Abstract

PURPOSE:To allow the checking of the contents of incidental information before imprinting without entailing a cost increase as there is no need for additionally preparing a display means by providing a switching means which switches and outputs the incidental information or diagnostic image. CONSTITUTION:A card sensor 3 detects the correct setting of a card 1 in correct disposition and outputs this detection signal to an image memory 4. The card image photographed by a 1st television camera 2 at this timing is written into the image memory 4. The detection signal is simultaneously outputted to a timer 18 as well and, therefore, the timer 18 starts operating by the prescribed time which is preset. Namely, both an OR gate 19 and an AND gate 21 operate and, therefore, a video switch 15 is so controlled as to be switched to the image memory 4 side. The card image or diagnostic image can selectively be displayed simply by preparing just one unit of a monitor 17 by providing the video switch 15 and, therefore, the contents of the card information are checked before imprinting on an X-ray film 6 without entailing the cost increase.

Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) The present invention relates to an X-ray diagnostic apparatus that imprints incidental information along with an X-ray diagnostic image of a patient onto an X-ray film.

(Prior art) In an X-ray diagnostic device that photographs a patient's X-ray diagnostic image on an X-ray film, not only the diagnostic image but also medical record information such as the patient's name, age, and gender are copied onto the X-ray film as a medical record image. A lot of things are being done.

Such an X-ray diagnostic device is known, for example, from Utility Model Application No. 62-3864.
It is disclosed in Japanese Patent No. 4 and has a configuration as shown in FIG. That is, the memory 22a and CC are stored in the control console 22 in advance.
D22b is built in and the medical record information of medical record 20 is stored in C0D.
After writing the medical record information into the memory 22a by 22b, the medical record information is read out from the memory 22a and displayed on the CRT 16, so that it is imprinted on the X-ray film 12 prepared in the X-ray fluoroscope table 10 through the lens 14.

According to such an X-ray diagnostic device, medical record information is stored in the memory 2.
If you write in 2a, you can take X-rays while keeping your medical records in the doctor's hands.

Furthermore, medical record information can be read out as many times as necessary.

(Problems to be Solved by the Invention) Conventional X-ray diagnostic apparatuses have a problem in that it is not possible to confirm the contents of a medical chart image that should be imprinted on an X-ray film together with a diagnostic image before imprinting it. For this reason, for example, even if a medical record is set in a crooked state, it will be imprinted as is, which may result in useless medical record information. In order to improve this drawback, it would be best to separately prepare a CRT monitor for checking medical record information before imprinting, but this would inevitably increase costs.

The present invention has been made in response to the above-mentioned problems.
It is an object of the present invention to provide an X-ray diagnostic apparatus that can confirm medical record information before imprinting without increasing costs.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an X-ray diagnostic apparatus that imprints incidental information together with an X-ray diagnostic image of a patient on an X-ray film. additional information detection means for detecting whether additional information is set in the part; image storage means for writing additional information based on an output signal from the additional information detection means; and displaying a patient's diagnostic image or additional information. The apparatus is characterized by comprising a display means and a switching means for switching between the incidental information read out from the image storage means or the diagnostic image output from the television camera and outputting either image to the display means. .

(Function) A switching means is provided to switch and output the input supplementary information or diagnostic image, and as necessary, the supplementary information read from the image storage means or the diagnostic image output from the television camera is switched to the display means. Therefore, the contents of the supplementary information can be checked before imprinting by providing only one display means.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the X-ray diagnostic apparatus of the present invention, in which numeral 1 indicates a medical record for recording incidental information such as the patient's name, age, gender, etc.; A first television camera outputs a video signal (medical record image) to an image memory 4; 3 is a medical record sensor provided in a medical record information reading unit (not shown) and detects whether medical record 1 is set; 4 is a medical record sensor that outputs a video signal (medical record image) to image memory 4; Output signal from sensor 3 (
This is an image memory into which a video signal from the television camera 2 is written based on a memory holding command signal.

5 displays the video signal (medical chart image) read from the image memory 4 on a display such as a CRT, and displays the X-ray film 6.
It is a display that can be imprinted on.

Furthermore, a diagnostic image of the patient that has been X-rayed is imprinted on this X-ray film 6. 7 is transparent.

X-ray tube that irradiates X-rays to patient 8 for imaging; 9 is r, r (image intensifier) that converts the X-rays that have passed through patient 8 into an optical image; 11 is I, optical of I9 A second television camera takes an image and outputs a video signal (diagnosis image), and 13 is an X-ray fluoroscopy table.

15 inputs the video signal (medical record image) read from the image memory 4 or the video signal (diagnosis image) output from the second television camera 11, and switches only one of the images based on a switching command. video switching device that outputs
Reference numeral 17 denotes a monitor consisting of a CRT or the like that displays either a medical record image or a diagnostic image outputted via the video switch 15.

