[Problems to be Solved by the Invention] When performing imaging in a hospital room or operating room using the above-mentioned conventional X-ray machine for rounds, it is generally more difficult to set imaging conditions than when performing in a radiology department's imaging room. Shooting requires skill and mistakes are often made.

Therefore, it is desirable to be able to confirm the suitability of photographing conditions at the photographing location.

However, with the above-mentioned conventional X-ray apparatus for medical rounds, it is not possible to know whether the imaging conditions are appropriate unless the film or imaging plate used for imaging is taken back to the radiology department and processed.

Therefore, if the imaging conditions are not appropriate, it is necessary for the radiology department to go to the same imaging location again and perform the imaging, which poses a problem in that it takes a lot of effort and time to retake the imaging.

In addition, when taking pictures during surgery, the above-mentioned conventional
The problem with the X-ray device is that the operator cannot immediately view the image after the image is taken.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an X-ray apparatus for medical rounds that allows the user to immediately view images obtained at the imaging location and to reduce the effort and time required for retaking images.

[Means for Solving the Problems] The X-ray apparatus for medical rounds of the present invention includes an image information reading means for reading image information from an imaging plate, an image display means for displaying an image based on the read image information, and an image information reading means for reading image information from an imaging plate; It is characterized by comprising an image information storage means 18 for storing image information in a removable storage medium.

[Function] In the X-ray apparatus for medical rounds of the present invention, when imaging is completed, the imaging plate used for imaging is sent to the image information reading means to read the image information, and based on the image information, the image is displayed on the image display means. Therefore, the image can be viewed on the spot immediately after the shooting is completed. At the same time, it is also possible to determine whether the photographing conditions are suitable or not.

As a result, if it is determined that the photographing conditions are inappropriate, it is sufficient to retake the photograph on the spot.

Image information read from the imaging plate is stored in a storage medium. After the photographing is completed, the storage medium is removed from the X-ray apparatus, transported to a location where the image recording apparatus is located, and used to record the image on a photosensitive material such as film.

[Example] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Note that this invention is not limited to this.

The transport bag fil17 includes a plurality of rotating rollers 17a,
A suction cup 17b is provided inside the cassette holding part 16 and is movable up and down and back and forth. The suction cup 17b has the function of sucking and pulling out the imaging plate IP in the cassette C. The roller 17a conveys the drawn-out imaging plate IP to the image information reading device 18.

The suction cup 17b is configured to pull out the imaging plate IP immediately when the cassette C is inserted. Therefore, the same cassette C can be used for the next imaging in a short time after insertion.

There is a suction cup 17b on the imaging plate IP drawer.
A rubber roller may be used instead.

Alternatively, the imaging plate IP pulled out from the cassette C may be caused to fall by gravity without using the rollers 17. In this case, it is necessary to provide the image information reading device 18 below the conveyance device 17.

The image information reading device 18 sends the imaging plate IP entered through the rear opening to a reading section (not shown) using a take-in roller 18a. The reading section scans the imaging plate IP with a laser beam to read image information.

When the reading is completed, the paper is sent out from another opening provided on the rear surface by the delivery roller 18b.

- The movement route of IP is as shown by the chain line in FIG.

The imaging plate IP sent out from the image information erasing device 19 is sent into the interior of the magazine 20 from the lower opening and is accommodated as it is.

The magazine 20 is configured such that by opening a lid 20a provided on the side opposite to the opening, the imaging plate IP in the erasure section inside can be taken out from the opening 20b.

As the magazine 20, a known X-ray film magazine or one having a similar structure can be used.

In the chamber 2a, an image information storage device 21 is further provided below the image information reading device 18. Image information storage device 21
The image information read by the image information reading device 18 is stored in a transportable storage medium such as an optical disk.

A CR7 display device 22 is attached to the top surface of the main body 2. The CR7 display device 22 displays an image based on the image information read by the image information reading device 18. A high-definition CRT device can be used as the CRT display device W22.

The CR amount related devices among the above components, that is, the image information reading device 189, the image information erasing device 19, and the image information storage device 21 are shielded with lead plates to avoid the influence of X-rays generated by the above-mentioned X-ray generating device. It is.

As shown in FIG. 3(a), the cassette C has a lid C1 that slides on the top surface of the main body, and by pulling the lid C1, an opening C2 can be formed in the top surface. However, as shown in FIG. 3(b), the opening C2 may be formed by removing the lid C1 provided on the negative side.

