Abstract

The appts. has an X-ray source (2) which is operated periodically for intermittent irradiation of the patient. A direct visual image is obtained on a monitor (7) by using an X-ray image amplifier (3) and a video camera (5). The latter is coupled to the monitor via an electronic image storage device (6), so that the preceding image is viewed during the intervals between successive irradiations. The spacing between the irradiations is adjusted via a setting control (12) coupled to the periodic control (9) for the X-ray source (2), with a mode selection switch (11) allowing the stationary image mode to be selected. Pref. a further setting control (13) is coupled to a control logic (8) for adjusting the X-ray dosage.

Description

Röntgendiagnostikanlage für intermittierenden Durch-X-ray diagnostic system for intermittent

leuchtungsbetrieb Die Erfindung betrifft eine Röntgendiagnostikanlage mit einer Bildverstärker-Fernseh-Kette und Mitteln zum periodischen Einsc-halten der Röntgenröhre für intermittierende Durchleuchtung, bei der ein-elektronischer Biidspeicher vorhanden ist, der das jeweilige durch Strahlung erzeugte Röntgenbild speichert und dem Sichtgerät der Bildverstärker-Fernseh-Kette zuführt, bis der nächste Röntgenstrahlungsimpuis auftritt.lighting operation The invention relates to an X-ray diagnostic system with an image intensifier television chain and means for periodic inclusion the X-ray tube for intermittent fluoroscopy, with the one-electronic Image storage is available, which contains the respective X-ray image generated by radiation stores and feeds the display unit of the image intensifier television chain until the next one X-ray pulse occurs.

Eine Röntgendiagnostikanlage dieser Art ist in der Zeitschrift "Electromedica", 1975, auf den Seiten 148 bis 157, beschrieben. Bei dieser Röntgendiagnostikanlage wird nicht mit fortlaufender Strahlung gearbei--tet, bei der in jedem Fernsehhalbbild eine neue Bildinformation enthalten ist, sondern die Strahlung wird nur in bestimmten Zeitabständen, z.B. zu jedem fünften Bild, eingeschaltet. Das durch sdie Strahlung erzeugte Bild wird gespeichert und auf dem Sichtgerät wiedergegeben, bis erneut ein Röntgenstrahlungsimpuls auftritt.An X-ray diagnostic system of this type is in the magazine "Electromedica", 1975, on pages 148-157. With this X-ray diagnostic system continuous radiation is not used in every television field a new image information is contained, but the radiation is only in certain Time intervals, e.g. for every fifth picture, switched on. That through the radiation generated image is saved and played back on the display device until again an X-ray pulse occurs.

Der Erfindung liegt die Aufgabe zugrunde, eine Röntgendiagnostikanlage der eingangs genannten Art so auszubilden, daß eine Einstellung zwischen Standbildbetrieb und intermittierender Durchleuchtung mit unterschiedlichen Abständen der Röntgenstrahlungsimpulse möglich ist.The invention is based on the object of an X-ray diagnostic system of the type mentioned in such a way that a setting between still image mode and intermittent fluoroscopy with different X-ray pulse spacing is possible.

Diese Aufgabe ist demgemäß dadurch gelöst, daß Einstellmittel für den Abstand der Röntgenstrahlungsimpulse vorgesehen sind und daß ein Betriebsschalter vorhanden ist, durch den auf Standbetrieb umschaltbar ist.This object is accordingly achieved in that adjusting means for the spacing of the X-ray pulses are provided and that an operating switch is available, which can be switched to stand-by mode.

Bei der erfindungsgemäßen Röntgendiagnostikanlage ist durch einen Betriebsschalter die Betriebsart, also laufende Durchleuchtung oder Standbildbetrieb, zu wählen.In the X-ray diagnostic system according to the invention is by a Operating switch the operating mode, i.e. ongoing fluoroscopy or freeze frame operation, to choose.

