In order to provide a simple and easy tomographic image analysis device capable of obtaining stable results, this tomographic image analysis device (1) is provided with an image standardization unit (12) for deforming a PET image (D) prior to a tomographic image analysis such that the contour of the brain of a subject in the PET image (D) becomes a brain contour indicated by standard data (S). By performing such a deformation operation prior to the analysis, the need for acquiring an MRI image as in the prior art is eliminated, and the burden on the subject can be reduced. According to the present invention, the analysis time can be reduced. Further, according to the present invention, the temporal change of radioactive medicine distribution in a corresponding region on a standardized PET image (E), which corresponds to a region of interest on the standard image (S), is analyzed. By doing so, the analysis result can be stabilized.
