    Abstract: A position detection unit is disposed at an exposure position that is included in a camera image and a field of view of a camera and outputs a position signal indicating the position of a part of a peripheral portion of an electronic cassette. The calculation unit calculates an in-image cassette position which is the position of the electronic cassette in the camera image, on the basis of the position, direction, and size of the position detection unit in the camera image and the position signal. A composite image generation unit generates a composite image of the camera image and a cassette frame indicating the in-image cassette position. A display controller displays the composite image on a touch panel.

  • Patent number: 9513379
    Abstract: A radiographic image capture device includes a radiation detector, an application section and a controller. The radiation detector includes plural detection pixels that detect a radiation application state and plural imaging pixels that capture a radiographic image. The application section applies a bias voltage to each of the plural detection pixels and to each of the plural imaging pixels. The controller effects control such that, if the radiation application amount detected by the detection pixels is equal to or greater than a first threshold value during a first state in which the bias voltage is applied to the plural detection pixels, the application section is caused to transition to a second state in which the bias voltage applied to the detection pixels is reduced.

  • Patent number: 9492137
    Abstract: A portable X-ray imaging apparatus includes an electronic cassette for imaging of an X-ray image and transmitting the X-ray image wirelessly. An image receiving unit communicates with the electronic cassette and receives the X-ray image wirelessly. A passive monitoring device receives ambient electromagnetic waves to measure communication environment by passive monitoring. An active monitoring device performs data communication between the electronic cassette and the image receiving unit to measure the communication environment by active monitoring. Furthermore, an evaluation device detects a cause of a communication failure by considering a result of the passive monitoring and a result of the active monitoring. The evaluation device detects that the cause of the communication failure is a blocking object blocking radio waves or a relative position between the electronic cassette and the image receiving unit according to the results of the passive and active monitoring.

  • Patent number: 9322928
    Abstract: A determination section of an FPD checks external information against a determination table and determines whether detection of a rise of X-ray pulses is allowed based on an output voltage from a short-circuited pixel. The FPD detects X-ray images. The external information is transmitted from an imaging control device. The X-ray pulses are sequentially generated by an X-ray generating apparatus. A controller selects a pulse irradiation mode in a case where the detection of the rise of the X-ray pulse is allowed. If not, a successive irradiation mode is selected. In the pulse irradiation mode, the rise and the fall of the X-ray pulse are detected and timing of storage operation is synchronized with the detected timing of the rise. In the successive irradiation mode, the storage operation is performed at predetermined time intervals without the detection of the rise and the fall of the X-ray pulse.
