Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray fluoroscopy for radiating X-rays to a subject on a fluoroscopic imaging table in response to a control command from a remote operation console and capturing a transmitted X-ray image of the subject on a film. Regarding the imaging device, in particular, the operator can transfer the identification information of the subject and other information to the film by operating on the remote control table without going to the photography room one by one, and input the identification information of the subject. It is also possible to display the identification information directly on the film by connecting to a computer device that outputs information to another device by communication, and display, store and output other information on the computer device. The present invention relates to a fluoroscopic imaging apparatus.

[0002]

2. Description of the Related Art Generally, when a diagnostic region of a subject is radiographed by an X-ray fluoroscopic imaging apparatus, identification information such as the name, age and sex of the subject is imprinted on a part of the film. , After that, it is possible to check and sort out the subjects of which the film has been shot.

For this reason, conventionally, as shown in FIG. 3, a name print section 2 is provided at a predetermined position of a quick-shooting device 1 for sequentially sending a film to a photographing position of a transmission X-ray image of a subject, and this name print is carried out. The identification card 3 in which the date of photography, the name, age, etc. of the subject, as shown in FIG. 4, is inserted into the insertion hole of the portion 2 in the direction of arrow A. Then, when an X-ray image of the subject is taken, as shown in FIG. 5, the light source 4 provided in the name print unit 2 is turned on and the identification information of the identification card 3 is narrowed down by the optical system 5. By forming this optical image on a part of the film 6, as shown in FIG. 6, the identification information ID of the subject is printed on one corner of the film 6.

[0004] Further, regarding the photographing conditions such as X-ray tube voltage and tube current and the photographing information such as the number of photographed images at the time of the examination of the subject, a doctor or an inspection technician who is in charge of the examination makes a chart or irradiation of the subject. I was manually writing on recording paper such as recordings. Alternatively, an output device such as a photographing condition printer prints on a recording sheet and the recording sheet is attached to the chart of the subject.

[0005]

However, in imprinting the identification information of the subject in such a conventional X-ray fluoroscopic imaging apparatus, the name printer section 2 is used as the quick-copying apparatus 1.
Since it is built in, the operator such as a doctor goes to the radiography room from the remote operation console in the operation room every time the photographing of one subject is finished, and the identification card inserted in the name print section 2 is inserted. It was necessary to pull out 3 and insert a new identification card 3 on which the identification information of the next subject was written, and return to the operation room again. Then, the replacement work of the identification card 3 has to be repeated for the number of examinees to be imaged (for example, about 15 to 20 persons a day). Therefore, the operability of the X-ray fluoroscopic imaging apparatus deteriorates, the imaging efficiency also decreases, and the operator's fatigue increases.

Further, in recording the photographing information, since an operator such as a doctor manually writes in a medical record or an irradiation record, the writing is complicated and a writing error may occur. Shooting conditions Even when printed out by a printer, the recording sheet must be attached to the chart of the subject after that, which is also complicated and the attachment of the recording sheet makes the chart bulky and inconvenient to organize. It was a thing. Furthermore, since the patient's medical records and radiation records are stored as they are in the hospital where they were inspected,
The history of X-ray exposure for an individual subject was not recorded as a total, and it was almost impossible to control the exposure for each individual subject.

Therefore, the present invention solves such a problem and allows the identification information of the examinee and other information to be transferred onto a film by an operation on a remote control table, and the examination can be carried out in a hospital. It is an object of the present invention to provide an X-ray fluoroscopic imaging apparatus capable of improving the operability of an operator by connecting to a computer apparatus or the like for inputting identification information of an operator and managing necessary information for each patient in a hospital. .

[0008]

In order to achieve the above object, an X-ray fluoroscopic imaging apparatus according to the present invention emits X-rays to a subject on the fluoroscopic imaging table according to a control command from a remote operation console,
In the X-ray fluoroscopic imaging apparatus for photographing a transmission X-ray image of the subject on a film, the remote operation console has information reading means for reading identification information from a chart or the like of the subject, and identification information of the subject. An information input / output device that inputs, stores, and outputs information of a computer device that manages information, a means for transmitting identification information from the information input / output device by communication, and a means for switching received information from the information reading means. And a display control means for storing and controlling the display of the read identification information, and displaying the information from the display control means on the film transporting device section of the fluoroscopic imaging table. An information recording means to be imprinted on a part of the remote control console is provided, and the control device of the remote operation console and individual control devices of the fluoroscopic imaging stand and peripheral devices for controlling the operation of X-ray generation are mutually connected by a communication line. It has a step and transmits control information of the remote operation console, the fluoroscopic imaging stand and the X-ray generator, and information such as photographing conditions, the number of times of photographing and the number of films to the information input / output means such as a computer. .

