Abstract
Description
Die Erfindung betrifft eine Patientenliege, welche insbesondere für die Lagerung eines Patienten bei der Computertomographie oder Magnetresonanztomographie geeignet ist. Weiter betrifft die Erfindung ein Verfahren zum Testen eines ein bildgebendes Diagnosegerät sowie eine Patientenliege umfassenden medizintechnischen Diagnosesystems unter Verwendung eines Phantoms. The invention relates to a patient bed, which is particularly suitable for the storage of a patient in computed tomography or magnetic resonance tomography. The invention further relates to a method for testing a medical diagnostic system comprising an imaging diagnostic device and a patient couch using a phantom.
In bildgebenden medizintechnischen Verfahren wie der mit Röntgenstrahlung arbeitenden Computertomographie oder der Magnetresonanztomographie können nach dem Stand der Technik sogenannte Phantome zum Test des betreffenden Diagnosesystems, welches neben dem bildgebenden Gerät, das heißt insbesondere Computertomographen beziehungsweise Magnetresonanztomographen, typischerweise auch eine Patientenliege umfasst, verwendet werden. Das Phantom befindet sich während des Tests in der Regel in geometrisch definierter Relation zur Patientenliege. In imaging medical technology methods such as working with X-ray computed tomography or magnetic resonance tomography so-called phantoms for testing the relevant diagnostic system, which in addition to the imaging device, ie in particular computed tomography or magnetic resonance imaging, typically also includes a patient bed, can be used in the prior art. The phantom is usually in a geometrically defined relation to the patient couch during the test.
Aus der
Die
Der Erfindung liegt die Aufgabe zugrunde, das Testen und Kalibrieren von bildgebenden medizintechnischen Diagnosesystemen gegenüber dem genannten Stand der Technik weiterzuentwickeln, insbesondere rationell zu gestalten. Diese Aufgabe wird erfindungsgemäß gelöst durch eine Patientenliege mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zum Testen eines medizintechnischen Diagnosesystems mit den Merkmalen des Anspruchs 10. Im Folgenden im Zusammenhang mit der Patientenliege erläuterte Vorteile und Ausgestaltungen gelten sinngemäß auch für das Verfahren und umgekehrt. Der Begriff "Testen" ist in einem weiten Sinn zu verstehen und schließt insbesondere Prozeduren ein, die im Stand der Technik im Zusammenhang mit bildgebenden Diagnosegeräten als "Kalbibrieren" oder "Justieren" bezeichnet werden. Charakteristisch für die als "Testen" bezeichnete Prozedur ist, dass sie unter Verwendung eines als "Phantom" bezeichneten Gegenstandes mit bekannten Eigenschaften und/oder bekannter Anordnung statt des eigentlichen Untersuchungsobjekts, insbesondere Patienten, durchgeführt wird. The invention has for its object to further develop the testing and calibration of medical imaging diagnostic systems with respect to the cited prior art, in particular to make rational. This object is achieved by a patient bed with the features of
Die erfindungsgemäße Patientenliege weist ein vorzugsweise verstellbares Liegenbrett sowie ein integriertes Phantom auf. Das Phantom ist insbesondere für Bildqualitäts- und Dosisprüfungen nutzbar und zur Verwendung bei Prüfabläufen vorgesehen, welche beispielsweise täglich oder in größeren Zeitabständen, zum Beispiel monatlich, durchgeführt werden. The patient couch according to the invention has a preferably adjustable couch board and an integrated phantom. The phantom is particularly useful for image quality and dose testing and intended for use in test procedures which are performed, for example, daily or at longer intervals, for example, monthly.
