FIG. 3 is a schematic configuration diagram of an X-ray image reading device which is an embodiment of the radiation image reading device of the present invention.

X-ray film 21 that has been subjected to X-ray photography and development processing
A label 16 printed out by the label issuing device 10 is pasted at a predetermined position. After the label 16 is affixed, the X-ray film 21 is set at a predetermined position in the X-ray image reading device 20, and is conveyed in the direction of arrow Y within the X-ray image reading device 20.

The X-ray film 21 on the transport path of this X-ray film 21
A lamp 22 is placed above the X-ray film 21 to illuminate the X-ray film 21 in a straight line, and a line sensor 22 such as a CCD array is placed at a position facing the lamp 22 with the X-ray film 21 in between. The X-ray film 21 is conveyed from a predetermined position in the Y direction, and when it reaches a position sandwiched between the lamp 22 and the line sensor 23, the light emitted from the lamp 22 creates an X-ray image recorded on the X-ray film 21. The transmitted light is intensity-modulated and transmitted through the line sensor 23.
Analog image signal S for one line in the X direction received by
A is obtained, and by repeating this while conveying the X-ray film 21 in the direction of the arrow Y, an analog image signal SA corresponding to the entire surface of the X-ray image recorded on the X-ray film 21 is obtained. This image signal SA is amplified by an amplifier 24 and A
The /D converter 25 converts the image signal into a digital image signal SD.

Further, a barcode reader 26 is provided at a position corresponding to the label 16 on the conveyance path of the X-ray film 21, and at the timing when the label 16 passes a position facing the barcode reader 26, the barcode reader 2B The barcode IBb written on the label 16 is read.

The image signal SD and ID information thus obtained by this X-ray image reading device 20 are correlated with each other and sent to an optical disk storage device (not shown), and are stored in the optical disk 31 loaded in the optical disk device. be remembered.

The X-ray film 21 that has been read is taken out from the X-ray image reading device 20, and with the label [6] affixed thereto, the X-ray film 21 is stored in a storage (not shown) with reference to the ID information written on the label 16. It is stored and stored in a predetermined position inside the machine.

The image signal SD stored on the optical disk 31 is retrieved using the ID information as a search key, and after the image signal S is subjected to appropriate image processing such as frequency emphasis processing, it is reproduced and output as a visible image for observation. be done. Furthermore, when it is necessary to pull out the stored X-ray film 21, the ID information written on the label attached to the X-ray film 21 is referred to, and the desired X-ray film 2j can be reliably found. .

Incidentally, in the above embodiments, letters and a bar code are written on the label, but it goes without saying that the code referred to in the present invention is not limited to a bar code.

(Effects of the Invention) As explained in detail above, the radiation image reading method of the present invention affixes a label issued by a label issuing device, on which ID information is written in both characters and a code, to a developed film. However, since the radiation image reading device reads the radiation image and also reads the code written on this label, and stores the film with the label attached, the film, image signal, ID information, etc. can always be associated with each other. It happens.
