It has become.

  As shown in FIG. 1, the first casing 18A and the second casing are viewed from the radiation direction in a state where the first portable radiographic apparatus 10A and the second portable radiographic apparatus 10B are overlapped. In the overlapping portion 54 where the body 18B is overlapped, the first casing 18A and the second casing 18B are overlapped so that the second control board 62B does not overlap the first radiation imaging layer 12A.

  Similarly, in a state where the second portable radiation imaging apparatus 10B and the third portable radiation imaging apparatus 10C are overlapped, the second casing 18B and the third casing 18C are overlapped when viewed from the radiation irradiation direction. In the overlapping section 56, the twelfth casing 18B and the third casing 18C are stacked such that the third control board 62C does not overlap the second radiation imaging layer 12B.

The radiation emitted from the radiation source 70 passes through the subject 72 located at the photographing position, and is applied to each portable radiation imaging apparatus 10 after carrying the image information.

  As shown in FIG. 2, in the radiation imaging layer 12, the irradiated radiation such as X-rays is converted into light by the scintillator 30 and irradiated to the sensor unit 14 (see FIG. 6) of the radiation imaging element 13. The sensor unit 14 receives the light emitted from the scintillator 30 and accumulates electric charges.

  As shown in FIG. 6, at the time of image reading, an ON signal (+10 to 20 V) is sequentially applied from the scan signal control circuit 40 to the gate electrode of the TFT switch 16 of the radiation imaging element 13 via the scanning wiring 22. As a result, when the TFT switch 16 of the radiation imaging element 13 is sequentially turned on, an electric signal corresponding to the amount of charge accumulated in the sensor unit 14 flows out to the signal wiring 24. The signal detection circuit 42 detects the amount of charge accumulated in each sensor unit 14 based on the electrical signal that has flowed out to the signal wiring 24 of the radiation imaging element 13 as information of each pixel 20 constituting the image.

  Thereby, image information is obtained by the first radiation imaging layer 12A for the radiation irradiated to the portion where the first radiation imaging layer 12A and the second radiation imaging layer 12B overlap. Further, since this radiation passes through the first radiation imaging layer 12A and reaches the second radiation imaging layer 12B, image information can also be obtained by the second radiation imaging layer 12B.

  As described above, the image information is obtained from the first radiation imaging layer 12A and the second radiation imaging layer 12B, and the two pieces of image information are combined to obtain an image of the overlapping portion 54. Note that an image can also be obtained in the overlapping unit 56 by combining two pieces of image information.

  That is, as shown in FIG. 5A, a long image with no image missing at the seam (image missing as shown in FIG. 5B) can be obtained.

That is, the control board 62 is not arranged in the range X. Thereby, for example, the range X is overlapped with the end side of the other portable radiographic apparatus, so that the radiation irradiated in the overlapping portion reaches the radiation imaging layer of the other portable radiographic apparatus, and this radiation imaging layer Outputs an image signal indicating a radiation image corresponding to the radiation dose. Thereby, it is possible to obtain a long image with no image missing at the joint.

The second control board 82B is not disposed in the overlapping portion 54 where the casing 88A and the second casing 88B overlap.

  By not arranging the second control board 82B in the overlapping portion 54 in this way, even when the positional relationship between the first portable radiation imaging apparatus 80A and the second portable radiation imaging apparatus 80B varies during imaging, the overlapping portion The radiation irradiated in 54 reaches the first radiation imaging layer 86A. Thereby, the first radiation imaging layer 86A outputs an image signal indicating a radiation image corresponding to the irradiated radiation dose.

  Accordingly, by arranging a plurality of portable radiographic imaging devices 80 in a row, it is possible to reliably obtain a long image with no missing image at the seam.

  Next, an example of the portable radiation imaging apparatus set 94 and the portable radiation imaging apparatus 90 according to the third embodiment of the present invention will be described with reference to FIG.

No member other than the radiation imaging layer 96B is disposed in X (predetermined range X). That is, the control board 92B is not arranged in the range X.

  Thus, by providing the second radiation imaging layer 96B up to the end of the overlapping portion 54, the amount of overlap between the first portable radiation imaging apparatus 90A and the second portable radiation imaging apparatus 90B can be reduced.

  In addition, the second radiation imaging layer 96B and the first radiation imaging 96A are overlapped with each other within a range of 2 cm in width as viewed from the radiation irradiation direction. Therefore, by combining the image information from the second radiation imaging layer 96B and the first radiation imaging layer 96A, it is possible to reliably obtain a long image with no image missing at the seam.
