Description
Verfahren zur Darstellung, Kenntlichmachung, Sichtbarmachung bzw. Aufzeichnung von Strukturen innerhalb des menschlichen oder tierischen Körpers Zur Darstellung und Kenntlichmachung von im Innern eines. Gegenstandes, insbesondere jedoch des menschlichen und tierischen Körpers gelegenen Tçilen, z. B. Organen u. dgl., wird üblicherweise so verfahren, daß mit Hilfe von Strahlen, die den Körper durchdringen, z. B. Röntgen- oder Gammastrahlen, ein Schattenbild der Körperteile erzeugt wird, dessen Entstehung auf der verschiedenartigen Durchlässigkeit der einzelneu Körperteile für die verwendete Strahlung beruht.Procedure for representation, identification, visualization or Recording of structures within the human or animal body For Representation and identification of the inside of a. Subject, in particular however, the human and animal body located Tçilen, z. B. organs u. Like., The procedure is usually so that with the help of rays that the body penetrate, e.g. B. X-rays or gamma rays, a silhouette of the body parts is created, the emergence of which is based on the various types of permeability of the individual u Body parts for the radiation used is based.
Diesem Schattenverfharen haftet de rNachteil an, daß häufig die Durchlässigkeit einzelner Organe so wenig verschieden ist, daß im Schattenbild eine schlechte Differenzierung erreicht wird, so daß Kontrastmittel in bekannter Weise angewendet werden müssen. This shadow process has the disadvantage that it is often the permeability individual organs are so little different that in the shadow image there is poor differentiation is achieved, so that contrast media must be used in a known manner.
Ferner ist es bekannt, zur Sichtbar fachung mehr oberflächlich gelegener Körperteile, z. B. Venen, Ultrarotstrahlen zu benutzen, deren Durchdringung größer ist als die des sichtbaren Lichtes und die infolge verschiedener Remission durch die einzelnen Körperteile ebenfalls eine differenzierte Ablbildung derselben auf dem beispielsweise photographisch aufgenommenen Ultrarotbild ergibt. It is also known to more superficially located to the visible fold Body parts, e.g. B. veins to use ultrared rays, their penetration greater is than that of visible light and that due to different remission the individual parts of the body also have a differentiated image of the same results in the ultrared image taken, for example, photographically.
Dieses Verfahren wiederum ist in seiner anwendbarkeit durch die verhältnismäßig geringe Eindringtiefe dieser Strahlen begrenzt. This procedure, in turn, is proportionate in its applicability limited depth of penetration of these rays.
Radioaktive Stoffe, die für ähnliche Zwecke ebenfalls bekannt sind und verwendet werden, kommen für den menschlichen und tierischen Organismus wegen der schädigenden Wirkungen nicht in Frawge. Radioactive substances that are also known for similar purposes and used, come because of the human and animal organism the adverse effects not in Frawge.
Es ist ferner bekannt, rachitische Küken mit künstlich aktiviertem Phosphor zu behandeln, um festzustellen, wie sich der Phosphor in den erkrankten Knochen im Gegensatz zu denjenigen gesunder Küken erteilt. It is also known to have rachitic chicks with artificially activated Treat phosphorus to determine how the phosphorus is in the sick Bones in contrast to those of healthy chicks.
Zu diesem Zwecli wurden die Küken 22 Stunden nach der Injektion geschlachtet, die Knochen isoliert und dann eine photographische Aufzeichung der Knochen mit Hilfe der Strahlung des dort abgelagerten künstlich aktivierten Phosphors gemacht. Im unversehrten Körper fand jedoch keine Durchleuchtung mit der aktivierten Substanz statt.For this purpose, the chicks were slaughtered 22 hours after the injection, isolate the bones and then use a photographic record of the bones the radiation of the artificially activated phosphorus deposited there. in the However, the intact body was not fluorinated with the activated substance instead of.
