Description

[Detailed Description of the Invention] [Field of the Invention] Undeveloped IJJ is a method for supplying a radiation image conversion panel using a stimulable phosphor to an apparatus system used when implementing a radiation image conversion method. , regarding how to accommodate.

[Technical background and prior art of IJJ] When certain types of phosphors are irradiated with radiation (X-rays, α-rays, β-rays, γ-rays, electric T-rays, ultraviolet rays, etc.), part of this radiation energy is released. It is known that the phosphor is accumulated in a phosphor, and when this phosphor is irradiated with excitation light such as visible light, the phosphor exhibits stimulated luminescence depending on the accumulated energy. The body is called 7i laminated phosphor (stimulable phosphor). Using this stimulable phosphor, radiation image information of a subject such as a human body is recorded on a radiation image conversion panel (stimulable phosphor sheet) that partially has a sheet-like stimulable phosphor layer, and the radiation image conversion A panel is scanned with excitation light such as a laser beam to generate stimulated luminescence light, the resulting stimulated luminescence light is read photoelectrically to obtain an image signal, and based on this image signal, a radiation image of the subject is photographed. A radiographic image information recording and reproducing system that outputs visible images to recording materials such as materials, CRTs, etc. has already been proposed by Mizu Applicant (Japanese Patent Laid-Open No. 55-12
No. 429, No. 58-11395, No. 55-16347
No. 2, No. 56-104645, No. 55-116340
number, etc.).

The radiation image conversion panel in the above system stores and records radiation image information and temporarily holds the recorded image information until it is read by the excitation light scanning, and therefore, the reading of the image information is completed. After that, it is desirable to erase the image information remaining on the panel and use that panel for ilJ.

Therefore, based on the above-mentioned demands, a radiation image information reading device has been proposed which includes a reading section that reads image information recorded on a panel and an erasing section that erases the image information remaining on the panel. ing.

In the L-number ray image information reading device, a cassette that houses and holds a radiation image conversion panel that has been photographed by an external imaging device is loaded into the cassette holding section, and the radiation image conversion panel is taken out from the L-number cassette. The image information is sent to a reading section to be read, and the image information remaining on the panel that has been read is further erased by an erasing section. The panels that have been erased are taken out of the reading device and are ready to record image information again, but these erased panels are once placed in the collection tray inside the reading device. It is common for the entire stacked tray of panels to be removed from the device. The panels accumulated in the accumulation tray need to be accommodated in the cassette as described above when a new photograph is to be taken, so it is necessary to load the panels one by one into the cassette prior to photographing. This loading is done by a dedicated loader or manually, but if a dedicated loader is used, the cost of the entire system increases, and if one manual loading is performed, a radiation image conversion panel is required. There is an inconvenience in that it is not preferable in terms of handling the panel since it is directly touched by hand.

Therefore, it may be possible to eliminate the need for the panel taken out from the cassette to be sent to a reading section and an erasing section for reading and erasing, and then to be carried into the cassette again for loading. However, in conventional devices, cassettes are loaded one by one into the cassette holder, so when returning a panel to the cassette as shown in Then, the next cassette cannot be loaded into the device until the panel inside the cassette is taken out, read, erased, and placed back into the cassette, making the work of loading and unloading the cassette into the device complicated. The problem arises that That is, in many cases, the reading device has to process multiple panels in succession, and in particular in IM imaging devices, images are taken continuously, and the cassettes with #M shadows are sequentially transferred to the reading device. In order to operate the 2-reader without waste, it is necessary to change the cassettes each time the processing for one panel is completed in the reader. There is an inconvenience that the user has to wait with the cassette that has been photographed, which increases the time required to replace the cassette, making the replacement work complicated and inefficient.

Purpose of the L-blade with one blade] The purpose of the unreleased Ill is to provide an effective method for supplying and storing radiation image conversion panels in order to enable more efficient implementation of the radiation image conversion method.

[Summary of IJJ] The present invention accommodates and holds a radiation image conversion panel on which radiation image information is recorded, and has two or more cassettes each having an introduction/ejection section at one end, with the introduction/ejection section facing downward. Then, engage the panel holding release auxiliary means with one portrait cassette in the prescribed order to release the holding of the panels, and sequentially drop the radiation image conversion panels housed in the cassettes.
At the same time, move the empty cassette so that its introduction/ejection part faces upward, and then engage the panel holding release assisting means with the cassettes in a desired order to release the panel holding state, and then record image information. The present invention provides a method for supplying and accommodating radiation image conversion panels, which comprises dropping and accommodating radiation image conversion panels in a ready state into a cassette.

In addition, the present invention provides a cover that accommodates and holds a radiation image conversion panel on which radiation image information is recorded and is provided with a panel introduction section at one end and a panel ejection section at the other end.
Two or more cassettes are arranged with the panel ejection section facing downward, and the panel holding and release assisting means are engaged with the panel ejection section of the cassette in a desired order to release the held panels and eject the panels. The radiation image conversion panels housed in the cassettes are sequentially dropped and taken out from the cassettes, while the panel holding release assisting means are engaged with the cassettes in the desired order in the panel introduction section of the empty cassettes to release the panel holding form 1 m. A method for supplying and accommodating a radiation image conversion panel is characterized in that the radiation image conversion panel in a state capable of recording one image information is dropped into a cassette and stored therein after releasing the image information.

[Effect of the Invention 1] By using the method for supplying and accommodating a radiation image conversion panel of the present invention, the radiation image conversion method can be carried out more efficiently.

That is, in the method for supplying and accommodating radiation image conversion panels of the present invention, a plurality of cassettes containing panels are arranged in the panel supply section with the introduction/ejection section facing downward. There is no need to load the cassettes into the panel supply section one by one; for example, a large number of cassettes can be moved all at once and then loaded into the panel supply section by a single operation.

