  When performing a procedure using a fluoroscopic imaging device, a person other than the operator operates the lighting device to make the lighting device darker or darker, so there is a gap between when the operator wants to change the illumination and when the illumination actually changes. . In addition, when the surgeon gives an instruction to change the illumination, there is a problem that the work is not delayed and the work cannot be smoothly performed.

  In order to solve the above problems, the present invention provides an X-ray irradiation means for irradiating a subject with X-rays, an X-ray detection means for detecting X-rays transmitted through the subject, and the X-ray detection means. In an X-ray fluoroscopic apparatus comprising an image display unit that displays an image captured by the above, an illuminating device that illuminates the examination room, an illumination control device that controls the brightness of the illuminating device, and an operator's head A signal transmission device that generates a signal for illumination, and a signal reception device that receives a signal for illumination installed in the central portion of the image display unit, and the operator views the central portion of the image display unit. When the signal receiving device receives the signal from the signal transmitting device and darkens the lighting device, the operator is not looking at the image display unit, and receives the signal from the signal transmitting device. If the device does not receive Characterized by comprising a lighting control device for controlling the illumination device to the bright state.

  In addition, the present invention provides a brightness control device in which a sensor for detecting the brightness of a room is installed in the image display unit and the brightness of a fluoroscopic image display monitor installed in the image display unit is adjusted using a signal of the sensor. It is provided with.

  The surgeon can control the brightness of the lighting device by controlling the direction of the signal of the transmitting device in conjunction with the movement of the head, and further control the brightness of the monitor in conjunction with the light and dark control. Since it can be performed, the environment of the technique in accordance with the operator's request can be realized.

  According to the present invention, the surgeon can perform brightness control of the illumination device and brightness control of the monitor of the image display unit without bothering one by one, so that a smooth and comfortable procedure can be efficiently performed.

It is a block diagram which shows the outline | summary of the X-ray fluoroscope of the Example by this invention. It is a side view which shows the relationship between the operator of the X-ray fluoroscopic apparatus of the Example by this invention, and an image display part.

  FIG. 1 shows a schematic configuration of the X-ray fluoroscopic apparatus of the present invention. An X-ray fluoroscopic apparatus installed in an examination room 20 provided with an illuminating device 12 includes an X-ray tube 1 and an X-ray held opposite to both ends of a C-type arm 3 supported from the ceiling by an arm support 4. It comprises a detector 2, an examination table 6 on which a subject 9 held on a holding table 19 lies, an operation unit 7 for operating the entire X-ray fluoroscopic apparatus, and an image display unit 8. The subject 9 lies down on the examination table 6, and the operator 10 operates the operation unit 7 to perform fluoroscopy and imaging, and the fluoroscopic image is displayed on the monitor 5 of the image display unit 8. It should be noted that at least two monitors 5 are required with a configuration of a monitor that reflects an image seen through during the procedure and a monitor that refers to an image taken before that. Further, as an option, a monitor for displaying a 3D image or displaying an image (CT image or the like) of another system is added. In this embodiment, a case where four monitors are installed is shown.

  Further, the operator 10 wears goggles 11 for protection against X-ray exposure, and a signal transmission device 13 is attached to the goggles 11, and the signal receiving device 14 and the image display portion 8 are further provided in the image display portion 8. A sensor 15 that detects light and darkness in the vicinity is installed. In addition, a control device 18 that controls the brightness of the illumination device 12 and the brightness of the monitor 5 is installed.

  FIG. 2 is a side view showing the relationship between the operator 10 and the image display unit 8 of the X-ray fluoroscopic apparatus according to the embodiment of the present invention. As shown in FIG. 2, when the operator 10 looks at the center of the image display unit 8 in a natural posture, the signal emitted from the signal transmission device 13 attached to the goggles 11 is input to the signal reception device 14. The direction of the transmission device 13 is adjusted in advance. As an example of the present invention, an infrared light emitting element is used for the signal transmission device 13 and an infrared sensor is used for the signal reception device 14. When the operator 10 views the image display unit 8 and the signal of the signal transmission device 13 is input to the signal reception device 14, the illumination device 12 is controlled to be in a dark state by the control device 18 connected to the power source 21 (FIG. 1). The

  When the signal from the signal transmission device 13 is not input to the signal receiving device 14 by looking at the hand to perform the procedure, the lighting device 12 is controlled to the bright state by the control device 18. Accordingly, the room illumination becomes bright when looking at the hand, and the room illumination becomes dark when looking at the image display unit 8.

  Incidentally, it is required to adjust the brightness of the monitor 5 in order to make it easier to see the image displayed on the monitor 5 installed in the image display unit 8. When the operator 10 is looking at the image display unit 8, the illumination device 12 is controlled to be in a dark state, and the brightness near the image display unit 8 is detected by the sensor 15 installed in the image display unit 8. Using the signal from the sensor 15, the control device 18 adjusts the fluoroscopic image display monitor 5 installed in the image display unit 8 to an optimum luminance. For example, the brightness of the monitor 5 is adjusted according to an adjustment table (not shown) of the brightness around the monitor that is considered easy to see and the brightness of the monitor screen.

  In the embodiment according to the present invention, an infrared light emitting element is used for the signal transmitting device 13 and an infrared sensor is used for the signal receiving device 14, but an optical sensor using visible light may be used, and the present invention is not limited to these. Absent. Further, the attachment of the signal transmission device 13 is not limited to the goggles 11, and may be attached to, for example, a hat worn during the procedure.

  1 and 2 denote the same items.
