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.

Abstract: An X-ray imaging apparatus includes an FPD and short-circuited pixels. The FPD has pixels arranged in arrays for detecting an X-ray image. The short-circuited pixels detect a radiation dose of X-rays in the FPD. The X-ray imaging apparatus is changed over between first and second operating modes. The first operating mode is selected in case of combining with an X-ray generating apparatus with communication compatibility, and performs an exposure control for controlling a total radiation dose according to a detection signal from the short-circuited pixels. The second operating mode is selected in case of combining with an X-ray generating apparatus with communication incompatibility, and performs control of start synchronization for synchronizing operation of the FPD with the emission start of X-rays according to a detection signal from the short-circuited pixels. Thus, control of the X-ray imaging apparatus is changed over appropriately.
