Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an X-ray imaging device, and particularly to an
The present invention relates to a device equipped with a mechanism suitable for input/output.

[Background of the invention]

It is of little use unless a large amount of X-ray film is digitized and filed along with information for identifying the urn and image (for example, patient number, patient name, date of birth, etc., hereinafter referred to as ID). For this reason, when digitizing IDs, there is a method of inputting each ID one by one, but it is not practical as it takes a huge amount of time and input errors may occur, resulting in inaccuracies. What you input is becoming important.

For this reason, patent 6G-82660. Patent application 60-2579
75 methods have been proposed. However, patent 60-
The method of pasting a barcode label with an ID recorded on the X-ray film of the 82660 requires a lot of effort as the work of pasting the barcode label in correspondence with the film must be done manually. . Also, patent 6
0-257975, the photographed film has
There is a method of imprinting an ID, but the imprinted ID
The image may vary depending on the device.

Some images are blurred or have capricorns that are difficult to distinguish, and the reality is that it is not possible to distinguish the images reliably.

[Purpose of the invention]

An object of the present invention is to eliminate the above-mentioned drawbacks, and to ensure that ID
The object of the present invention is to provide a device that allows input of information.

[Summary of the invention]

Conventionally, there is a possibility that the photographed film may be out of order after it passes through the automatic processor until it is input to the film digitizer.For example, in an x11A camera that handles several film sizes, the storage magazine As shown in Figure 6, there is no problem when storing the large-sized film 29 in the storage magazine 28 and then storing the four-sized film 30, but when storing the next film 31, Nose size film 30
Depending on the position of the film, it may not get caught, but if the film is at the back, it may get caught and slip under the four-sized film 30. For this reason, there is no guarantee that the order in which the films are stored will be maintained.
The structure is such that input is made to the film digitizer while maintaining the order at the time of shooting, and at the time of shooting, an ID is filed in a memory and is input to the digitizer in correspondence with the film. Figure 1 shows an overview of this system.

An X-ray imaging device 1 has a magazine that takes images with several types of film sizes, inputs 10, and stores several types of film sizes in a mixed manner, takes out the film from this storage magazine, develops it, stores it, and transfers the ID to the storage magazine. This automatic processor system 2 and this automatic developer system 2
The system comprises a film digitizer system 19 which takes out a film from a storage magazine, digitizes it, and reads out an ID as the film ID.

X-ray imaging device! 1 irradiates X-rays 5 with an xg high voltage device 7 and an x#i tube device 4, transmits through a subject 6, and then imprints it on an X-ray film 9 as an X-ray image. It is taken out from the supply magazine 10 or 11 in advance and photographed. After that, they are stored in the storage magazine 12. However, if films of different sizes are stored, the order may be mixed up, so make sure that the order is not changed, and input the ID using the ID input device. The data is stored in the memory 12'. This results in a one-to-one correspondence between the film stored in the storage magazine and the ID stored in the memory.

This storage magazine is attached to the automatic developing machine 13, taken out by the film take-out pad 14, and developed and fixed by the fixing section 17.
The developed film 16 is stored in the storage magazine 18 again. At this time, the ID memory 12' of the storage magazine 12 is read out in sequence according to the film, and -
The file is then stored in the buffer memory 15. Furthermore, if the film is detected normally by the film detector 17',
The ID of the buffer memory 15 is stored in the ID memory 18' of the storage magazine 18. If the film is not detected, it is determined that a trouble occurred during the process and the film has become useless, and the ID is canceled.

In this way, the storage magazine 18 stores film and I.
D can be stored correspondingly, so it is attached to the film digitizer 19, the film is taken out with the suction pad 20, the light beam is scanned over the film surface by the light emitting source 21 and the scanning mirror 22, and this transmitted light is The light is received by the photodetector 22, digitized by the A/D converter 24, and filed in the image memory 25 as image data 26. On the other hand, along with the film digitizer, the ID in the storage magazine 18
The data in the memory 18' is read out, and the data in the image memory 25 is read out.
Memory in area D. With this configuration, the photographed X-ray film and the ID can be digitized in correspondence with each other and filed.

Among these, the present invention relates to an X-ray imaging device.

[Embodiments of the invention] An embodiment of the present invention will be described below.

Fig. 2 shows the configuration of the present invention, and Fig. 3 shows the relationship between the position of the stopper in the storage magazine and the number of films stored.
Table 1 shows the IDs to be input, and Table 2 shows the contents of the IDs stored in the ID memory in the storage magazine.

In FIG. 2, an X-ray imaging device capable of taking images in large-angle size and quadrilateral size, and a device for inputting the ID of the patient being imaged;
Two types of film sizes can be mixed and stored. Consists of a storage magazine.

For example, when shooting in a four-size image, select the four-size size using the film size input device 32, take out the film from the cutter supply magazine 11 using the suction pad 51, and remove the film from the film holder, intensifying screen, etc. Film holder 9
At the same time, an X-ray generator is sent out to '! ! 7, the X-ray tube device 4 generates X-rays 5, irradiates the subject 6, and records the transmitted image on the X-ray film 9.

When the X-ray film 9 has been photographed, the storage magazine 1
Send to 2. On the other hand, before taking a photo, enter your ID number, name, date of birth, etc., as shown in Figure 4, using an ID input device such as a computer! ! 8, and when the photographing is completed and the film is detected by the film detector 33, the ID is transferred to the ID memory 39 of the storage magazine 12.

The storage magazine contains an ID memory 39, a film stopper 48 for adjusting the storage position of the film, and a circuit for controlling the same.

When the four films begin to be stored, the film detector 33 detects the film, and based on this signal, the ID memory write/read signal generation circuit 51 generates an ID write signal 52.
At the same time, the number of films is counted by inputting it into the film counter 37. Output 38 of this counter 37
The ID is written in the ID memory 39 using this address as the address. The contents are shown in FIG. The position of the film stopper 48 is controlled by converting it into an analog signal in the D/A converter 40. The stopper is film stopper 48.
The motor is rotated by a drive motor drive circuit composed of a resistor R44 and a differential amplifier 43. Controls the position of film stopper 48.

From now on, each time the film is stored, the film stopper 48 is controlled so that the film is always stored on the input side by moving in accordance with the film position, as shown in FIG.

On the other hand, when a large-angle size film arrives, the ID is input in the same way as for a four-size film, but the signal selection switch 42 is switched in response to the film size selection signal 34, and the stopper position signal is changed to the stopper retraction signal 41. As a result, the stopper is retracted and the film is stored without being caught by the stopper.

In this way, if a four-size film is stored at the back of the magazine, for example, when the first film is stored, it will get caught and go below the previous Seimei film. However, according to the present invention, the Nishimei film is always stored on the input side with a stopper, so it will not get caught. Therefore, the order in which the film is stored will not be messed up. In this way, the storage magazine for,
Even when films of different sizes are stored, the order is always maintained and they can be stored in correspondence with the ID.

In the present invention, the explanation was made using two types of film sizes, but 3~
It is possible to use multiple sizes of 4 types by increasing the types of stoppers and moving them individually.Also, as explained with the stopper that moves according to the number of films, as long as the order does not change when storing the films, Any method is acceptable.

Furthermore, although we explained that the ID memory is built into the storage magazine, this memory can be taken out to store magnetic cards and IC cards.
It may also be written in a memory such as a card and moved in correspondence with the storage magazine.

〔Effect of the invention〕

According to the present invention, the X-ray film and ID can be matched at the time of X-ray photography, and at the time of film digitization, image data and
ID data is compatible, so you can eliminate the hassle of matching the film and ID.

Since this can be done automatically, reliability is also increased.
