Disclosed is an apparatus and method of acquiring images created by penetration of a radioactive ray. The apparatus includes a scintillator to generate a light signal in response to an irradiated radioactive ray, and to change an advancing direction of the generate 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.

1. A method of acquiring images created by penetration of a radioactive ray, the method comprising: receiving an irradiated radioactive ray;generating a light signal in response to the received radioactive ray;changing an advancing direction of the generated light signal;receiving the light signal whose advancing direction is changed to convert the received light signal into an electrical signal; andacquiring an image corresponding to the irradiated radioactive ray based on the converted electrical signal,wherein the light signal is generated and the advancing direction of the generated light signal is changed using a scintillator,wherein the scintillator includes a medium having a density different from a density of the surrounding air,wherein a side surface of the scintillator adjacent to a 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,wherein the light signal from the scintillator enters another medium different from the medium of the scintillator before entering the light receiving unit, andwherein converting the received light signal into the electrical signal and acquiring the image are performed using at least one processor. 2. The method of claim 1, wherein the changing of the advancing direction of the generated light signal includes changing the advancing direction of the generated light signal to a direction of the light receiving unit. 3. The method of claim 2, wherein the changing of the advancing direction of the generated light signal to the direction of the light receiving element includes changing the advancing direction to the direction of the light receiving element using the medium, a side surface of the medium adjacent to the light receiving element being formed into the concave shape. 4. The method of claim 1, wherein the scintillator is formed in a circular arc shape. 5. A method of acquiring images created by penetration of a radioactive ray, the method comprising: receiving an irradiated radioactive ray;generating a light signal in response to the received radioactive ray;changing an advancing direction of the generated light signal;receiving the light signal whose advancing direction is changed to convert the received light signal into an electrical signal; andacquiring an image corresponding to the irradiated radioactive ray based on the converted electrical signal,wherein the light signal is generated and the advancing direction of the generated light signal is changed using a scintillator,wherein the scintillator includes a first medium used to generate the light signal and a second medium used to change the advancing direction of the light signal, wherein the second medium changes the advancing direction of the light signal towards a direction of a light receiving unit based on a difference between a density of the first medium and a density of the second medium,wherein the light signal from the scintillator enters another medium different from the first medium and the second medium of the scintillator before entering the light receiving unit,wherein converting the received light signal into the electrical signal and acquiring the image are performed using at least one processor, andwherein a side surface of the first medium that contacts the second medium is formed into a concave shape, the concave shape being laterally asymmetrical with respect to a location of the light receiving unit. 6. The method of claim 5, wherein the scintillator is formed in a circular arc shape.
