(Example) Hereinafter, an example of a fruitful color of an X-ray diagnostic apparatus according to the present invention will be described 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, there is a bed section 1 on which the patient P is placed, an X-ray source 2, a spot shot @ shadow device 3a using X-ray film, and an image intensifier 3.
b, an optical system 3c, an imaging system 3 that holds a TV camera 3d;
The control system 4 includes an operation unit (console>4a and 1JAt
It is equipped with a pressure generating circuit 4b and a display system 5 having a TV monitor 5a, and can display a fluoroscopic image of the patient P placed on the bed section 1 on the display system 5, and a spot shot photographing device 3a.
X-ray film imaging can also be performed.

Here, the bed section 1. X-ray source 2. The imaging system 3 constitutes 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. As shown in FIG. 3, this ultrasonic transmitter 6 includes a headband 6a.

The transmitter 6b and the movable mounting are composed of a fixture 6C, and the transmitter 6b is moved in the direction of the arrow shown in the figure so that the transmitted ultrasonic waves can be transmitted in a desired direction.
is configured to be tiltable. According to this coincidence, the caster S
It is possible to compensate for the height of the
If the line 71 is directed in the direction of the display surface of the monitor 5a, ultrasonic waves can be transmitted in substantially the same direction as the line of sight.

Further, the ultrasonic receiver 6 is disposed with its wave receiving direction set approximately perpendicular to the display surface of the display system 5. Then, a transmitter/receiver 9 for detecting that the surgeon S is on the bed section 1 or the operating section 4a by transmitting and receiving ultrasonic waves is connected to the operating section 4a, for example.
The ultrasonic receiver 7 and transmitter/receiver 9 output a signal when a reception operation is performed, and the determination circuit 8
The control system 4 receives a fluoroscopic X-ray irradiation command. Here, is the transparency in the determination circuit 8?
The condition for giving the Jf X-ray irradiation command is when both the ultrasonic receiver 7 and the transceiver 9 output signals.

Further, when this condition is met, the lamp 10 is 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.

In other words, the surgeon S attaches the ultrasound transmitter 6 to the patient P.
Suppose that you are palpating the At this time, the operator S's line of sight is directed towards the patient P and is not looking at the TV monitor 5a, and the transmitted ultrasound from the ultrasound transmitter 6 is not received by the ultrasound receiver 7. Therefore, the ultrasonic receiver 7 does not output a signal. Therefore, even if the transmitter/receiver 9 detects the presence of the surgeon S near the bed section 1 or the operating section 4a, the determination circuit 8 does not operate and fluoroscopy is not performed.

Next, operator S wishes to perform fluoroscopy during palpation, and
When looking at the monitor 5a, the transmitted ultrasound from the ultrasound transmitter 6 is received by the ultrasound receiver 7.
gives 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. As a result, the fluoroscopic X-rays from X1llil pass through the patient P and reach the image carrier system 3 to obtain a fluoroscopic image, which is displayed on the TV monitor 5a. Of course, since the surgeon S is directing his/her line of sight to the TV monitor 5a, he/she can observe the fluoroscopic image.

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

According to the present embodiment, when the surgeon S looks toward the TV monitor 5a and is present in a predetermined area, the fluoroscopy operation is activated, and the fluoroscopy operation is activated. 14 images can be observed. This allows the operator S to concentrate on palpation, and since the fluoroscopy operation is performed only when necessary for image observation, the patient P and the operator S are prevented from unnecessary exposure to radiation due to forgetting to turn off the switch, etc. be able to.

■ According to this embodiment, after the fluoroscopy conditions are established, the operator
The establishment of the condition is notified by lighting the lamp 10, and then the fluoroscopy operation starts after a while, so the operator S can grasp the timing of X-ray irradiation and take actions to avoid sunlight.

■ Fluoroscopic commands in this example are executed by directing the line of sight and being in a predetermined area, rather than by hand or foot movements of the surgical BS, so the operation is easy, and the ultrasonic device etc. It is also practical because it is 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 of the sonic device, 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.

The invention can be modified in various ways without departing from the essence of the invention.

[Effects of the Invention] As described above, the present invention is configured to include 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. Therefore, only when the surgeon is ready to perform a fluoroscopic diagnosis, a fluoroscopic image is obtained.
