Patent ID: 7664842

Claim:
A mobile radiography apparatus which is connected to a network to transmit/receive information to/from an information system which is connected to the network via a network cable and manages imaging order information, comprising: storing means for storing imaging order information; sensing means for sensing connection to the network; obtaining means for obtaining imaging order information; and X-ray detection means for obtaining digital image data by A/D converting an analog signal corresponding to intensity of X rays irradiated with irradiation condition on the basis of the imaging order information obtained by said obtain means, wherein said obtaining means issues imaging order information request to the information system and obtains the imaging order information corresponding to the imaging order information request from the information system through the network cable when it is determined as a result of sensing by said sensing means that the mobile radiography apparatus is connected to the network via the network cable, and obtains, from said storing means, imaging order information already stored in said storing means, which corresponds to the imaging order information request when it is determined as a result of sensing by said sensing means that the mobile radiography apparatus is not connected to the network via the network cable.
