  • Publication number: 20140211922
    Abstract: Upon input of a synchronization signal, which indicates a start of an X-ray emission, from a source control unit for controlling an X-ray source, an electronic cassette makes an FPD start an accumulation operation and measurement of an X-ray dose. The electronic cassette and a console command their communicators to stop communication of any signal other than a stop signal, which stops the X-ray emission from the X-ray source, during the accumulation operation of the FPD. As soon as the X-ray dose has reached a predetermined threshold value, the electronic cassette transmits the stop signal to the source control unit through the console. A delay in transmission of the stop signal due to communication congestion or signal collision does not occur, because the electronic cassette and the console stop the communication of the signal other than the stop signal.

  • Patent number: 8787528
    Abstract: A diagnostic device system has a weight-reduced rechargeable battery. When a portable radiographic apparatus and a portable X-ray source are carried to and used for imaging at a private home or a care home, the portable radiographic apparatus and the portable X-ray source are loaded on an automobile. When the charge amount of rechargeable batteries for operation housed in the portable radiographic apparatus or the portable X-ray source loaded on the automobile is low, or when there are plural destinations and the charge amount of the rechargeable batteries becomes low, a rechargeable battery for charging mounted on the automobile is used to charge the rechargeable batteries for operation while traveling. Because the rechargeable batteries for operation are charged while traveling, a large number of rechargeable batteries for operation does not need to be charged in advance, whereby the weight of the rechargeable batteries for operation can be reduced.

  • Publication number: 20140177798
    Abstract: A communication section having a relatively high communication speed is used for communicating a detection signal or an emission stop signal between a source control device and an electronic cassette. The detection signal is outputted from a detection pixel of the electronic cassette. The emission stop signal depends on a comparison result between an integrated value of the detection signal and an emission stop threshold value. On the other hand, a wireless communication section having a lower communication speed than that of the detection signal and the emission stop signal is used for communicating image data and the like between the electronic cassette and a console.

  • Patent number: 8737563
    Abstract: A radiation imaging system has a radiation generation device, an FPD cassette, and a console. The console judges whether or not the FPD cassette is in a good communication state repeatedly once every thirty seconds. Upon receiving a radiography order, the console changes repetition intervals from thirty seconds to three seconds, and keeps judging the communication state of the FPD cassette. The repeated judgment is continued until a shutter button is pressed. Upon the press of the shutter button, the radiation generation device emits radiation to carry out radiography.

  • Patent number: 8576087
    Abstract: A radiation imaging system includes a radiation imaging cassette and a console device. A communication mode between the cassette and the console device is switchable between a wired mode and a wireless mode. Due to shortage of a battery of the cassette, the communication mode is switched to the wired mode to start charging the battery and send image data from the cassette to the console device through a cable. The console device has first and second judging sections. The first judging section judges whether or not a charge level of the battery exceeds a predetermined threshold value. The second judging section judges whether or not radiography is in progress. If it is judged that the charge level of the battery exceeds the predetermined threshold value and the radiography is not in progress, a window that indicates permission for switching to the wireless mode is displayed on a monitor.

  • Patent number: 8532261
    Abstract: A portable radiographic apparatus system reduces the number of types of spare rechargeable battery. A first rechargeable battery for operation of a portable radiographic apparatus has the same shape and characteristics as a second rechargeable battery for operation of a portable X-ray source. The first rechargeable battery and the second rechargeable battery are interchangeable. When, in order capture images during a visit to an individual's home or a visit to a nursing facility, the portable radiographic apparatus and the portable X-ray source are taken to the visit destination, spare rechargeable batteries must be taken in case of trouble with the rechargeable batteries. Because the first rechargeable battery and the second rechargeable battery are interchangeable, by bringing either the first rechargeable battery or the second rechargeable battery, trouble can be addressed if it arises. In this way, the number of types of spare rechargeable battery can be reduced.

  • Publication number: 20130058454
    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.
