Abstract

The diagnostic appts. includes a magnetic resonance system and a positioning device for the object under investigation, e.g. a patient. A light transmitter can be coupled to the positioning device at different positions. The light transmitter directs light via a fibre bundle towards the patient. The same portion of the patient can be illuminated regardless of the movement of the positioning device. The light source can be placed on different parts of the positioning device to illuminate different portions of the patient. The magnetic resonance system can be open or placed in a measurement tunnel.

Description

Insbesondere bei der Untersuchung eines Objektes mittels ei­ nes Magnetresonanzsystemes besteht häufig der Bedarf auch Licht zum Objekt zu führen, um somit einen Bereich auszu­ leuchten.Especially when examining an object using an egg There is often also a need for a magnetic resonance system To guide light to the object in order to cover an area to shine.

Aus der DE 42 25 433 C2 ist ein Magnetresonanzsystem mit ei­ ner außerhalb eines Meßtunnels angeordneten Lichtquelle be­ kannt, deren Licht über eine Lichtleiteranordnung aus Licht­ leitfasern einem flächenhaften Lichtaustrittsbereich im Meß­ tunnel zugeführt wird. Die Ankopplung einer vorzugsweise als Halogenlampe ausgebildeten Lichtquelle an die Lichtleiteran­ ordnung erfolgt über ein optisches Anschlußstück.DE 42 25 433 C2 describes a magnetic resonance system with an egg ner light source arranged outside a measuring tunnel knows whose light via a light guide arrangement of light fibers in the measurement area tunnel is fed. The coupling of a preferably as Halogen lamp trained light source to the light guide order is made via an optical connector.

Wird die Position des Objektes beispielsweise über eine Lage­ rungsvorrichtung verändert, so wird dann auch ein unter­ schiedlicher Bereich des Objektes beleuchtet. Dies ist nach­ teilig, da die Beleuchtung dann so verändert werden muß, daß der ursprüngliche Bereich wieder beleuchtet wird.For example, the position of the object is about a location tion device changed, then also under different area of the object is illuminated. This is after part, because the lighting must then be changed so that the original area is illuminated again.

Aufgabe der Erfindung ist es daher, eine medizindiagnostische Untersuchungseinrichtung der eingangs genannten Art so aus zu­ führen, daß bei einer Ortsveränderung des Objektes keine Nachführung der Beleuchtung erfolgen muß.The object of the invention is therefore a medical diagnostic Examination device of the type mentioned at the outset cause that when the object changes location The lighting must be updated.

Die Aufgabe wird erfindungsgemäß durch den Gegenstand des Pa­ tentanspruches 1 gelöst.The object is achieved by the subject of Pa claim 1 solved.

Vorteil der Erfindung ist, daß durch die Ankopplung der Lichtsendeeinrichtung an die Lagerungsvorrichtung auch bei einer Ortsveränderung der Lagerungsvorrichtung immer derselbe Bereich beleuchtet wird, so daß eine Nachführung nicht mehr erforderlich ist. Advantage of the invention is that by coupling the Light transmitter to the storage device also a change of location of the storage device always the same The area is illuminated so that tracking is no longer possible is required.  

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispie­ les anhand der Zeichnung in Verbindung mit den Unteransprü­ chen.Further advantages and details of the invention emerge from the following description of an exemplary embodiment les based on the drawing in conjunction with the dependent claims chen.

In der Figur ist ein in prinzipieller Weise dargestelltes Ma­ gnetresonanzsystem mit dem Bezugszeichen 1 gekennzeichnet. Diesem Magnetresonanzsystem 1 ist eine Lagerungsvorrichtung 2 für ein Untersuchungsobjekt 3 zugeordnet, die räumlich ver­ stellbar ist. Das Licht einer Lichterzeugungseinrichtung 4 wird über ein Faserbündel 5 zu einer Lichtsendeeinrichtung 6 geleitet, die an die Lagerungsvorrichtung 2 angekoppelt ist. Es ist somit möglich, auch bei einer Ortsveränderung der La­ gerungsvorrichtung 2 immer denselben Bereich des Untersu­ chungsobjektes 3 zu beleuchten. Vorzugsweise ist die Licht­ sendeeinrichtung 6 an unterschiedliche Stellen an die Lage­ rungsvorrichtung 2 ankoppelbar, so daß auch unterschiedliche Bereiche des Objektes 3 gegebenenfalls beleuchtet werden kön­ nen. Es hat sich als besonders vorteilhaft erwiesen, wenn ein Bereich der Lichtsendeeinrichtung 6 über einen Schwanenhals (7) geführt und somit das Licht an einen vorbestimmten Ort der Lagerungsvorrichtung 2 geleitet werden kann. Das Magne­ tresonanzsystem 2 kann, wie dargestellt, als offenes System ausgeführt sein oder aber auch einen Meßtunnel aufweisen.In the figure, a magnetic resonance system shown in a basic manner is identified by the reference number 1 . This magnetic resonance system 1 is assigned a storage device 2 for an examination object 3 , which is spatially adjustable. The light from a light generating device 4 is guided via a fiber bundle 5 to a light emitting device 6 , which is coupled to the storage device 2 . It is thus possible to always illuminate the same area of the examination object 3 even when the storage device 2 changes location. Preferably, the light emitting device 6 can be coupled to the location device 2 , so that different areas of the object 3 can also be illuminated, if necessary. It has proven to be particularly advantageous if an area of the light emitting device 6 is guided over a gooseneck ( 7 ) and the light can thus be directed to a predetermined location of the storage device 2 . The magnetic resonance system 2 can, as shown, be designed as an open system or else have a measuring tunnel.

Vorzugsweise weist sich die Schwanenhalslampe durch die spe­ ziellen Eigenschaften aus, daß sie nicht leitend ist und aus keinem ferromagnetischen Material besteht. Ferner ist sie au­ toklavierbar oder kann mit einem Plastiküberzug versehen sein, so daß eine sterile Bedienung der Lampe möglich ist.Preferably, the gooseneck lamp points through the spe particular properties that it is not conductive and from there is no ferromagnetic material. It is also au toclavable or can be provided with a plastic cover be so that sterile operation of the lamp is possible.
