<P>PROBLEM TO BE SOLVED: To provide a radiation tomography apparatus capable of acquiring a clear image without being influenced by the body motion of a test object even in a state that various apparatuses are attached to the test object as to a radiation tomography apparatus for mapping a generation position of an annihilation γ-ray pair. <P>SOLUTION: The radiation tomography apparatus includes a radioactive probe holder 6 attached to the test body. A position information correction part 22 recognizes a relative position of the test body to a detector ring 12 when an annihilation γ-ray pair is detected and corrects position information indicating the generation position of the annihilation γ-ray pair. Consequently, a clear image can be obtained without being influenced by the body motion of the test object. Since radiant rays are used in this invention, the body motion of the test body can be surely monitored even when the probe holder 6 cannot be observed by various apparatuses attached to the test body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