In addition, in order to take out panels from a plurality of cassettes (as described above and supply them to the panel transport system or panel processing system), separate panel holding/release assisting means are engaged with the cassettes in the desired order. By releasing the panel holding state of the cassette, the panels in the cassette are sequentially dropped, so it can be carried out very easily.

That is, by using the radiation image conversion panel supply φ accommodation method of the present invention, radiation! Even in situations where the shooting operation time fluctuates irregularly in the shooting system, radiate!
Since the a-image reading device can be operated at all times, its operating rate is improved, which improves the overall processing speed including photographing operations and reading operations. That is, by using the radiation image conversion panel supply dispute settlement method of the present invention, the radiation m The processing efficiency of the entire image recording rip raw system is improved.

Furthermore, tree 9. By using Akira's method of supplying and storing radiation image conversion panels, panels can be taken out from multiple cassettes installed in the panel supply section, depending on the order of loading the cassettes or the order of recording on the panels (the order of recording on the panels). They can be performed in any desired order without being restricted by the order. As a result, it is possible to preferentially read out radiation images recorded on a specific radiation image conversion panel, and it is also possible to meet the desire to know the radiation image of a specific patient as soon as possible.

Furthermore, according to the supply meeting accommodation method of the present invention.

After photoelectrically reading the radiation image from the panel in the radiation image reading device and erasing the radiation image remaining on the panel after reading, the panel is removed from the cassette in a state where it can be photographed (recorded) again. Since it can be collected into a cassette by the same operation as the method used to take it out, it can be said that the efficiency of the radiation image conversion method has been further improved.

Therefore, for example, it is possible to omit the work of loading the panels that have been read and erased and stacked on the stacking tray one by one into empty cassettes, either manually or using another device such as a loader. .

It becomes possible to attach the cassette to the radiographic image capturing apparatus and use it to image a new patient.

[9, Detailed description of S1] The radiation image conversion panel supply storage method of the present invention is explained using the radiation image of figure fjS1 used for reproducing the radiation image already recorded on the radiation image conversion panel by radiography.

As 23a' and 23b', the electromagnetic solenoids used in the apparatus shown in FIG. 4 can be suitably employed in this apparatus as well.

By the way, the cassette 50 used in the two-legged device, like the cassette 20 exemplified above (see FIG. 3), engages with the panel holding release auxiliary means to easily release the panel holding of the cassette and te. In addition, one end thereof is provided with a panel introduction portion, and the other end thereof is provided with a panel ejection portion. The shape of such a cassette with open ends is shown in FIG.

FIG. 6 is a perspective view of a cassette with open ends. FIG. 6-A is a sectional view taken along line mm in FIG. 6, and FIG.
Figure B is a sectional view taken along the line m'-m' in Figure 6.

The basic structure of the cassette 50 is the same as the cassette shown in FIG. 63a, 63b, 64a, 64
Consists of b. However, at both ends of the f-plate panel storage device 61, there are panel introduction portions 65. Panel discharge section 66

Similar to the cassette 20 illustrated in FIG. 3 above, it can be employed in this case as well.

The IJ1 device described above can read radiation images as shown in FIG. You can place it inside the line and use it to your advantage.

Therefore, the panel ejected from this device cannot be read.

After the data is erased, it is collected in this device.

The supply and storage functions of the device will now be briefly explained with reference to FIGS. 5 and 6.

When opening a desired cassette 50 to take out a panel, the motor 53d is driven to move the shelf member 51 so that the panel holding/release assisting means 23a, 23b (not shown) are located below the cassette 5o. In other words, the shelf member 51 is moved to a position where the tips of the panel holding/release assisting means 23a, 23b can be engaged with the engagement-r stages (retaining holes) 68a, 68b of the cassette 5o. Then, when the tip end is engaged with the engagement hole, the panel clamping state of the cassette 5o is released, and the panel P naturally falls by its own weight via the panel ejecting section 66 of the cassette.

That is, by performing the above-described operations on any cassette, any panel can be taken out in a desired order.

The radiation image conversion panel that has fallen from the cassette as described above is read and erased, and then transported to the radiation image conversion panel supply/accommodation section A by the transport system C.

The operation for storing the panels sent from the transport system C into the empty cassette 50 is basically the same as the operation for taking out the stored panels.

When storing a panel that has been subjected to necessary processing into a desired cassette 50, the shelf member 51 is moved and the panel holding/releasing auxiliary means 23a', 23b provided at the 1- and
' is moved in advance so that it is above the cassette 50. That is, the shelf member 5 is moved by driving the motor 53d so that the tips of the panel holding release assisting means 23a' and 23b' are in positions where they can be engaged with the engagement holes 67a and 67b of the cassette 50.

b is opened, and the panel P falls into the cassette via the panel introduction part 65. In this way, the panel P can be accommodated in a desired cassette.

Note that the member having the function of receiving and arranging a plurality of cassettes is a member that arranges two or more cassettes substantially vertically in parallel with their respective planes facing each other as shown in FIG. It does not need to be a shelf member; for example, it may be a disc-shaped member on which a plurality of cassettes are placed radially.
Also, the function of the panel holding release assisting means (including the moving function)
It is also possible to arrange a plurality of cassettes in a receiving arrangement in which the cassettes are suspended or held at the top or side of the cassette to the extent that they do not interfere with the operation of the cassette.

In addition, the feeding device using the radiation image conversion panel feeding/accommodating method of the present invention described in section L is preferably of the -j8 type, and is configured by appropriately imparting a movement function to other basic components. A cassette used in this device may also be used without any particular restriction as long as it has a similar opening ability.

Similar effects can be obtained in these cases as well.
