1. An X-ray imaging apparatus comprising:
an imaging body including an X-ray generation device and an X-ray sensing device, wherein the X-ray generating device and the X-ray sensing device are disposed to face each other, and configured to rotate about a rotation axis and acquire X-ray image data of an object including multiple sections;
an inspection table configured to move the object along a direction of the rotation axis between the X-ray generation device and the X-ray sensing device; and
a control circuit configured to:
capture a two-dimensional X-ray image of the object by controlling the imaging body;
acquire size information of the object based on the captured two-dimensional X-ray image of the object by measuring a length of each section of the object, wherein the length of each section is in a direction perpendicular to the rotation axis;
compute a moving speed of each section of the object with respect to rotation of the X-ray generation device and the X-ray sensing device based on the size information; and
capture a three-dimensional X-ray image by rotating the X-ray generation device and the X-ray sensing device and moving the inspection table with the object along a direction of the rotation axis based on the computed moving speed, wherein the moving speed of the inspection table is equal to the computed moving speed of each section of the object,
wherein the control circuit controls the moving speed of the inspection table with respect to a rotation speed of the X-ray generation device and the X-ray sensing device based on the computed moving speed of each section of the object while rotating the X-ray generation device and the X-ray sensing device and moving the inspection table for capturing the three-dimensional X-ray image.
