A gamma-ray image acquisition device () acquires the direction and energy of a target scattered gamma-ray generated by Compton scattering of an incident gamma-ray and acquires the direction and energy of a recoil electron. These pieces of information are used to acquire the incident direction and energy of the incident gamma-ray. The gamma-ray image acquisition device () acquires a two-dimensional image by imaging spectroscopy based on the incident directions and energies of a plurality of incident gamma-rays, the two-dimensional image being an image in which each pixel corresponding to each incident direction includes energy distribution information. In the two-dimensional image, the area and the solid angle of an imaging range are proportional to each other. This enables acquiring the distribution of gamma-ray intensities without depending on distance and thereby acquiring an image that indicates more useful information than conventional images.
