In a radiographic imaging system having an image reading device that attaches an identification code to the radiation-sensitive material, the image reading device includes a reading section that reads the identification code of the radiation-sensitive material, and a radiation imaging system that provides an identification code to the radiation-sensitive material. A storage unit for storing information is provided, and the photographing information and the image information are associated with each other using the read identification code.

[Industrial application field]

The present invention relates to a radiation imaging system that uses reusable radiation-sensitive materials to read image information after imaging.

Technological advances in medical devices have been remarkable in recent years, and in particular, advances in image diagnosis of living bodies have been remarkable.

Among these, even in X-ray equipment that has traditionally been used as radiographic imaging equipment, an X-ray photosensitive material using a photostimulable phosphor called an imaging plate is used instead of X-ray film, which cannot be reused. A device is being developed.

With such an X-ray device, in addition to being able to image the affected area of a living body using the same method as before, the captured image can be obtained from the imaging plate using electrical signals, so compared to conventional film,
It has the advantage that there is no physical deterioration, image processing can be easily performed by digitalization, and the imaging plate can be reused, which is advantageous in terms of cost.

In such an apparatus, a technique for effectively managing reused imaging plates is desired.

[Conventional technology]

FIG. 3 is an explanatory diagram of the prior art.

The imaging device 1 has an imaging plate 10 set opposite an X-ray source 11, and is configured to irradiate a living body M with X-rays from the X-ray source 11, and receive the transmitted X-rays with the imaging plate 10 to take an image. The conventional X-ray film is replaced with the imaging plate 10.

The image reading device 2 reads the photographed imaging plate 1.
0 is set and the set imaging plate 1
0 is read by the image reading unit 20 by scanning with a laser beam and obtained as image information, and stored in the image storage unit 21 such as film or memory.

This imaging plate 10 can be used again once it has been read, and used again for imaging.

The image reading device 2 corresponds to a conventional X-ray film developing device, and by separating imaging and image reading, batch processing is possible, which is convenient for improving imaging efficiency and group medical examinations.

[Problem that the invention seeks to solve]

In such batch processing of reusable imaging plates 10, management of the imaging plates 10 is required.

Since XIJI film cannot be reused, imaging information such as an identification number, examinee number, and imaging date can be imprinted on the X-ray film itself, thereby making it possible to associate the imaging image with the imaging information.

However, since the imaging plate 10 is reused, it is difficult to print such imaging information onto the plate 10.

For this reason, in batch processing, it is necessary to manage the imaging plates 10 in the order of imaging, and to manage the correspondence by having the image reading device 2 read the images in that order.

That is, since it is unclear from the outside appearance which patient the imaging plate 10 is intended for, there is no choice but to rely on human control such as the order of the imaging plate 10.

This method does not pose much of a problem when the number of imaging plates 10 is small, but when the number increases and the order is changed due to an emergency or the like, or the order is changed by mistake, it becomes difficult to correlate with the imaging information. A problem arises.

The present invention provides image information obtained from such a photosensitive material and photographic Vr.
It is an object of the present invention to provide a radiation image system that can accurately perform PH matching.

[Means for solving problems]

FIG. 1 is a diagram explaining the principle of the present invention.

In the figure, the same parts as those shown in FIG. 3 are indicated by the same symbols, 10a is an identification code, which is given to the photosensitive material (imaging plate) 10 for identification, and 22 is a code. A reading unit reads the identification code 10a of the photosensitive material 10 from which an image is to be read, and a storage unit 23 stores photographing information in correspondence with the identification code. The photographing information is obtained and correlated with the image information of the image reading section 20.

[Effect]

In the present invention, by providing the identification code 10a to the photosensitive material 10 and providing the code reading section 21 in the image reading device 2, it is possible to identify which test taker the photosensitive material 10 whose image is being read, that is, the image information is for. It makes it possible to recognize.

If the photographic information in the storage section 22 is selected using the identification code, it becomes possible to associate it with the image information.

In this way, the correspondence between the reusable photosensitive material and the photographic information is accurately performed, and even if the photosensitive material is reused, the management of the photosensitive material becomes easy.