Hier wurde lediglich eine aktivierte Substanz eingeführt, die zu den Aufbaustoffen eines bestimmten Körperteiles der Knochensubstanz gehört. Ferner wurde keine Durch leuchtung unmittelbar nach der Injektion am lebenden Körper vorgenommen, sondern der betreffende Körperteil, in den die Substanz erst später hineingewandert ist, wurde entfernt und für sich behandelt.Here only an activated substance has been introduced, which contributes to the The building blocks of a certain part of the body belong to the bone substance. Furthermore, was no fluoroscopy performed on the living body immediately after the injection, but the part of the body in question into which the substance later migrated is, has been removed and treated for itself.
Erfindungsgemäß bringt man in den menschlichen oder tierischen Körper zur Kenntlichmanchung der Struktur Substanzen ein, die durch vorherige Bestrahlung könstlich radioaktiv gemacht wurden, eine nicht schädigende radioaktive Integraldosis ausstrahlen und deren Zerfallsprodukt nicht radioaktiv ist, worauf deren Strahlung ohne irgendeinen Eingriff in den Organismus mit Hilfe von Fluoreszenzschirmen, photographischen Schichten oder elektrischen Anzeigegeräten sichtbar gemacht wird. Die emittierte Strahlung dient also dazu, unmittelbar nach der Injektion die Struktur von Organteilen sichtbar zu machen. Beim photographischen Verfahren kann man sich noch eines Verstarkerschirmes bedienen. Bei den elektrischen methoden wird das bei dieser Strahlung auftretende elektrische Feld bzw. die ionisierende Wirkung der Strahlen ausgenutzt. According to the invention, it is introduced into the human or animal body In order to identify the structure, substances that were previously irradiated were made royally radioactive, a non-damaging radioactive integral dose radiate and whose decay product is not radioactive, whereupon their radiation without any intervention in the organism with the help of fluorescent screens, photographic Layers or electrical display devices is made visible. The emitted Radiation therefore serves to restore the structure of parts of organs immediately after the injection to make visible. In the photographic process one can still use an intensifier screen serve. With the electrical methods, this is what occurs with this radiation electric field or the ionizing effect of the rays exploited.
Solche künstlichen radioaktiven Substanzen besitzen vor allen Dingen den Vorteil, daß sie den Körper durch ihre Strahlung nach erfolgter photographischer Aufnahme o. dgl. nicht mehr schädigen, da ihre Aktivität verbältnismäßig schnell ablclingt. Außerdem l. aml man zur Aktivierung Substanzen benutzen, die völlig ungiftig und der Körper substanz verwandt sind. Sie üben dann überhaupt keinen störenden Einfluß aus. Such artificial radioactive substances possess above all things the advantage that they are the body through their radiation after photographic No more damage to intake or the like, since their activity is relatively fast decays. Besides, l. aml to use substances that are completely non-toxic for activation and the body substance are related. You then do not practice any disruptive activity at all Influence off.
Die zu verwendenden Substanzen werden daher zweckmäßig so gewählt, daß ihre radioaktive Wirkung scher rasch abklingt bzw. ihre gesamte radioaktive Strahlung einen nicht schädigenden Integralwert hat, so daß keine Strahlenschädigung bei einer Ablagerung der Substanz im Körper auftreten kann. Ferner ist es zweckmäßig, die Stoffe so zu wählen, daß sie zur Aufnahme der Körper ohne Schädigung geeignet sind. Insbesondere eignet sich hierfür radioaktives Natrium, das in Form von physiologischer Kochsalzlösung injiziert wird. The substances to be used are therefore expediently chosen so that that their radioactive effect wears off quickly or their total radioactive effect Radiation has a non-damaging integral value so that no radiation damage can occur if the substance is deposited in the body. It is also advisable to to choose the substances so that they are suitable for the body to absorb without harm are. Particularly suitable for this is radioactive sodium, which is in the form of physiological Saline solution is injected.
