thereby that the measuring devices placed under a vessel that is filled with water to the desired height is. The vessel must, at least, be on the one directly above the measuring device Body, made of a material that is easily transparent to X-rays be.

Eine zweckmäßige Ausführungsform der vorbeschriebenen Einrichtung zeigt Abb. i. Das Absorptionsgefäß i, unter dem die Meßeinrichtung 2 angeordnet wird, steht durch einen Schlauch 3 in Verbindung mit einem anderen Gefäß ,4, durch dessen Heben und Senken jeder beliebige Wasserstand im Absorptionsgefäß eingestellt. werden kann. 5 stellt eine Einschiebevorrichtung für Härtefilter dar.An expedient embodiment of the device described above Fig. i shows. The absorption vessel i, under which the measuring device 2 is arranged is, is through a hose 3 in connection with another vessel, 4, through its raising and lowering set any water level in the absorption vessel. can be. 5 shows an insertion device for hardness filters.

PATENT-ANSPRÜCHE: i. Anordnung zur Berücksichtigung des absorbierenden Einflusses menschlicher Körperschichten bei der Intensitäts- und Härtemessung von Röntgenstrahlen, wobei die zu durchstrahlende Körperschicht durch eine gleich starke Wasserschicht ersetzt wird, dadurch gekennzeichnet, daß die zur Messung dienenden Geräte unmittelbar unter einem Gefäß angeordnet sind, das aus einem für Röntgenstrahlen leicht durchlässigen Material hergestellt und bis zu der durch die Dicke der Körperschicht gegebenen Höhe mit Wasser gefüllt ist. PATENT CLAIMS: i. Arrangement to take into account the absorbent Influence of human body layers when measuring the intensity and hardness of X-rays, whereby the body layer to be irradiated by an equally strong one Water layer is replaced, characterized in that the serving for measurement Devices are arranged directly under a vessel that consists of a X-ray Made of slightly permeable material and up to that through the thickness of the body layer given height is filled with water. 2. Anordnung nach Anspruch i, dadurch gekennzeichnet, daß die Höhe der Wassersäule im Absorptionsgefäß durch Heben bzw. Senken eines zweiten mit dem Absorptionsgefäß kommunizierenden Behälters verändert werden kann. 2. Arrangement according to claim i, characterized in that the height of the water column in the absorption vessel can be changed by raising or lowering a second container communicating with the absorption vessel.
