Description

The present invention relates to an X-ray image recording medium (imaging plate = Im) formed by applying a stimulable phosphor to a sheet-like medium.
aging Plate; hereinafter, referred to as IP. More particularly, the present invention relates to a cassette-type X-ray radiography apparatus capable of using various types of IPs in one apparatus.

[Conventional technology]

As is already known, IP can repeatedly use photographing (accumulation of image information) and erasure, and the quality of an image can be variously changed by image reproduction processing, and X-rays can be transmitted to a subject. In recent years, the field of use in X-ray diagnosis has been expanding from the surgical area and the chest area to the gastrointestinal tract area.

As is well known, an X-ray fluoroscopy table equipped with an X-ray flash is used for X-ray diagnosis of the digestive tract. At present, in Japan, the remote control system is the mainstream of the X-ray fluoroscopy table, and most of the flash units are of the cassette type X. To this end, various technologies for transporting IP alone have been developed and some have been commercialized.

In order to obtain an X-ray image using IP, it is necessary to read out the X-ray information recorded in IP and perform image reconstruction processing, which is equivalent to the conventional X-ray film development processing. I do. The dedicated device performs supply, transport, and storage operations for processing the IP, and a dedicated magazine is provided for supplying and storing the IP.

The above-mentioned commercially available X-ray radiography apparatus using IP is equipped with a supply magazine and a storage magazine dedicated to the X-ray radiography apparatus. The photographed IP is transferred from the storage magazine of the X-ray radiography apparatus to the supply magazine of the IP image processing apparatus. It needed to be replaced.

In order to eliminate the work of replacing the IP, an attempt has been made to share the magazine of the X-ray flash apparatus and the magazine of the IP image processing apparatus. When this magazine is shared, the supply magazine of the IP image processing apparatus is used as a storage magazine in the X-ray rapid imaging apparatus. Normally, the supply magazine is very difficult to use as a storage magazine because a brush-like member is provided inside it to take out only one recording medium such as film or IP stored in a stack. It is. As a solution to this difficult problem, the present applicant has previously proposed a forced storage mechanism in Japanese Patent Application No. 1-43021.

On the other hand, it is common to record data such as the name of the subject and the date of imaging on the X-ray image. This record is X
In the case of the line film, the exposure method is used, but in the case of the IP, the method cannot be adopted, and the bar code method is adopted. According to the barcode method, a barcode obtained by coding IP identification information on each IP in advance is attached to a predetermined position on the back surface of the IP. In order to transmit the IP identification information from the X-ray apparatus side to the IP image processing apparatus side, the X-ray flash apparatus has a built-in barcode reader for reading the identification information of the IP taken by the X-ray. The IP identification information read by the barcode reader is sent to the IP image processing device, where it is collated with the subject information and output and displayed.

Incidentally, the diagnostic region of the digestive tract covers a wide area of the esophagus, stomach and intestine. To cover this wide diagnostic area, X
There is an apparatus in which a line speed photographing apparatus is loaded in various sizes, for example, a quadruple format, a continental format, and a large size format are appropriately selected or appropriately combined. Naturally, there has been a demand for the development of a multi-size IP compatible cassette-type X-ray radiography apparatus capable of using IP.

[Problems to be solved by the invention]

As mentioned earlier, the supply magazine has brush-like members inside, making the internal space very tight for IP. Thus, the supply magazine is separated for each size. In a system in which the supply magazine of the IP image processing apparatus is a storage magazine of the X-ray radiography apparatus, it is not possible to store various sizes of IPs that have been X-rayed in one magazine. Therefore, in the X-ray photographing apparatus, as a method of multi-sizing, a supply magazine and a storage magazine of one size are paired, and when switching to a different size, a method of changing the size of the pair (1 channel multi-size) Method) or a method (multi-channel multi-size method) in which a supply magazine and a storage magazine can be loaded by the number of pairs of sizes for two or more sizes.