Gemäß einer ersten Ausführungsform ist das Phantom fest am Liegenbrett, insbesondere an dessen Stirnseite, montiert. Das Phantom ist dabei derart gestaltet, dass es in allen Betriebszuständen des Diagnosesystems an seinem relativ zum Liegenbrett festen Ort verbleiben kann und insbesondere die Untersuchung eines auf dem Liegenbrett liegenden Patienten nicht beeinträchtigt. According to a first embodiment, the phantom is firmly mounted on the bed, in particular on its front side. The phantom is designed such that it can remain in its fixed relative to the couch board in all operating conditions of the diagnostic system and in particular does not affect the investigation of a patient lying on the couch board.
Gemäß einer zweiten Ausführungsform ist das Phantom automatisiert am Liegenbrett befestigbar sowie von diesem abnehmbar. In diesem Fall ist vorzugsweise eine Mehrzahl an Phantomen vorhanden, welche wahlweise automatisiert am Liegenbrett befestigbar sowie von diesem abnehmbar sind. Zur Aufbewahrung der Phantome ist ein Speicherbehälter vorgesehen, welcher – vergleichbar mit einem Werkzeugmagazin – in einen das Liegenbrett tragenden Sockel der Patientenliege integriert sein kann. According to a second embodiment, the phantom is automatically fastened to the couch board and removable from this. In this case, a plurality of phantoms is preferably present, which can optionally be fastened automatically to the bedstead and can be removed therefrom. For storing the phantoms, a storage container is provided which - comparable to a tool magazine - can be integrated into a base of the patient bed carrying the bed base.
Eine gemäß dieser Ausführungsform gestaltete Patientenliege, welche zusammen mit einem bildgebenden Diagnosegerät, insbesondere Computertomographen oder Magnetresonanztomographen, ein medizintechnisches Diagnosesystem bildet, ermöglicht einen ein Phantom nutzenden Testlauf des Diagnosesystems mit folgenden Merkmalen, wobei "Testlauf" gleichbedeutend mit der Prozedur des "Testens" im oben erläuterten Sinne zu verstehen ist:
- – Zu Beginn des Testlaufs des Diagnosesystems wird auf Basis einer getroffenen Betriebsmodusauswahl automatisch bestimmt, welches von mehreren Phantomen für den Testlauf zu verwenden ist, wobei die Betriebsmodusauswahl entweder unmittelbar durch den Nutzer des Diagnosesystems oder automatisiert auf Grundlage existierender Parametereinstellungen des Diagnosesystems erfolgt,
- – das zu verwendende Phantom wird automatisch aus dem bevorzugt in die Patientenliege integrierten Speicherbehälter entnommen und an für die Durchführung des Testlaufs geeigneter Stelle an der Patientenliege, insbesondere an einer Stirnseite des Liegenbretts, befestigt,
- – der Testlauf wird durchgeführt, wobei durch das Diagnosegerät Merkmale des Phantoms erfasst werden,
- – das Phantom wird nach beendetem Testlauf automatisch zurück in den Speicherbehälter transportiert.
- At the beginning of the test run of the diagnostic system, based on a selected operating mode selection, it is automatically determined which of several phantoms to use for the test run, the operating mode selection being either directly by the user of the diagnostic system or automated based on existing parameter settings of the diagnostic system,
- The phantom to be used is automatically removed from the storage container, which is preferably integrated in the patient bed, and attached to a suitable place for carrying out the test run on the patient bed, in particular on an end face of the bed board.
- The test run is carried out, whereby features of the phantom are detected by the diagnostic device,
- - the phantom is automatically transported back to the storage container after the test run has ended.
Der Testlauf wird als sogenannter "Quality-Checkup" beispielsweise nach dem Einschalten des Diagnosegerätes durchgeführt. Der gesamte Testlauf, auch als Service-Programm bezeichnet, läuft komplett automatisiert ab, so dass die Benutzerfreundlichkeit sowie Prozesssicherheit maximal ist. The test run is performed as a so-called "quality checkup", for example after switching on the diagnostic device. The entire test run, also referred to as a service program, runs completely automatically, so that the user-friendliness and process reliability are maximum.
