PROBLEM TO BE SOLVED: To provide a technique advantageous for enabling one-shot elongated imaging such that in an effective region of a detector, a region of interest of a subject is not overlapped with a region reached by radiation from a radiation source after the radiation transmits through a frame region of another detector.SOLUTION: Provided is a control apparatus for a radiographic system which includes a radiation source for emitting radiation, a plurality of detectors for detecting radiation, and a support device for supporting the plurality of detectors. The control apparatus comprises: an acquisition unit for acquiring settings of a region of interest for a subject and a determination unit for determining whether or not the plurality of detectors can be arranged by the support device to satisfy a predetermined arrangement condition based on the region of interest.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】ある検出器の有効領域のうち、放射線源からの放射線が他の検出器の額縁領域を透過した後に到達する領域に被写体の関心領域が重ならないようにワンショット長尺撮影を行うために有利な技術を提供する。【解決手段】放射線を照射する放射線源と、放射線を検出する複数の検出器と、複数の検出器を支持する支持装置を有した放射線撮影システムの制御装置は、被写体に対する関心領域の設定を取得する取得部と、関心領域に基づく所定の配置条件を満たすように支持装置が複数の検出器を配置可能かを判定する判定部とを備える。【選択図】図3
