PROBLEM TO BE SOLVED: To improve the reliability of the motion control of radiography applying radio communication and the safety, or the like of a camera operator and a subject by preventing selection of a wrong radiation detector when radio communication is applied to a radiographic system and by reducing the number of system operation steps in performing the radiography.SOLUTION: A setting communication machine 11 is disposed in a radiographic cradle 1, so that the radiographic cradle 1 transmits setting information to the radiation detector 2 and a radiographic apparatus 4 when the radiation detector 2 is disposed in a radiation detector mounting part 3 of the radiography cradle 1 by the camera operator. The radiographic apparatus 4 receives the setting information transmitted from the radiographic cradle 1 by a setting communication part 42, and starts the radiography process by the radiation detector 2 based on the received setting information.COPYRIGHT: (C)2011,JPO&INPIT【課題】放射線撮影システムに無線通信が適用されたときの放射線検出器の取り違い防止と、放射線撮影を行う際のシステム操作数の減少を行うことにより、無線通信を適用した放射線撮影の動作制御の確実性、撮影技師・被写体の安全性等を向上させる。【解決手段】撮影架台1に設定通信機11を配置することで、撮影技師が撮影架台1の放射線検出器装着部3に放射線検出器2を配置した際に、撮影架台1は放射線検出器2と放射線撮影装置4に設定情報を送信する。放射線撮影装置4は設定通信部42より撮影架台1が送信した設定情報を受信し、放射線撮影装置4は受信した設定情報を基に放射線検出器2により放射線撮影処理を開始する。【選択図】図2
