Abstract:
1. An apparatus of acquiring images created by penetration of a radioactive ray, the apparatus comprising: a scintillator to generate a light signal in response to an irradiated radioactive ray, and to change an advancing direction of the light signal; a light receiving unit to receive the light signal whose advancing direction is changed; and a signal processing unit to convert the received light signal into an electrical signal, and acquire an image corresponding to the penetrated irradiated radioactive ray based on the converted electrical signal, wherein the scintillator includes a medium having a density different from a density of the surrounding air, wherein the light signal from the scintillator enters another medium different from the medium of the scintillator before entering the light receiving unit, wherein the another medium surrounds at least three sides of the light receiving unit, and wherein a side surface of the scintillator adjacent to the light receiving unit is formed into a concave shape, the concave shape being laterally asymmetrical with respect to a location of the light receiving unit.
