Abstract
Description
Die vorliegende Erfindung betrifft ein Magnetresonanzgerät mit einem Magneten und einer Zugangsöffnung.The The present invention relates to a magnetic resonance apparatus having a Magnets and an access opening.
Zur Durchführung von Magnetresonanzuntersuchungen ist es erforderlich, einen Patienten innerhalb eines starken Magnetfeldes zu platzieren. Dafür wird der Patient im Allgemeinen auf einer Patientenliege in die Mitte eines Magneten gefahren. Bei interventionellen Behandlungsmethoden, wie beispielsweise einer Katheterplatzierung innerhalb des Magnetresonanzgeräts, ist ein Zugang zum Patienten für den Arzt notwendig. Bei offenen Magneten, wie beispielsweise C-bogenförmigen Permanentmagneten, ist der Zugang des Arztes zum Patienten gewährt. Allerdings ist der behandelnde Arzt hier gezwungen, eine unbequeme Körperhaltung während der gesamten Untersuchungsdauer einzunehmen. So ist es für den Arzt nur schwer möglich, auf einem Stuhl vor dem Magnetresonanzgerät sitzend zum Patienten zu gelangen. Im Allgemeinen sind dabei der untere Teil des C-bogenförmigen Magneten und ein Unterbau des Magnetresonanzgeräts im Weg. Häufig ist der Arzt gezwungen, auf einem Kniestuhl vor dem Magnetresonanzgerät die Untersuchung durchzuführen.to execution From magnetic resonance examinations it is necessary to have a patient to place within a strong magnetic field. For this is the Patient generally on a patient couch in the middle of a Driven magnets. For interventional treatment methods, such as for example, a catheter placement within the magnetic resonance device is an access to the patient for the doctor necessary. For open magnets, such as C-shaped permanent magnets, is granted access of the doctor to the patient. However, the treating one is Doctor here forced an uncomfortable posture during the entire study period. So it is for the doctor difficult, sitting on a chair in front of the magnetic resonance device to the patient reach. In general, this is the lower part of the C-shaped magnet and a substructure of the magnetic resonance device in the way. Frequently the doctor forced on a kneeling chair in front of the magnetic resonance device to investigate perform.

Die Aufgabe der vorliegenden Erfindung ist es, ein Magnetresonanzgerät anzugeben, das eine bequeme Zugänglichkeit für einen Arzt während der Untersuchung ermöglicht.The The object of the present invention is to specify a magnetic resonance apparatus that is a convenient accessibility for one Doctor while the investigation allows.
Diese Aufgabe wird durch ein Magnetresonanzgerät mit den Merkmalen des Anspruchs 1 gelöst. Durch die Ausbildung eines Freiraums unterhalb des Magneten im Bereich einer Zugangsöffnung entsteht ausreichend Platz für den behandelnden Arzt, um seine Beine unterzubringen. So kann er seinen Stuhl sehr nah an das Magnetresonanzgerät bringen und so auf einfache Weise Zugang zum Patienten erlangen.These The object is achieved by a magnetic resonance apparatus having the features of the claim 1 solved. By forming a free space below the magnet in the area an access opening creates enough space for the attending physician to accommodate his legs. That's how he can do it bring his chair very close to the magnetic resonance device and so on easy Way to gain access to the patient.
In einer vorteilhaften Ausgestaltung der Erfindung umfasst das Magnetresonanzgerät einen Unterbau, wobei der Unterbau unterhalb des Magneten angeordnet ist und eine Aussparung aufweist, durch die der Freiraum gebildet ist.In According to an advantageous embodiment of the invention, the magnetic resonance apparatus comprises a Substructure, wherein the substructure is arranged below the magnet and a recess through which the clearance is formed.
In einer vorteilhaften Ausgestaltung der Erfindung ist der Unterbau als Standfuß ausgebildet. Dadurch ergibt sich eine besonders einfache Möglichkeit den Freiraum zu schaffen.In An advantageous embodiment of the invention is the substructure designed as a base. Thereby This results in a particularly easy way to create the free space.
In einer besonders vorteilhaften Ausführung der Erfindung weist der Standfuß eine Verjüngung auf. Dadurch bildet sich der Freiraum auf einfache Weise.In a particularly advantageous embodiment of the invention, the Stand one Rejuvenation on. As a result, the free space is formed in a simple manner.
In einer besonders vorteilhaften Ausführungsform der Erfindung weist der Magnet an einer dem Freiraum zugewandten Seite eine Einbuchtung auf. Dies schafft zusätzlichen Raum für die Oberschenkel des behandelnden Arztes, der dadurch seine Beine nahezu vollständig unter das Magnetresonanzgerät bringen kann.In a particularly advantageous embodiment of the invention the magnet on a side facing the free space on a recess. This creates additional room for the thighs of the attending physician, which causes his legs almost complete under the magnetic resonance device can bring.
Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich anhand des nachfolgend im Zusammenhang mit den beigefügten Figuren erläuterten Ausführungsbeispiels. Es zeigen:Further Advantages and embodiments of the invention will become apparent from the explained below in connection with the attached figures Embodiment. Show it:
Die Erfindung ist auch auf Magnete mit anderer Bauweise anwendbar, beispielsweise auf Magnete mit gespaltener C-Form oder H-Magnete. Bei derartigen C-Magneten ist der hintere Teil der C-Bogen gespalten, die Form von H-Magneten ähnelt einem geschlossenen C-Bogen.The Invention is also applicable to magnets of other construction, for example on magnets with split C-shape or H-magnets. In such C magnets is the back part of the C-arm split, the shape similar to H magnets a closed C-arm.
An Magnetresonanzgeräten der oben erläuterten Bauweise werden insbesondere interventionelle Behandlungsmethoden erheblich erleichtert. So findet der Arzt beispielsweise bei der Platzierung eines Katheters unter Magnetresonanz eine einfache Möglichkeit, ausreichend nah an den Patienten zu gelangen, ohne dabei auf eine bequeme Sitzposition oder Sitzhaltung verzichten zu müssen. Auch die Gabe von Kontrastmitteln während der Untersuchung gestaltet sich bei einem erfindungsgemäßen Magnetresonanzgerät bedeutend leichter als bei bekannten Geräten.At magnetic devices the above explained In particular, interventional treatment methods are used considerably relieved. For example, the doctor finds in the Placement of a catheter under magnetic resonance an easy way sufficiently close to the patient to get to without one to have to give up comfortable sitting position or sitting posture. Also the administration of contrast agents during The examination is significantly in a magnetic resonance apparatus according to the invention lighter than known devices.
