Abstract:
A radiation tomography device comprising:an irradiating device for irradiating radiations to a subject to be examined; a radiation detector situated at a predetermined distance away from the irradiating device for detecting radiation picture images passing through the subject; a subject holding and rotating device situated between the irradiating device and radiation detector for holding and rotating the subject around a rotating axis, which intersects in the subject an irradiating axis from the irradiating device to the subject; a Laminographic angle variation device attached to at least one of the irradiating device and the subject holding and rotating device, said Laminographic angle variation device varying a Laminographic angle formed by the radiation irradiating axis and the rotating axis; a picture image processing device electrically connected to the radiation detector for obtaining a radiation fault picture image, said picture image processing device storing and calculating the radiation picture images sequentially obtained based on detected data outputted from the radiation detector as the subject is irradiated by the irradiating device and is rotated by the subject holding and rotating device; and a picture image display device for displaying the fault picture image obtained by the picture image processing device.
