2. The X-ray imaging apparatus according to claim 1 , wherein each of the first X-ray source and the second X-ray source is spaced by a predetermined distance apart from a central axis of the X-ray generator.
3. The X-ray imaging apparatus according to claim 1 , wherein one of the first X-ray source and the second X-ray source is disposed on a central axis of the X-ray generator, and the other one of the first X-ray source and the second X-ray source is disposed at an edge of the X-ray generator.
4. The X-ray imaging apparatus according to claim 1 , wherein the controller is further configured to adjust a baseline distance between the first X-ray source and the second X-ray source based on the translation command which is received via the input device.
5. The X-ray imaging apparatus according to claim 4 , wherein the controller is further configured to adjust the baseline distance to within a range of between 5 centimeters and 10 centimeters.
6. The X-ray imaging apparatus according to claim 1 , wherein the controller is further configured to drive at least one from among the first X-ray source and the second X-ray source based on the radiography mode selection command which is received via the input device.
7. The X-ray imaging apparatus according to claim 1 , wherein the controller is further configured to rotate the X-ray generator and the X-ray detector based on the rotation command which is received via the input device.
8. The X-ray imaging apparatus according to claim 1 , further comprising a display device configured to display the stereoscopic image of the object.
9. An X-ray imaging apparatus comprising:
an X-ray generator including a first X-ray source configured to irradiate a first X-ray onto an object, and a second X-ray source which is spaced apart from the first X-ray source and configured to irradiate a second X-ray onto the object;
an X-ray detector configured to detect the first X-ray which has been transmitted through the object and the second X-ray which has been transmitted through the object; and
an image processor configured to produce a first X-ray image of the object based on the detected first X-ray, to produce a second X-ray image of the object based on the detected second X-ray, and to produce a stereoscopic image of the object based on the first X-ray image and the second X-ray image,
wherein a dosage of the second X-ray is less than a dosage of the first X-ray.
10. The X-ray imaging apparatus according to claim 9 , wherein the image processor is further configured to cause a picture quality of the first X-ray image to be substantially identical to a picture quality of the second X-ray image.
11. A control method which is executable by using an X-ray imaging apparatus, comprising:
irradiating a first X-ray onto an object;
detecting the first X-ray which has been transmitted through the object and using the detected first X-ray to produce a first X-ray image of the object;
irradiating a second X-ray onto the object at a location spaced by a predetermined distance apart from a location at which the first X-ray has been irradiated;
detecting the second X-ray which has been transmitted through the object and using the detected second X-ray to produce a second X-ray image of the object; and
producing a stereoscopic image of the object based on the first X-ray image and the at least one second X-ray image,
wherein a dosage of the second X-ray is less than a dosage of the first X-ray.
12. The control method according to claim 11 , before producing the stereoscopic image of the object, further comprising causing a picture quality of the first X-ray image to be substantially identical to a picture quality of the second X-ray image.
