Conventionally, as shown in FIG. 1, a tomographic image of a tomographic plane tilted at a predetermined angle θ 1 from a vertical line orthogonal to the body axis of a subject 2A is obtained using an X-ray tube and a detector in an X-ray CT apparatus. This can be easily obtained by tilting the gantry containing the device by a predetermined angle θ 1 from the vertical plane and performing tomography. On the other hand, as shown in Fig. 2, a tomographic image of a tomographic plane that intersects the body axis of the subject 2A by an angle θ 2 in the horizontal plane can only be obtained by tomography using a Surieux bed. .

The outline of this invention to achieve the above purpose is as follows:
The top plate has a narrow part that can be inserted into the imaging hole of the gantry of an X-ray CT device and a wide part that is located outside the imaging hole, and the body axis of the subject intersects with the center line of the imaging hole. The device is characterized in that a subject can be placed thereon.

小さくしておくのが望ましい。 As shown in FIGS. 4 and 5, the bed 10
is a stretcher 12 movable by wheels 11
A substrate 13 forming the upper surface plate of the stretcher 12 and a mat 14 placed on the substrate 13 to serve as a cushion are fixed to the substrate 13 via the mat 14 with bolts 15 and are When the subject is lying down, a large top plate 18 is provided, which has a narrow width part 16 where the subject's head is located and a wide width part 17 where the subject's waist and below are located. configured. Width l of the narrow width portion 16 of the large top plate 18
The narrow width part 16 can be inserted into the imaging hole in the gantry of the X-ray CT apparatus, and the body axis of the subject can be placed at a predetermined angle with respect to the center line of the large top plate 18 on the large top plate 18. It can be appropriately determined so that the subject's head can be placed on the large top plate 18 even if the ranges intersect. Further, the width L of the wide portion 17 of the large top plate 18 may be any width since there is no need to insert the wide portion 17 into the photographing hole, but the width L may be any width. Any material that is sufficient to hold at least the waist of the subject on the large top plate 18 when the body axis of the subject intersects within a predetermined angular range with respect to the center line of the large top plate 18 is sufficient. In addition, large top plate 1
The intermediate portion 19 located between the narrow width portion 16 and the wide width portion 17 in 8 has a width equal to that of the narrow width portion 16.
However, in order to minimize the generation of scattered X-rays during X-ray imaging, the width of the intermediate portion 19 may be made smaller than the width l of the narrow portion 16. is desirable.
