Abstract: An X-ray imaging system includes an X-ray imaging apparatus and an access controller, which controls communication access of the X-ray imaging apparatus having an electronic cassette for forming an X-ray image and wirelessly transmitting the X-ray image. Before the electronic cassette starts transmitting the X-ray image, a priority request signal for priority of the first radio communication channel to the electronic cassette over a portable terminal device of radio communication is received. Upon receiving the priority request signal, presence of the portable terminal device is checked, in which a radio communication channel of overlap of frequency on the first radio communication channel is used. In presence of the portable terminal device with the overlap, the portable terminal device is regulated in communication regulation while the electronic cassette transmits the X-ray image. Also, the X-ray imaging apparatus is communicable by use of a communication network in wireless communication connection.

Abstract: A radiographic imaging apparatus includes an electronic cassette and a console device for radio communication with the electronic cassette. The electronic cassette includes a transmitter for transmitting a beacon for the radio communication. A regulation unit regulates beaconing of the beacon in a predetermined specific state among plural operational states. The console device includes a receiver for receiving the beacon. A communication failure detector checks whether a communication failure has occurred in the radio communication according to a receiving state of the beacon in the receiver. A display panel or speaker generates alert notification to notify the communication failure assuming that the communication failure detector judges that the communication failure has occurred. An operational state detector checks whether the electronic cassette is in the specific state. An alert manager avoids generation of the alert notification while the operational state detector judges that the electronic cassette is in the specific state.

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.
