Title:
GAMMA-RAY IMAGE ACQUISITION DEVICE AND GAMMA-RAY IMAGE ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/209059
Kind Code:
A1
Abstract:
A gamma-ray image acquisition device (1) acquires the direction and energy of subject scattered gamma rays scattered by Compton scattering of incident gamma rays, and acquires the direction and energy of recoil electrons. From this information, the incidence direction and energy of the incident gamma rays are acquired. By imaging spectroscopy based on the incidence direction and energy of a plurality of incident gamma rays, the gamma-ray image acquisition device (1) acquires a two-dimensional image in which each pixel corresponding to an incidence direction includes energy distribution information. In the two-dimensional image, the surface area thereof and the solid angle of the imaging range are proportional. A gamma ray intensity distribution can thereby be acquired without distance dependence, and an image indicating more useful information than that of the prior art can be obtained.