Further, the remote operation console is provided with a confirmation display means for displaying a photographing state or for displaying on the monitor the identification information etc. imprinted by the information recording means to improve the operability. .

[0010]

In the X-ray fluoroscopic imaging apparatus thus constructed, the identification information is read from the patient's chart or the like by using the information reading means provided on the remote control console, or the information input / output apparatus is used. The identification information is switched and read, the read identification information is stored in the display control means and the display is controlled, and the information from the display control means is displayed by the information recording means provided in the film transport device section of the fluoroscopic imaging table. At the same time, it is imprinted on a part of the film, and imaging information of the subject at the time of examination is transmitted to the information input / output device via communication.

Further, since the control device of the remote operation console and the individual control devices of the fluoroscopic imaging stand and the peripheral device for controlling the operation of generating X-rays are connected to each other by a communication line, the remote operation console can specify them. It operates to retrieve arbitrary information from the peripheral device and record it on a part of the film. With this, an operator such as a doctor can record the identification information of the subject on a part of the film while being located at the remote operation console in the operation room, and automatically record the imaging information at the time of the inspection. Information can be transmitted to the information input / output device.

A fluoroscopic imaging stand including a quick-shooting device 1 to be provided, an X-ray tube device (not shown), a top plate on which a subject is laid, and the like is installed, and these constitute an X-ray fluoroscopic imaging device. Then, in response to a control command from the remote operation console 8, X-rays are radiated to the subject from the X-ray tube device of the fluoroscopic imaging table, and a transmitted X-ray image of the subject is photographed on the film 6 of the quick-shooting device 1. It is supposed to do.

In such an X-ray fluoroscopic imaging apparatus, according to the present invention, the remote operation console 8 is provided with an information reading device 9 and a display control device 12, which is a film transporting device section of the fluoroscopic imaging table. The quick recording device 1 is provided with an information recording device 13, and the fluoroscopic imaging stand control device 14, the X-ray generation control device 15, and the quick transfer control device 16, which are peripheral devices, are mutually connected via the remote operation console 8 and the communication line 17. It is connected. In FIG. 1, reference numeral 18 indicates a control unit in which the control function units of the remote control console 8 are collected.
In addition to 2, a central processing unit (CPU) 19 as a control device for controlling the whole and a clock 20 having a clock function
And an optional read / write memory (RA for storing input data
M) 21 and read-only memory (R
OM) 22 and an input / output terminal 23 for exchanging signals with peripheral devices and the like.

The information reading device 9 serves as a means for reading the identification information from the identification card or the medical record 24 or the like in which the name, age, sex, etc. of the subject are entered, and the charge-coupled device (CCD) is aligned on a straight line. Further, it has a CCD line sensor or an image scanner 25 arranged in an array, and sequentially scans and reads the identification information written in the medical chart 24 and outputs a digital signal.

It has an input / output terminal 11 for inputting / outputting information in communication with the outside, and can be connected to a printer or the like for printing out internal information. Normally, as shown in FIG. 2, it is used in juxtaposition with the remote operation console 8. As the computer device 10 used here, a personal computer or the like is used because of factors such as function and price.

The display control device 12 includes the information reading device 9 described above.
Alternatively, it serves as a means for inputting and storing the signal of the identification information read by the input / output terminal 11 and controlling the display of the remote operation console 8 or the display on the information recording device 13 described later. It has a read / write memory (RAM) 31 for storing a digital signal of identification information at any time, and a CPU 32 as an individual control device for controlling the display of the photographing state or the display of the identification information read from the RAM 31.

The information recording device 13 is the display control device 1 described above.

Here, when the imprinting display 33 is a transmissive liquid crystal display, the liquid crystal display does not emit light by itself, and the contrast of characters on the display is low, and the X-ray is not used as it is. Since it is difficult to see on film, the exposure time must be extended. Therefore, as shown in FIG. 1, by using a liquid crystal display as the imprinting display 33, which has a planar light emitting source 36 on the back side or a liquid crystal display with a backlight, the display is performed. The contrast between information such as letters and the background is strengthened. As a result, the information displayed on the imprinting indicator 33 can be imprinted on the film 6 in a short exposure time.

Similarly, the X-ray generation control device 15 as a peripheral device controls the tube voltage and the tube current applied to the X-ray tube device provided on the fluoroscopic imaging table, and has a CPU 38 as an individual control device therein. have. Further, the quick-shooting control device 16 which is also a peripheral device mechanically controls the sequence of the quick-shooting device 1 that conveys the film 6 to the radiographing position of the transmission X-ray on the fluoroscopic imaging stand, and sends an information imprinting signal. However, it has a CPU 39 as an individual control device therein. Then, the CPUs 37, 38 of the respective peripheral devices (14, 15, 16),
39 and the input / output terminal 23 in the control unit 18 are mutually connected by the communication line 17.

