Description
Die Erfindung betrifft ein Verfahren zur Navigation einer Röntgendiagnostikeinrichtung und eine Vorrichtung zur Durchführung des Verfahrens.The The invention relates to a method for navigating an X-ray diagnostic device and a device for implementation of the procedure.
Aus der deutschen Patentschrift DE282233 ist ein Verfahren zur Darstellung und Dokumentation von Aufnahmegeometrien für Röntgenuntersuchungen bekannt, bei dem von dem die Röntgenaufnahmen veranlassenden Arzt die Richtung des Zentralstrahls mit Hilfe von Fähnchen an einer Puppe markiert werden. Die mit den Fähnchen versehene Puppe dient dem Einrichter der Röntgendiagnostikeinrichtung als Vorlage für die Einstellung der Aufnahmegeometrie.Out German Patent DE282233 is a method of representation and documentation of acquisition geometries for X-ray examinations, at which the x-rays inducing doctor the direction of the central ray with the help of flag to be marked on a doll. The doll provided with the flags serves the installer of the X-ray diagnostic device as a template for the setting of the recording geometry.
Aus der PCT-Anmeldung WO0150959A1 ist eine Röntgendiagnostikeinrichtung mit einem motorisch verstellbaren C-Bogen bekannt, bei dem die Bedienperson der Röntgendiagnostikeinrichtung die Bewegung des C-Bogens mit Hilfe eines Joysticks steuert. Bei einem Einsatz in der Chirurgie muß sich der Joystick im sterilen Bereich befinden. Die Navigation des C-Bogens mit Hilfe eines Joysticks setzt seitens der Bedienperson ein Vorstellungsvermögen von der Kinematik des C-Bogens voraus. Die Verstellung des C-Bogens mit Hilfe eines Joysticks erlaubt es beispielsweise, daß der Operateur selbst die Bedienung des C-Bogens vornimmt. Dieser kann den C-Bogen nur dann verantwortungsvoll führen, wenn er ein Vorstellungsvermögen von der Kinematik des C-Bogens besitzt. Dies ist insbesondere dann der Fall, wenn eine Verstellung des Zentralstrahls um etwa 90 Grad gegenüber der aktuellen Stellung erreicht werden soll.Out PCT application WO0150959A1 is an X-ray diagnostic device known with a motor-adjustable C-arm, in which the operator the X-ray diagnostic device controls the movement of the C-arm with the aid of a joystick. at For use in surgery, the joystick must be sterile Area are located. The navigation of the C-arm with the help of a joystick sets the operator an imagination of preceded by the kinematics of the C-arm. The adjustment of the C-arm with the help of a joystick, for example, it allows the surgeon even the operation of the C-arm makes. This can be the C-bow only then lead responsibly, if he has an imagination from the kinematics of the C-arm. This is especially true the case when an adjustment of the central ray by about 90 degrees across from the current position is to be achieved.
Aus dem Dokument DE69231553T2 ist eine drahtlose Fernbedienung für eine Röntgendiagnostikeinrichtung bekannt.Out Document DE69231553T2 is a wireless remote control for an X-ray diagnostic device known.
Das Dokument DE69503814T2 betrifft einen Markierungsstift für einen Chirurgen, wobei an dem Markierungsstift videoerkennbare Marken aufgebracht sind, die eine Ortung des Markierungsstiftes mit Hilfe eines Videosystems ermöglichen.The Document DE69503814T2 relates to a marking pen for a Surgeons, where on the marker pen video detectable brands are applied, a location of the marker pen with the help of a video system.
In einer Operationssituation mit einer chirurgischen Röntgendiagnostikeinrichtung ist es für den Patienten, den Operateur und den Kostenträger vorteilhaft, wenn eine vom Operateur gewünschte Aufnahmegeometrie schnell und zuverlässig eingestellt wird, ohne daß der Operateur seine Arbeitsposition verändern muß. Dabei soll die Strahlenbelastung für Arzt und Patient nicht unnötig erhöht werden.In an operative situation with a surgical X-ray diagnostic device is it for the patient, the surgeon and the payer advantageous if a desired by the surgeon Recording geometry is set quickly and reliably, without that the Surgeon must change his working position. It should the radiation exposure for doctor and patient not unnecessary elevated become.
Der Erfindung liegt daher die Aufgabe zu Grunde, ein Verfahren zur Navigation deiner Röntgendiagnostikeinrichtung und eine Vorrichtung für das Verfahren zu schaffen, bei der ein Operateur ohne seine Arbeitsposition verändern zu müssen, den Wunsch nach einer bestimmten Aufnahmegeometrie Kind tut und die Röntgendiagnostikeinrichtung die Erkennung des Wunsches, nachfolgend "Bedienerwunsch" genannt, und die Umsetzung des Bedienerwunsches automatisch vornimmt.Of the The invention is therefore based on the object, a method for navigation your X-ray diagnostic facility and a device for the To provide a procedure in which an operator without his working position change to have the Desire for a particular recording geometry child does and who X-ray diagnostic device the Recognition of the desire, hereinafter referred to as "operator request", and the implementation of the user request automatically performs.
Die Aufgabe der Erfindung wird dadurch gelöst, daß der Operateur – nachfolgend auch als "Bediener" bezeichnet – mit einem röntgenpositiven Zeiger – nachfolgend als "Röntgenzeiger" bezeichnet – im Operationsfeld auf den Punkt des Interesses (Point of Interest "POI") zeigt und durch die Richtung des Zeigers die gewünschte Richtung des Zentralstrahls der Röntgendiagnostikeinrichtung festlegt. Der Bediener veranlaßt weiter die Röntgendiagnostikeinrichtung, eine Röntgenaufnahme zu machen und mittels eines geeigneten Bildbearbeitungsprogrammes die Lage des POI und die Richtung des Zentralstrahls im Koordinatensystem des Röntgenstrahlenenpfängers zu bestimmen. Der Steuerrechner der Röntgendiagnostikeinrichtung errechnet für jede Verstellachse des C-Bogens den Verstellweg beziehungsweise den Verstellwinkel und führt dies Verstellung auf einen bestimmten Steuerbefehl hin selbsttätig aus.The The object of the invention is achieved in that the surgeon - below also called "operator" - with a radiopaque Pointer - below referred to as "X-ray pointer" - in the surgical field to the point of interest (Point of Interest "POI") shows and by the direction of the pointer the desired direction of the central beam the X-ray diagnostic device sets. The operator initiates continue the X-ray diagnostic device, an x-ray and by means of a suitable image editing program the position of the POI and the direction of the central ray in the coordinate system of the X-ray receiver determine. The control computer of the X-ray diagnostic facility calculated for each adjustment axis of the C-arm the adjustment or the adjustment and leads Adjustment to a specific control command automatically off.
Die nächste Röntgenaufnahme, bei der sich der Röntgenzeiger nicht mehr im Operationsfeld befindet, wird mit der vom Operateur gewünschten Aufnahmegeometrie aufgenommen.The next X-ray, at the X-ray pointer no longer in the surgical field, is with the surgeon desired Recording geometry recorded.
Die Erfindung wird nachstehend an Hand der Abbildungen näher erläutert.The Invention will be explained below with reference to the drawings.
