1. Radiation tomography apparatus comprising:
a radiation source for emitting radiation; a radiation detecting device for detecting radiation; an image generation device for generating fluoroscopic images from detection signals of the radiation detecting device; a tomography image generation device for reconstructing a series of fluoroscopic images, thereby generating tomography images; a rotary device for rotating the radiation source; and a holder provided between the radiation source and the radiation detecting device that has two or more spaces for placing a subject, the holder including space discriminating members extending continuously and absorbing radiation for each of the spaces, and each of the space discriminating members extending toward a rotation axis of the radiation source and having a substantially columnar shape along the entire rotation axis of the radiation source, each space discriminating member being parallel to a corresponding space among the two or more spaces for placing subject, and each of the space discriminating members having a unique sectional shape when cut along a plane where an imaginary circle exists, the imaginary circle being a locus of rotation of the radiation source. |
