  • Patent number: 9060731
    Abstract: A comparison circuit 78 of an AEC unit 67 of an electronic cassette 13 compares the accumulated value of a detection signal from a detection pixel 65 of the electronic cassette 13 with an irradiation prohibition threshold value on the electronic cassette 13. When the accumulated value of the detection signal reaches the irradiation prohibition threshold value on the electronic cassette 13, a detection signal having the same voltage value as the irradiation prohibition threshold value of the radiographing condition on the source control device 11 paired with the radiographing condition on the electronic cassette 13 is output from a detection signal I/F 80 of the electronic cassette 13 toward a detection signal I/F 26 of the source control device 11.

  • Patent number: 9060738
    Abstract: A storage and search unit of a console acquires a source ID of an X-ray source and searches for and extracts a type corresponding to the acquired source ID from source information of a storage device. In the case of an installation convenience preference type in which convenience in connection between a source controller and an electronic cassette is preferred, a detection signal from a detection pixel of an FPD of the electronic cassette is output from a detection signal I/F of the electronic cassette to a detection signal I/F of the source controller. In the case of an installation convenience non-preference type, an irradiation stop signal based on the comparison result of the integrated value of the detection signal from the detection pixel with an irradiation-stop threshold is output from an irradiation signal I/F of the electronic cassette to an irradiation signal I/F of the source controller.

  • Patent number: 9055922
    Abstract: When an AEC sensor is changed, the same AEC as before changing the AEC sensor is carried out without modifying an existing apparatus. A storage and search unit of a console acquires a source ID and searches for and extracts position information of a detection field of an old AEC sensor corresponding to the acquired source ID from source information of a storage device. An electronic cassette includes plural detection pixels as a new AEC sensor short-circuited to signal lines without passing through TFTs in the same imaging plane as pixels. A detection field selecting circuit of an AEC unit of the electronic cassette selects a detection signal from the detection pixel existing at the position of the detection field of the old AEC sensor among the detection signals of the plural detection pixels.

  • Patent number: 9042519
    Abstract: A compensation circuit 76 of an AEC unit 67 of an electronic cassette 13 defines the detection signal of a detection pixel 65 of the electronic cassette 13 as a detection signal corresponding to the detection signal of an old AEC sensor 25. The compensation circuit 76 performs compensation so as to exclude the influence on the detection signal due to a difference in the configuration of an intermediate member disposed between an X-ray source 10 and an FPD 35 of the electronic cassette 13 when the detection pixel 65 is used as an AEC sensor instead of the old AEC sensor 25. The detection signal is transmitted from a detection signal I/F 80 to a detection signal I/F 26 of a source control device 11 as it is (instantaneous value) or as an accumulated value obtained using an integration circuit 77.

  • Publication number: 20150139398
    Abstract: In capturing an image of a grid by an image detector, a measurement pixel that is not in the position of a specific point having a maximum or minimum value of an output signal is referred to as a first measurement pixel, and a measurement pixel that is in the position of the specific point is referred to as a second measurement pixel. The disposition of the first and second measurement pixels are determined so as to satisfy the following condition: fG/fN?odd number, wherein fG is a grid frequency and fN is a Nyquist frequency of pixels; and in shifting the grid C times by one pixel, the number of the first measurement pixels is larger than that of the second measurement pixels at any time in the range of a cycle C of a repetition pattern appearing in the image.

  • Publication number: 20150131784
    Abstract: An image detector is disposed behind a grid. The image detector has normal pixels and measurement pixels. Out of a group of measurement pixels based on which an average value of dose measurement signals is calculated, a [C/D] number of measurement pixels are disposed or chosen in a cycle Z=(R×C)±D. Wherein, C represents a cycle of a repetition pattern appearing in an arrangement direction of X-ray transparent layers and X-ray absorbing layers in an X-ray image of the grid, and is represented in units of the number of pixels. R represents a natural number of 0 or more. D represents an integer less than the cycle C. [C/D] represents a maximum integer equal to or less than C/D. Provided that at least the [C/D] number of measurement pixels are shifted C occasions by one pixel, if D=1, the average value of the dose measurement signals is invariable without any variations.

  • Patent number: 8967861
    Abstract: A radiographic image detection apparatus includes a detection panel and a housing for containing the detection panel. The housing consists of a front surface member, a back surface member, and a carbon plate attached so as to cover an opening formed in the front surface member. The carbon plate is faced to the detection panel. To the carbon plate is adhered a transparent sheet having transmissivity to radiation and visible light. A first index and a second index are printed on an inner surface of the transparent sheet. The first index is a square-frame shaped index showing a radiation detection range of the detection panel. The second index is a cross-shaped index showing a center position of the radiation detection range. The first and second indices are formed of nonmetallic UV curable ink having no radiation shielding properties.

  • Publication number: 20150036802
    Abstract: In a detection panel, plural pixels which receive X-ray and accumulate electric charge and plural measuring pixels which detect X-ray dose are provided on an imaging surface. The plural measuring pixels are arranged periodically with an interval. In a position facing to the imaging surface, there is a grid where X-ray absorbing sections and X-ray transmitting sections are arranged in a periodic alternating manner in a first direction. Since the arrangement period of the measuring pixels in the first direction is different from a fluctuation period of grid detection signals obtained when the grid is photographed by the detection panel, output values of the plurality of measuring pixels disperse and a fluctuation range of average values is suppressed.
