摘要： A transceiver of a radiation detecting cassette receives subject ID information from an RFID tag by way of wireless communications. An ID checker checks the subject ID information received by the transceiver against a plurality of subject ID information stored in an RFID memory. If the subject ID information received by the transceiver matches one of the subject ID information stored in the RFID memory, then the ID checker associates the matching subject ID information with a radiation dose that is stored in a dose storage unit and corresponds to the matching subject ID information.

摘要： A radiation image capturing method, a radiation image capturing system, and a radiation information system are provided. In the present invention, a console checks a cassette ID (specified cassette ID) sent from an RIS server as the cassette ID of a radiation detecting cassette that is planned to be used to capture a radiation image, and a cassette ID (actual cassette ID) that is read by the console from a radiation detecting cassette which is placed in an operating room or an image capturing room and which is to be actually used to capture a radiation image, with each other. Based on the result of the cassette ID check, the console determines whether to permit a radiation image to be captured or not.

摘要： An image capturing system includes a cassette having a radiation detector, an image memory, and a cassette controller, an image capturing apparatus, a display device, and a host computer. The cassette controller comprises a capacity value transmitter for transmitting a capacity value of the radiation image information to the host computer before transmission process, and an image transmitter for transmitting the radiation image information. The host computer comprises an indicator controller for controlling the display device to display an indicator representing the capacity value received from the cassette as the upper limit, and a bar controller for controlling the display device to display a bar moving toward the indicator and having a length corresponding to the received capacity value of the radiation image information while the radiation image information is being received.
