(Prior Art) An example of fluoroscopic diagnosis in a conventional example of this type of X-ray diagnostic apparatus will be described. That is, the operator may have to issue a fluoroscopic command to the patient placed on the bed while performing a hand fixation motion or the like for palpation. In this case, a manual or foot-operated fluoroscopic command switch may be installed near the bed for the operator to issue commands, or another operator may be required to provide fluoroscopic commands to the operating section of the control system. It is common practice to put For example, when performing gastrointestinal system diagnosis on children, especially infants, the surgeon is preoccupied with fixing the patient, changing the position, etc., and the operation of the equipment, that is, the operation of fluoroscopic commands, is slow. It tends to become. As a result, patients sometimes missed the timing to issue a fluoroscopy command or forgot to release a fluoroscopy switch, making it impossible to perform a reliable diagnosis even if they required more personnel, and causing an increase in radiation exposure. .

(Problems to be Solved by the Invention) As described above, with conventional X-ray diagnostic equipment, the operator cannot concentrate on fluoroscopic operations and display observation, and despite the trouble, reliable fluoroscopy can be achieved. However, there were problems in that it was difficult to carry out and resulted in an increase in the amount of radiation exposure.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an X-ray diagnostic device that allows the operator to concentrate on fluoroscopic operations and display observation, allows simple and reliable fluoroscopy, and eliminates the problem of radiation exposure. .

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above problems and achieve the objects, the present invention is configured as follows. That is, the present invention provides a bed section on which a subject is placed, a control system that gives an X-ray irradiation instruction to an X-ray source to irradiate the subject with X-rays, and a control system that provides an X-ray irradiation instruction to the an imaging system that is provided facing each other via a bed section and that converts transmitted X-rays irradiated from the X-ray source and transmitted through the subject into electrical signals to obtain an X-ray fluoroscopic image; It has a display system that displays the X-ray fluoroscopic image, and a command stage that gives an X-ray exposure command to the control system, and this command means is worn by the operator and transmits electromagnetic waves including sound waves or light. a carbon wave generator that emits waves; a receiver that receives the electromagnetic waves and generates a received signal when the positional relationship between the wave transmitter and the wave transmitter becomes a predetermined position; and a receiver that receives the electromagnetic waves from the receiver. The configuration includes determination means for providing an X-ray exposure command signal to the control system based on the signal.

(Operation) According to such a configuration, fluoroscopy is performed only when the operator is ready to perform fluoroscopic diagnosis, and the fluoroscopic image can be observed.

(Embodiment) An embodiment of the X-ray diagnostic apparatus according to the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the configuration of this embodiment, FIG. 2 is a system configuration diagram of the same embodiment, and FIG. 3 is a perspective view showing the configuration of the ultrasonic transmitter in FIG. 1.

As shown in FIGS. 1 and 2, a bed section 1 on which a patient P is placed, an X-ray source 2, a spot shot photographing device 3a using X-ray film, an image intensifier 3b, and an optical system 3c. , an imaging system 3 having a TV camera 3d, an operation unit (console) 4a as a control system 4, and a high voltage generation circuit 4b.
and a display system 5 having a TV monitor 5a,
A fluoroscopic image of the patient P placed on the bed section 1 can be displayed on a display system 5, and X-ray film photography can also be performed using a spot shot photographing device 3a. Here, the bed section 1, the X-ray source 2, and the imaging system 3 constitute a fluoroscopic bed apparatus, and the operating section (console) 4a is a proximity operation console that can be moved close to the fluoroscopic bed apparatus.

Further, a battery-operated ultrasonic transmitter 5 is detachably attached to the head of the surgeon S. This ultrasonic transmitter 6 includes a head band 6 as shown in FIG.
a, a transmitting section 6b, and a movable fixture 6c, and the transmitting section 6b is configured to be tiltable in the direction of the arrow shown in the figure so that the transmitted ultrasonic waves can be transmitted in a desired direction. According to this configuration, it is possible to compensate for the height of the surgeon S, and when he or she directs his/her line of sight in a predetermined direction (the direction of the display surface of the TV monitor 5a), the ultrasound is transmitted in approximately the same direction as the line of sight. be able to.

