RADIOGRAPHIC IMAGING SYSTEM AND ACCESS CONTROLLER FOR COMMUNICATION ACCESS

摘要

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.

主权项

1. A radiographic imaging system including a radiographic imaging apparatus having an electronic cassette for forming a radiation image and wirelessly transmitting said radiation image, and an access controller for controlling communication access of said radiographic imaging apparatus, said radiographic imaging system comprising:
said access controller including: a storage medium for storing frequency information of a frequency of a first radio communication channel used by said electronic cassette for transmitting said radiation image, and of a frequency of a second radio communication channel used by a communication device different from said radiographic imaging apparatus and communicable wirelessly; a command receiver for receiving a priority request signal for priority of said first radio communication channel to said electronic cassette over said communication device before said electronic cassette starts transmitting said radiation image; an overlap detector for referring to said storage medium upon receiving said priority request signal, and checking presence of said communication device in which a radio communication channel of overlap of frequency on said first radio communication channel is used; a communication limiter for operating in presence of said communication device with said overlap, and regulating said communication device in communication regulation while said electronic cassette transmits said radiation image.
