DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of an X-ray diagnostic apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the overall configuration of this embodiment. An X-ray tube 14 is arranged above a bed 12 on which a patient 10 is placed, and a spot photographing device 18 that stores an X-ray film 16 is provided below the bed 12. X-rays emitted from the X-ray tube 14 pass through the patient 12 and
By exposing the X-ray film 16 to light, an X-ray transmitted image is photographed on the X-ray film 16. Spot photographing device 18
A name printer device 20 having an image display unit such as a CRT is attached to the camera, and the displayed image is displayed on the spot photographing device 18.
It is designed to be imprinted on the X-ray film inside. C
RT is provided at a position corresponding to the lower right corner of the X-ray film.

On the other hand, a medical record 22 in which patient information such as a patient's name, ID number, and disease name is entered is imaged by a TV camera 24, and an image signal including the patient's name is output from the TV camera 24. Note that the TV camera 24 may take images of patient names not only from medical records but also from other documents in which patient names are written, such as consultation tickets and patient cards. Medical record 2
2 contains various data other than the patient's name, so that the TV camera 24 can easily capture only the patient's name.
A reading frame corresponding to the viewing range of the TV camera is provided on the operation table to which the TV camera 24 is attached. Therefore, by locating the patient name entry column of the medical record within this frame, only the name column in the medical record is imaged. The output of the TV camera 24 is supplied to a video signal synthesizer 26.

The video signal synthesis device 26 includes a timer 28;
A data input device 30 is also connected. The timer 28 outputs a time signal representing the photographing date, hour, minute (may include seconds if necessary), and the data input device 30 is operated by an operator to output arbitrary alphanumeric alphanumeric data. Note that the timer 28 is backed up by a battery.
Even if the device is turned off, it continues to measure time.
Always output the current time.

Details of the data input device 30 are shown in FIG. Here, in order to deal with so-called split shooting, in which one film is divided into left and right, or top, bottom, left and right, we will use numeric keys to specify the number of frames for split shooting, and left and right keys to specify the subject part. A key is provided on the data input device 30. For example, as shown in Fig. 3, when the film is divided into left and right parts and the right side of the patient is photographed in the first sheet (here, the left half), and the left side is photographed in the second sheet (here, the right half). , enter "1R/2L".

The video signal synthesis device 26 has a character generator and generates a time display character signal representing the time signal from the timer 28, and also generates a time display character signal representing the time signal from the timer 28.
Generates alphanumeric signals representing the number of frames starting from 0 and the area to be photographed. Furthermore, the synthesizing device 26 inserts these time display characters or photographed region display characters into a part of the image from the TV camera 24, and superimposes the two. This composite signal is supplied to the name printer device 20, and the composite image is displayed on a display unit such as a CRT. The displayed image is the X-ray film 18 in the spot photographing device 16.
This imprints patient information onto the film.

The operation of the embodiment configured as described above will be explained. When starting to photograph a patient, place the patient's medical record, examination ticket, etc. on the console and set the patient's name field within the reading frame. When the medical records are set, the TV
The camera 24 captures an image within the reading frame, and the image of the patient's name written on the medical chart is input to the video signal synthesis device 26. Note that when performing divided imaging, the number of frames and the region to be imaged are specified using the data input device 30, as described above. on the other hand,
Since the timer 28 always measures the current time and outputs a time signal indicating the shooting date, hour, and minute, the video signal synthesis device 26 adds these time display characters to a part of the image from the TV camera 24. , or insert the imaged part display text and superimpose the two. An example of a composite image is shown in FIG. The part surrounded by the broken line is the superimposed character. Here, TV camera 24
The identification number ("88" in FIG. 4) is input together with the patient name, and characters are superimposed between the identification number and the patient name. After the patient's X-ray imaging is completed, this composite signal is supplied to the name printer device 20, and the composite image is displayed on the display unit such as a CRT, so that the lower right corner of the X-ray film 18 is displayed as shown in FIG. Patient information is imprinted on the image.

[0013] According to this embodiment, the operator can simply set a document such as a medical record in which the patient's name is written into the reading section of the operating console, and the photographing date, time, and time can be read according to the data from the timer. A number indicating the patient's name is combined with the patient name image captured by the TV camera and is imprinted onto the X-ray film. Therefore, there is no need for the operator to write the photographing date, time, minute, etc. in the medical record, and the burden on the operator is reduced. Furthermore, since the data input from the data input device is also combined with the imprinted image, information such as the photographed body part can also be imprinted easily. This facilitates chronological management of shot films. Furthermore, it is also possible to easily confirm which part of the patient was photographed.

The present invention is not limited to the embodiments described above, but can be implemented with various modifications. For example, the data input device 30
Connect hospital information processing computers, etc. online to
By transferring the imprinted data to this computer, patient information at the time of diagnosis can be easily managed. That is, by using the data stored in this computer together with the information imprinted on the film, more detailed management of the exposed X-ray film becomes possible. In addition, the position where the characters are superimposed is not limited to the center of the image between the identification number and the patient name, but the video signal composition device 26 is provided with a composition position designation switch, so that the characters can be superimposed at any designated position. May be synthesized. This makes it possible to handle various types of medical records and patient cards.

[0015]

As described above, according to the X-ray diagnostic apparatus according to the present invention, the timer means for measuring the current time and the timer means for outputting an image from the imaging means for imaging the patient name written in the medical chart, etc. By providing a compositing means that inserts the current time display characters according to the output of , the imaging time can be shortened, and the patient's pain can also be alleviated.