Next, a method of using the Mopil type X-ray system M1 having the above configuration will be explained.

First, before moving to the imaging location, the imaging plate IP is stored in the magazine 2o. At least one cassette C of each size may be placed on the cassette C in accordance with the imaging plate IP.

Next, the Mopil type X-ray device W1 is moved to a predetermined imaging location, and there, the imaging plate IP is manually taken out from the magazine 2o and loaded into the cassette C.

Since the imaging plate IP does not have any problem even when exposed to light, it can be loaded immediately at the shooting location without considering the influence of light.

Next, X-ray photography is performed using the cassette C.

When the photographing is completed, the cassette C is inserted into the cassette holding part 16 through the insertion opening 16a, and the lid C1 is pulled rearward. Then, the front part of the cassette C opens, and the suction cup 17b descends to attract the internal imaging plate IP and pull it out from the cassette C. The pulled out imaging plate IP is transferred to the image information reading device 1 by the roller 17a.
It is transported up to 8.

The image information reading device 18 uses a reading section to read image information stored on the imaging plate IP. Then, the read image information is sent to the image information storage device 21 to be stored on the optical disk, while being sent to the CRT display W22 to be displayed as an image.

Therefore, the radiologic technologist can immediately view the image obtained by imaging, and can also judge on the spot whether the imaging conditions are appropriate.

The imaging plate IP that has been completely read is sent to the image information erasing device 19, and the remaining image information is erased. The imaging plate IP is then sent to the magazine 20.

In the case of the second photographing, the empty cassette C is pulled out from the cassette holding section 16, and the previously used erased imaging plate IP is taken out from the magazine 20 and loaded into the cassette C. Then, using the cassette C, photographing is performed in the same manner as described above.

When all imaging is completed, the radiologic technologist removes the optical disk on which the image information is stored from the image information storage device 21, takes it back to the radiology department, processes the stored image information as appropriate, and then transfers it to a photosensitive material such as film. Record as an image.

In the method described above, one imaging plate I
Since images are taken using P repeatedly, there is an advantage that it is not necessary to prepare a plurality of imaging plates IP of the same size.

However, if the imaging is performed using a plurality of imaging plates IP, the imaging can be performed very efficiently.

For example, if three imaging plates IP are used with alternate timings and images are taken in the order shown in Figure 4, three images will be taken while one image is taken with one imaging plate IP. becomes possible.

That is, using the first imaging plate IP, the first
When the cassette C loaded with the first imaging plate IP is inserted into the cassette holder 16 after the first imaging is completed, the first imaging plate IP is immediately taken out from the cassette C. Therefore, the second imaging plate (IP) is loaded into the cassette C, and a second photographing operation is performed.

Next, in the same way, when the second imaging plate IP is taken out from the cassette C, the third imaging plate IP is immediately loaded into the cassette C and a third imaging is performed.

When photographing is performed while exchanging three imaging plates IP in this manner, there is an advantage that photographing efficiency can be increased.

In FIG. 4, "imaging" indicates the process of performing radiography by irradiating X-rays, "insertion" indicates the process of inserting the cassette C used for imaging into the cassette holder 16, and "reading" indicates the process of inserting the cassette C used for imaging into the cassette holding section 16. ``Erase'' indicates the process of erasing the image information remaining on the imaging plate IP, and ``Standby'' indicates the process of reading the image information from the imaging plate IP in the imaging plate 1-IP that has been erased. "Preparation for photographing" indicates the process of loading the erased imaging plate IP into the cassette C.

Furthermore, in the chart for each imaging plate IP, the process described in the upper row indicates that the imaging plate IP is outside the mobile X-ray apparatus 1, and the process shown in the lower row indicates that the imaging plate IP is processed inside it.

In the embodiment described above, the image information erasing device 19 is provided, but it does not necessarily have to be provided. If not, prepare the same number of imaging plates IP as the scheduled number of imaging, and load the next imaging plate IP into the cassette C every time one imaging is completed. The imaging plate IP from which the image information has been read is stored in the magazine 20 as it is, and the image information is erased after being brought back to the radiology department.

Further, in the above-described embodiment, the imaging plate IP is manually loaded into the cassette C, but an automatic loading device such as that attached to a conventional X-ray film developing device may be provided.

[Effects of the Invention] According to the X-ray apparatus for medical rounds of the present invention, images obtained immediately at the imaging location can be viewed, and the effort and time required for re-imaging can be reduced.

Therefore, the burden on the radiologist and the subject is reduced.
