PURPOSE:To obtain a picture of high resolution and small in magnification even in the part of an object where radius of curvature is large by constituting the cassette nearly in an uncrooked state. CONSTITUTION:A baggy flexible container 11 that does not transmit light but transmits X-ray has an opening 11a for putting in and out an X-ray recording medium. To keep the opening 11a in a closed state, a holding belt 12 is provided with an end fixed to the opening, and a fastener 17 is attached to another end. Two plastic bars are provided on both sides of the X-ray recording body in the longitudinal direction of inside of the bag 11, and a contacting member 15 that contacts the object is provided outside. When this cassette is brought into contact with the object, the cassette becomes nearly in an uncrooked state and becomes La=La' instead of Lb<Lb'. Accordingly, it is highly effective when, obtaining a fluoroscopic picture of the part of object having a large radius of curvature such as a shoulder or a leg. |