Further, the ultrasonic receiver 6 is disposed with its wave receiving direction set approximately perpendicular to the display surface of the display system 5. A transmitter/receiver 9 that detects whether the surgeon S is on the bed section 1 or the operating section 4a by transmitting and receiving ultrasonic waves is installed, for example, in the operating section 4a.
These ultrasonic receiver 7 and transmitter/receiver 9 output a signal when a receiving operation is performed, and the signal is input to the determination circuit 8, which issues a fluoroscopic X-ray irradiation command to the control system 4. Here, the condition for giving the fluoroscopic X-ray irradiation command in the determination circuit 8 is when both the ultrasonic receiver 7 and the transceiver 9 output signals. Also, with this condition established, lamp 1
0 is now displayed. Note that the fluoroscopic X-ray irradiation command is output after a predetermined period of time has elapsed after the above conditions are satisfied and the lamp 10 is turned on. The determination circuit 8 is incorporated into the control system 4.

Next, the operation of this embodiment configured as described above will be explained.

That is, assume that the surgeon S is wearing the ultrasound transmitter 6 and palpating the patient P. At this time,
Due to the fact that the surgeon S's line of sight is directed towards the patient P, etc.
I am not looking at the TV monitor 5a,
The transmitted ultrasound from the ultrasound transmitter 6 is not received by the ultrasound receiver 7, and therefore the ultrasound receiver 7 does not output a signal. Therefore, the transmitter/receiver 9 is connected to the operator S.
Even if the presence of the device is detected near the bed portion 1 or the operation portion 4a, the determination circuit 8 does not operate, and no fluoroscopy is performed.

Next, when the operator S wishes to perform fluoroscopy during palpation and turns his/her line of sight to the TV monitor 5a, the transmitted ultrasound from the ultrasound transmitter 6 is received by the ultrasound receiver 7, and the ultrasound receiver 7 supplies a signal to the determination circuit 8. Here, if the transmitter/receiver 9 detects the presence of the operator S near the bed section 1 or the operating section 4a, the determination circuit 8 operates to light the lamp 10, and then sends the control system 4 to transmit the fluoroscopic X-ray. Give irradiation command. Thereby, the fluoroscopic X-rays from the X-ray source 1 pass through the patient P, reach the imaging system 3, obtain a fluoroscopic image, and display it on the TV monitor 5a. Of course, since the surgeon S is looking at the TV monitor 5a, he can observe the transparent image.

According to this embodiment as described above, the following effects are achieved.

According to this embodiment, the operator S uses the TV monitor 5a.
When you look at the object and are in a predetermined area, the see-through operation is activated and you can observe the see-through image. This allows operator S to concentrate on palpation,
Further, since the fluoroscopy operation is performed only when image observation is necessary, the patient P and the operator S can be prevented from being exposed to unnecessary radiation due to forgetting to turn off the switch.

According to this embodiment, after the perspective condition is satisfied,
The operator S is informed that the condition has been met by lighting the lamp 10, and then the fluoroscopy operation starts after some time, so the operator S can grasp the timing of X-ray exposure and take actions to avoid exposure. .

In this embodiment, the fluoroscopy command is executed not by hand or foot movements of the operator S, but by directing the line of sight and being within a predetermined area.
It is practical because it is easy to operate, and the ultrasonic device and the like are small and inexpensive.

The present invention can be modified and implemented as follows. In other words, the installation position of the ultrasonic device is not limited to the installation location in the above embodiment, but can be installed at any suitable position where line of sight detection and position detection can be performed. Instead, a wireless device such as an optical transmitter/receiver, a radio wave transmitter/receiver, an infrared transmitter/receiver, or the like may be used to transmit information from the operator to the monitor side or to detect the position.

In addition, various modifications can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As described above, the present invention is equipped with a fluoroscopic command means that detects that the operator is ready to perform fluoroscopic diagnosis and issues a fluoroscopic X-ray irradiation command to the control system. Fluoroscopic diagnosis can be performed as soon as the patient is ready to perform fluoroscopic diagnosis, and the fluoroscopic image can be observed, allowing the operator to concentrate on fluoroscopic operations and display observation, making it easier and more reliable. Therefore, it is possible to provide an X-ray diagnostic apparatus that can solve the problem of radiation exposure.