As a result, the CPU 19 for controlling the entire remote control console 8 is used as a master unit, and the CPUs 29, 30, 37,
38 and 39 are serially connected as slaves, and various kinds of information can be constantly communicated between the remote operation console 8 and each peripheral device via the communication line 17. At this time, in the communication line 17, the CPU 19 of the remote operation console 8 sends the address of the CPU of the partner device with which the user wants to communicate, and only the device to which the CPU designated by this address belongs communicates with the remote operation console 8. , Communicate information with each other. By mutually connecting with the communication line 17 in this way,
Since the remote control console 8 can communicate only with the place where the user wants to communicate, when the user wants to add new information to be imprinted, simply connecting a peripheral device to the communication line 17 enables the information to be freely transmitted. Obtainable.

Further, the input / output terminal 23 has a terminal for communication with the input / output terminal 11 for the external computer device 10, and is equipped with an RS232C interface which is usually used for communication of a personal computer. . As a result, it is possible to input the identification information of the subject from the computer device 10 or input information such as imaging conditions to the X-ray device based on the identification information, and conversely from the X-ray device side. It is possible to output shooting information such as shooting conditions and the number of shots to the computer device 10 side for storage and printing out by a printer.

Next, the operation of the X-ray fluoroscopic imaging apparatus thus constructed will be described. When an operator such as a doctor examines a certain subject, first, the name of the subject,

At this time, a sensor (not shown) such as an optical sensor for detecting that the chart 24 or the like is inserted is provided at the insertion port of the reading unit 27 to detect the position of the end of the chart 24 or the like. Then, the fact that the chart 24 or the like has been inserted is notified to the display control device 12 shown in FIG. The display control device 12 sends a scanning signal to the scanning mechanism section 26 via the signal line 40 in response to the input of the insertion sensing signal of the chart 24 or the like. Then, the scanning mechanism unit 26 is driven to move the information reading device 9 at a right angle to the longitudinal direction of the image scanner 25, for example, in the direction of the arrow B by a predetermined distance, and scans the chart 24 or the like.

As a result, the identification information entered in the medical record 24 or the like is automatically read by the information reading device 9.
Then, the read digital signal of the identification information is input to the display control device 12 through the signal line 41, and is stored in the RAM 31 under the control of the internal CPU 32.
Contrary to the above, the information reading device 9 is fixed,
Even if the chart 24 or the like is scanned and moved in the direction opposite to the arrow B direction by an appropriate sheet conveying means, the identification information can be similarly read.

At the same time that such an operation is being performed, the operator photographs the subject. And
When the photographed film 6 is conveyed to a predetermined place by the quick-shooting device 1 each time one image is taken, the quick-shooting control device 1

Time, X-ray exposure conditions, etc. are displayed. At this time, the light emitting source 36 on the back side is turned on in order to increase the display contrast. In this way, the identification information displayed on the imprinting display device 33 is stored in the optical system 35 of the information recording device 13.
Is reduced or enlarged to a certain size, and is imaged (34) on the film 6 and imprinted.

When the exposure time determined by the program elapses, the display on the imprinting indicator 33 disappears and the imprinting of information ends. By such an operation, the identification card or the chart 24 can be displayed on the remote operation console 8.
It is possible to read the identification information such as the name, age, and sex of the subject from the above, and imprint it on a part of the film 6 on which the transmission X-ray image of the subject is photographed.

Further, when the identification information of the subject is input and read from the external computer device 10, the operation of inputting information to the computer is omitted, but it is assumed that the information is already stored in the computer. The identification information is communicated by the transmission method standardized by the RS232C interface or the like by the operation of the computer device 10,
The CPU 19 reads necessary identification information such as the name, age, and sex of the subject, and the content is RA in the display control device 12.
It is stored in M31. Thereafter, the identification information of the subject read from the RAM 31 under the control of the internal CPU 32 is input to the imprinting display 33 of the information recording device 13 under the control of the CPU 19, and the imprinting display 33 is provided. The identification information of the subject is displayed on. After that, the identification information of the subject is imprinted on a part of the film 6 that has been photographed by the same operation as described above.

Further, it is possible to write photographing information such as photographing conditions and the number of photographed images in the examination on the subject and personal data such as exposure dose. As a result, it is possible to perform radiation exposure management for each subject. When the identification information is the identification card or the chart 24 and the computer device 10
When the chart 24 is inserted, the detection sensor detects that the chart 24 or the like at the insertion port of the reading unit 27 is inserted, and when the chart 24 is inserted, the information of the chart 24 is selected. Alternatively, if it is not inserted, it is possible to switch to select information from the computer device 10.