However, as described above, it is difficult to use the supply magazine for the IP image processing apparatus as a storage magazine, and some kind of forced storage mechanism is required. Therefore, the forcible storage mechanism must be adapted to that.

If the position of the barcode attached to the IP differs depending on the size, it is necessary to consider the support of the barcode reader.

Accordingly, it is an object of the present invention to provide a technology that enables a single cassette-type X-ray radiography apparatus to use IPs of a plurality of sizes.

More specifically, it is an object of the present invention to provide a rapid shooting device which is suitable for a single-channel multi-size system, includes an IP forced storage mechanism and a bar code reader, and can supply a magazine for an IP image processing apparatus as a storage magazine. .

[Means for solving the problem]

In order to achieve the above object, the present invention provides a supply magazine for stacking and storing an unphotographed stimulable phosphor sheet with a barcode provided at a predetermined position on the back surface according to the size, and a takeout mechanism and a transport mechanism. A rapid shooting mechanism for moving the conveyed stimulable phosphor sheet between the photographing preparation position and the photographing position, a storage magazine for accommodating the photographed stimulable phosphor sheet, and a storage magazine provided for each stimulable phosphor sheet. In a cassette telescopic X-ray radiography apparatus having a barcode reader that reads a barcode along a transport path from a supply magazine to a storage magazine, a storage magazine in which a storage space is formed for each of the stimulable phosphor sheets of different sizes is used. A magazine loading mechanism that can be loaded as an alternative, and a shooting mechanism that is provided above the opening of the loaded storage magazine in the direction of movement toward the bottom plate of the storage magazine. A pressing mechanism having a plurality of pressing members for pressing the stimulable phosphor sheet into the storage magazine,
A mechanism for variably setting the set positions of the plurality of pressing members in accordance with the size of the storage magazine to be loaded.

When the pressing mechanism is provided with a positioning mechanism for centering the stimulable phosphor sheet in accordance with the opening of the storage magazine, the effect of the operation of the pressing mechanism is further enhanced.

Further, as a mode of the mechanism for variably setting the set position of the pressing member, a mechanism that moves the member by an electric method and a manual method that moves the member by the force of an operator who loads the storage magazine can be adopted. . When the latter manual method is used, gravity can be used to reduce the operating force.

Further, the present invention variably sets the position of the barcode reader in accordance with the position of the barcode attached to the stimulable phosphor sheet, and provides a position setting mechanism for the barcode reader to change the position of the pressing member. The above-mentioned object is achieved by interlocking with.

[Action]

The plurality of pressing members whose position can be set of the forcible storage mechanism according to claim 1 are set corresponding to the size of the magazine to be loaded, and have been photographed from above the opening of the loaded magazine toward the bottom plate of the magazine. Push in the stimulable phosphor sheet. Therefore, even if the storage space of the storage magazine is a very tight space for storing the stimulable phosphor sheet, the stimulable phosphor sheet can be stored, and furthermore, the storage magazine has IP image processing. Even if a brush-like member or the like is provided on the side of the storage space for use as a supply magazine in the apparatus, the stimulable phosphor sheet can be stored against the resistance. When the size of the magazine (the size of the opening) differs, the positions of the plurality of pressing members are set correspondingly. Therefore, a plurality of stimulable phosphor sheets of a plurality of sizes can be used by one rapid shooting apparatus, and the stimulable phosphor sheet taken out can be immediately loaded into the IP image processing apparatus.

According to a second aspect of the present invention, the positioning mechanism receives the photographed stimulable phosphor sheet conveyed above the opening of the storage magazine, temporarily holds the sheet, and then centers it on the opening of the storage magazine. Thereafter, when the pressing member is moved toward the bottom plate of the magazine, the stimulable phosphor sheet can be smoothly pushed into the storage magazine.

The barcode moving mechanism according to claim 3, when the stimulable phosphor sheet is loaded in the rapid-moving apparatus, even if the position where the barcode is provided is different between the stimulable phosphor sheets having different sizes. Can be read.
