Abstract
Description
Die Erfindung betrifft ein Computertomographiegerät mit einer Halterung und einer an der Halterung angeordneten Gantry, welche relativ zu der Halterung um eine Kippachse kippbar gelagert ist.The invention relates to a computed tomography device with a holder and a gantry arranged on the holder, which is mounted tiltable relative to the holder about a tilting axis.
Computertomographiegeräte der dritten Generation weisen eine Gantry mit einem stationären Teil und einem relativ zu dem stationären Teil um eine Systemachse der Gantry rotierbaren Teil auf. Der rotierbare Teil hat die Form einer Trommel, an der Komponenten des Computertomographiegerätes wie die Röntgenstrahlenquelle, der Röntgenstrahlendetektor, ein Steuerungssystem etc. angeordnet sind, welche sich im Betrieb des Computertomographiegerätes um einen längs der Systemachse in einem Messfeld angeordneten Patienten drehen.Third generation computed tomography devices include a gantry having a stationary portion and a portion rotatable about a system axis of the gantry relative to the stationary portion. The rotatable part is in the form of a drum on which components of the computed tomography apparatus such as the X-ray source, the X-ray detector, a control system, etc. are arranged, which rotate during operation of the computed tomography device about a patient arranged along the system axis in a measuring field.
Für bestimmte Untersuchungen von Patienten ist es erforderlich, die Gantry mit dem Röntgenmesssystem um eine im Wesentlichen rechtwinklig zu der Systemachse angeordnete, im Wesentlichen horizontal verlaufende Kippachse relativ zu einem Standfuß zu kippen bzw. zu schwenken. Der Kippwinkel beträgt in der Regel maximal ca. +/–30° aus der Ausgangslage heraus.For certain examinations of patients, it is necessary to tilt or pivot the gantry with the X-ray measuring system about a substantially horizontally extending tilting axis, arranged substantially at right angles to the system axis, relative to a pedestal. The tilt angle is usually a maximum of +/- 30 ° out of the starting position.
Wie in
Der Erfindung liegt die Aufgabe zugrunde, ein Computertomographiegerät der eingangs genannten Art derart auszuführen, dass es möglichst zu keinen Verspannungen verursacht durch die Lagerung der Gantry kommt.The invention has for its object to perform a computed tomography device of the type mentioned in such a way that it comes as possible to no tension caused by the storage of the gantry.
Nach der Erfindung wird diese Aufgabe gelöst durch ein Computertomographiegerät, aufweisend eine Halterung und eine an der Halterung angeordnete Gantry, welche Gantry relativ zu der Halterung um eine Kippachse kippbar gelagert ist, wobei die Gantry nur an einer Seite und/oder nur an einer Stelle über ein Lager an der Halterung angeordnet ist.According to the invention, this object is achieved by a computed tomography device, comprising a holder and a gantry arranged on the holder, which gantry is tiltably mounted relative to the holder about a tilting axis, the gantry only on one side and / or only at one point a bearing is arranged on the holder.
Die Erfinder schlagen also vor, die Gantry nur einseitig mit nur einem Lager gegen die Halterung kippbar zu lagern. Durch die einseitige Lagerung der Gantry kann es zu keinen Verspannungen der Gantry bei Kippbewegungen der Gantry um die Kippachse kommen.The inventors thus propose to tilt the gantry only one side with only one bearing against the bracket. Due to the one-sided mounting of the gantry there can be no tension of the gantry during tilting movements of the gantry about the tilting axis.
Nach einer Variante der Erfindung ist die Halterung ein Standfuß bzw. Sockel oder eine Wand eines Gebäudes oder eine an der Wand eines Gebäudes angeordnete Tragevorrichtung. Die Gantry kann also über das Lager direkt oder indirekt an der Wand eines Gebäudes oder über das Lager an einer beispielsweise säulenförmigen oder andersartigen Tragevorrichtung angeordnet sein, welche Tragevorrichtung an der Wand eines Gebäudes angeordnet ist.According to a variant of the invention, the holder is a base or a wall or a wall of a building or arranged on the wall of a building carrying device. The gantry can therefore be arranged via the bearing directly or indirectly on the wall of a building or via the bearing on an example columnar or other type carrying device, which carrying device is arranged on the wall of a building.
Nach einer weiteren Variante der Erfindung ist der Standfuß bzw. Sockel des Computertomographiegerätes L-förmig ausgebildet.According to a further variant of the invention, the pedestal or base of the computed tomography device is L-shaped.
Nach einer Ausgestaltung der Erfindung weist der L-förmige Standfuß bzw. Sockel des Computertomographiegerätes einen horizontal verlaufenden Abschnitt und einen vertikal verlaufenden Abschnitt auf, wobei das Lager in oder an dem vertikal verlaufenden Abschnitt angeordnet ist. Dieser Aufbau benötigt weniger Bauraum bzw. beansprucht weniger Raumvolumen des das Computertomographiegerät aufnehmenden Raumes, da im Vergleich zu dem eingangs beschriebenen Aufbau nach dem Stand der Technik ein vertikal verlaufender Abschnitt des Standfußes bzw. Sockels entfällt. Auf diese Weise wird auch die Zugänglichkeit zu dem Computertomographiegerät bzw. dem Messfeld der Gantry, in dem ein Patient bei Messaufnahmen angeordnet ist, insbesondere von der der Lagerung gegenüberliegenden Seite verbessert.According to one embodiment of the invention, the L-shaped base of the computed tomography device has a horizontally extending portion and a vertically extending portion, wherein the bearing is arranged in or on the vertically extending portion. This construction requires less space or less space occupied by the computed tomography device receiving space, since compared to the structure described above according to the prior art, a vertically extending portion of the pedestal or base omitted. In this way, the accessibility to the computed tomography device or the measuring field of the gantry, in which a patient is arranged at measuring exposures, in particular improved from the opposite side of the storage.
Nach einer Ausführungsform der Erfindung ist das Lager als Festlager ausgeführt. Beispielsweise lässt das Festlager keine Normal- und Tangentialbewegungen des Lagers zu.According to one embodiment of the invention, the bearing is designed as a fixed bearing. For example, the fixed bearing does not permit normal and tangential movements of the bearing.
Gemäß einer weiteren Ausführungsform der Erfindung verläuft die Kippachse des Computertomographiegerätes im Wesentlichen horizontal und vorzugsweise rechtwinklig zu der Systemachse des Computertomographiegerätes.According to a further embodiment of the invention, the tilting axis of the computed tomography device extends substantially horizontally and preferably at right angles to the system axis of the computed tomography device.
