摘要
A device for determining the radiation absorption distribution in a three-dimensional examination zone which is irradiated from different positions which are situated in one plane and in which radiation sources are present. The device comprises two detector arrays consisting of separate, adjacently arranged detectors, which are situated at a distance from and parallel to each other in a first plane and in a second plane. The device further comprises radiation sources which are situated between the two extreme planes and which are arranged to be rotate around an axis of rotation which extends transversely of said planes. The radiation sources are line-shaped and are arranged parallel to the axis of rotation and diametrically with respect to the axis of rotation opposite a detector array.