Wird laufende Durchleuchtung gewählt,so ist über Einstellmittel der Abstand der Röntgenstrahlungsimpulse bis zum Durchlaufbetrieb einstellbar.If ongoing fluoroscopy is selected, the setting means is The distance between the X-ray pulses can be set up to continuous operation.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is illustrated below with reference to one in the drawing Embodiment explained in more detail.

in.der Zeichnung ist ein Patient 1 dargestellt, der von einer Röntgenröhre 2 durchstrahlt wird. Die Durchleuchtungsbilder werden von einem Röntgenbildverstärker 3 verstärkt und über eine eInstellbare Irisblende 4 einer Fernsehkamera 5 zugeführt, die an einem Video speicher 6 angeschlossen ist. Der Videospeicher 6 steuert ein Sichtgerät 7 und ist seinerseits an einer Steuerlogik 8 angeschlossen, die auch die Fernsehkamera 5 und einen Röntgengenerator 9 für die Röntgenröhre 2 steuert. Eine Einstellvorrichtung 10 besitzt einen Betriebsschalter 11 sowie Einstellmittel 12 und 13.in.der drawing a patient 1 is shown by an X-ray tube 2 is irradiated. The fluoroscopic images are taken from an X-ray image intensifier 3 amplified and fed to a television camera 5 via an adjustable iris diaphragm 4, which is connected to a video memory 6. The video memory 6 controls Display device 7 and is in turn connected to a control logic 8, which also the television camera 5 and an X-ray generator 9 for the X-ray tube 2 controls. A setting device 10 has an operating switch 11 and setting means 12 and 13.

Die Steuerlogik 8 beeinflußt den Röntgengenerator 9 in der Weise, daß zur Durchleuchtung des Patienten 1 Röntgenstrahlungsimpulse ausgesandt werden, daß also die Röntgenröhre 2 periodisch eingeschaltet wird. Sie steuert die Abtastung des Target der Fernsehkamera 5 so, daß dieses zu jedem Röntgenstrahlungsimpuls einmal abgetastet wird und bewirkt die Einspeicherung des abgetasteten Bildes in den Video speicher 6. Der Abstand der Röntgenstrahlungsimpulse ist durch die Einstellmittel 12 einstellbar. In der Zeit, in der kein. unmittelbar durch Strahlung erzeugtes Bild vorliegt, wird das jeweils letzte Bild aus dem Videospeicher 6 auf dem Sichtgerät 7 wiedergegeben. über die Einstellmittel 12 ist der Abstand der Röntgenstrahlungsimpulse den Wünschen des Benutzers entsprechend optimal bis zum Durchlaufbetrieb einstellbar, bei dem Dauerstrahlung vorliegt.The control logic 8 influences the X-ray generator 9 in such a way that that 1 x-ray pulses are sent out to x-ray the patient, so that the X-ray tube 2 is switched on periodically. It controls the scanning of the target of the television camera 5 so that this once for each X-ray pulse is scanned and causes the scanned image to be stored in the video memory 6. The distance the x-ray pulse is through the Setting means 12 adjustable. In the time when no. directly from radiation generated image is present, the last image from the video memory 6 is on the display device 7 reproduced. The distance between the X-ray pulses is determined via the setting means 12 optimally adjustable according to the wishes of the user up to continuous operation, in which there is continuous radiation.

über den Betriebsschalter 11 ist auf Standbildbetrieb umschaltbar, bei dem die Einstellmittel 12 abgeschaltet sind und das jeweils zuletzt im Video speicher 6 gespeicherte Bild als Standbild auf dem Sichtgerät 7 wiedergegeben wird. Die Einstellmittel 13 erlauben die Einstellung der Röntgenröhrenspannung und gegebenenfalls der Dosisleistungswerte für den Fall, daß eine Dosisleistungsregeleinrichtung vorgesehen ist.The operating switch 11 can be switched to freeze mode, in which the setting means 12 are switched off and that last in each case in the video memory 6 stored image is displayed as a still image on the display device 7. The setting means 13 allow the setting of the X-ray tube voltage and, if necessary the dose rate values in the event that a dose rate control device is provided is.
