a position detecting unit for detecting respective positions of said radiation source and said radiation conversion panel;
and
a determining unit for determining whether said radiation source and said radiation conversion panel are placed in head-on
facing relation to each other based on the positions of said radiation source and said radiation conversion panel which are
detected by said position detecting unit;
