Radiographic imaging apparatus and method of controlling the same

A method of controlling a radiographic imaging apparatus, the method comprising:

• irradiating radiation to an object;
• detecting an intensity of the radiation passing through the object;
• dividing the object into one or more zones based on the intensity of the radiation;
• and
• controlling at least one of a movement speed of a loader configured to load the object and a range of radiation irradiation according to a change in the intensity of the radiation with respect to a zone of the object, when the change in the intensity of the radiation in the zone is greater than or equal to a zone threshold value.

A radiographic imaging apparatus, comprising:

• a radiographic imaging unit configured to obtain a radiographic image with respect to an object;
• and
• a processor configured to obtain attenuation information of the object based on the radiographic image and obtain one or more zones of the object by dividing the object based on the attenuation information,
• wherein the processor is configured to change at least one of a plurality of parameters for driving the radiographic imaging unit with respect to a zone of the object based on a change in the attenuation information in a corresponding zone,
• wherein the processor is further configured to:
• obtain a current tube current with respect to the one or more zones based on the attenuation information,
• when the change in the attenuation information in a first zone of the object is smaller than a threshold, determine a next tube current based on an average value of a current tube current with respect to the first zone of the object, and
• control the radiographic imaging unit to obtain a second radiographic image with respect to the first zone of the object using the next tube current.
