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.

Abstract: A portable X-ray imaging apparatus has an electronic cassette and a console capable of receiving an imaging order. The console has a wireless communication section, a trigger signal obtaining section, a connection determining section, a switching section, and a delivery requesting section. The wireless communication section receives radio waves and connects itself to an access point (AP). The trigger signal obtaining section obtains a trigger signal while the mobile radiography unit stands still. At the time of obtaining the trigger signal, the connection determining section determines one of the APs as an appropriate AP based on field intensity. The switching section switches the connection to the appropriate AP. Then, the delivery requesting section transmits a delivery request for the imaging order.