In this way, the monitor 17 is used to commonly display the diagnostic image and the medical chart image, but the video switch 15 is controlled so that the diagnostic image is displayed with priority during X-ray fluoroscopic imaging.

18 operates based on the output signal from the medical record sensor 3 to switch the video switch 15 to the image memory 4 for a predetermined period of time.
The output signal from the timer 18 is applied to the video switch 15 as a switching command via an OR gate 19 and an AND gate 21. The operating time of the timer 18 can be arbitrarily varied and set.

24 is a manual changeover switch for arbitrarily switching the video changeover 15 to the image memory rJ4 side, and 23 is an inverter for inputting an X-ray radiation signal for fluoroscopy and photography. O
The R gate 19 becomes conductive when at least one of the output signal from the timer 18 or the output signal from the manual changeover switch 24 is input, and the AND gate 21 becomes conductive when the output signal from the manual changeover switch 24 is input.
It becomes conductive only when the output signal from inverter 9 and the output signal from inverter 23 are both input.

Next, the operation of this embodiment will be explained.

To start X-ray diagnosis of a patient, the patient's medical record 1 is set in a medical record information reading section (not shown).

When the medical chart 1 is set in the correct position, the medical chart sensor 3 detects that the medical chart 1 has been set and outputs this detection signal (memory retention command) to the image memory 4.

As a result, the video signal (medical record image) captured by the first television camera 2 at this timing is transferred to the image memory 4.
written to. At the same time, the detection signal is also output to the timer 18, so the timer 18 starts operating for a preset predetermined time.

That is, since the OR gate 19 and the AND gate 21 operate together, the video switch 15 is controlled to be switched to the image memory 4 side.

Therefore, the medical chart image read out from the image memory 4 is outputted and displayed on the monitor 17 via the video switch 15. This allows you to check the contents of the medical record information before imprinting it.

As a result of this confirmation, if the displayed medical record information is suitable as an image to be recorded on the X-ray film 6, the medical record 1 can be reset and the doctor can freely use it during diagnosis. This medical record information is read out from the image memory 4 and imprinted onto the X-ray film 6 one by one during repeated fluoroscopy and imaging on the X-ray fluoroscopy table 13. If it is inappropriate, if the medical record 1 is set again, it will be detected again by the medical record sensor 3, so the same operation as described above can be repeated until it becomes inappropriate.

Additionally, if it becomes necessary to check the imprinted medical record image during operation, the video switch 15 can be switched to the image memory 4 side at any time by pressing the manual switch 24 unless X-ray exposure is being performed. , you can check medical record information.

In this way, according to the present embodiment, by providing the video switch 15, it is possible to switch and display the medical chart image or the diagnostic image by preparing only one monitor 17, so that the X-ray image can be switched and displayed without increasing the cost. The contents of the medical record information can be confirmed before being imprinted on the film 6. For example, if a medical chart is set in a crooked state, this can be detected by observing the monitor 17, so that medical chart information can always be accurately imprinted.

In this embodiment, the switching of the video switch 15 is controlled by the timer 18.
Alternatively, although an example has been described in which the manual changeover switch 24 is used, the video changeover 15 can be controlled to be switched to the image memory 4 side whenever X-ray exposure is not performed. In other words, there is no diagnostic image when X-ray exposure is not being performed, so the video switch 1
5 to the second television camera 11 side, only a pitch black display is displayed on the monitor 17. Therefore, in this case, it is effective to switch the video switch 15 to the image memory 4 side, since the medical record information can be displayed.

Also, other display devices can be used in place of the monitor 17. In this case, the same effect can be obtained by changing the image switching method in accordance with the characteristics of the display device.

The medical record sensor 3 may be any device as long as it has a function of detecting that the tip of the medical record 1 has come into contact with the deepest part of the medical record insertion opening, and for example, a photosensor, a microswitch, or the like can be used.

Furthermore, the image to be imprinted on the X-ray film 6 together with the diagnostic image may include information other than medical record information.
In this case, a method such as combining video signals may be considered. Further, the medical record information can be read from the medical record and then converted into digital character information using a character recognition device or the like, making it possible to digitize image memory or the like. Furthermore, medical record information can be accessed using the keyboard or ID.
It is also possible to configure the information to be obtained from a card or online data from a hospital information processing computer, and in this case, a complete digital processing system can be realized.

[Effects of the Invention] As described above, according to the present invention, since the switching means for switching and outputting the supplementary information or the diagnostic image is provided,
Since there is no need to prepare an extra display means, the contents of the supplementary information can be confirmed before imprinting without increasing costs.
