PURPOSE:To improve a picture quality by superposing and displaying plural pictures reproduced from plural data obtained by moving finely a radiation detector. CONSTITUTION:A radiation detector 14 converts a radiation transmitting data from a body to be inspected 12 to an electric projecting data, and sends it out to a data collecting part 21 side. A reconstituted picture is stored in the first memory 25M1 through a CPU19 and a memory controller 24. Subsequently, basing on a driving command signal outputted by the CPU19, a detector driving control part 17 rotates the radiation detector 14 centering around a radiation focal position by a very small distance, for instance, by a 1/2 pitch size portion of each detecting element. A picture reconstituted from a radiation transmitting data obtained in this state is stored in a memory 25M2. The contents of each memory are converted to an optical image by display devices 271, 272, and projected to a screen 29 by optical systems 281, 282. The picture can be synthesized both on the memory and directly on one CRT. |
