PROBLEM TO BE SOLVED: To easily identify the displacement when radiographic equipment is positioned to a subject. SOLUTION: Positions of difference in level caused by projections 31a and 31b disposed at four corners of a casing lid are located on extension lines of the sides of the effective radiographic area A of a detection panel 25 projected on the casing lid, and a target radiographic area B is demarcated by the projections 31a and 31b. The difference in level of the projections 31a and 31b is formed in such a way as recognizable by an operator with fingertips, and accordingly, when the X-ray equipment 21 is positioned to the subject S by the operator, the operator inserts a hand between the subject S and the X-ray equipment 21 and confirms the difference in level of the projections 31a and 31b with fingertips. In this way, the relative displacement Xe of the effective radiographic area A of the detection panel 25 from the subject S can be eliminated. COPYRIGHT: (C)2007,JPO&INPIT
