X-ray device and method for controlling x-ray irradiation area using the same

An X-ray imaging system comprising:

• an X-ray imaging device configured to acquire X-ray image data of an object by irradiating X-rays to an X-ray irradiation region of the object that is present in a direction in which the X-rays are irradiated;
• a camera disposed on the X-ray imaging device, and configured to acquire an image of the object;
• a display configured to:
• display the acquired image of the object, while displaying at least one icon corresponding to an X-ray imaging part of the object;
• and
• receive a selection of the displayed at least one icon,
• wherein the X-ray imaging device is further configured, based on the selection of the displayed at least one icon being received, display information for guiding an X-ray imaging of the X-ray imaging part.

A method of controlling an X-ray irradiation region, the method comprising:

• acquiring X-ray image data of an object by irradiating X-rays to the X-ray irradiation region of the object;
• acquiring an image of the object;
• receiving, by an input member, an input to adjust a size of the X-ray irradiation region;
• adjusting the size of the X-ray irradiation region, based on the received input;
• and
• displaying the acquired image in which the X-ray irradiation region having the adjusted size is indicated, while displaying a list of X-ray imaging parts of the object.
