摘要： Provided are a radiographic imaging apparatus and a method of controlling the same. The radiographic imaging apparatus includes a radiographic source configured to emit radiographic rays in a discontinuous eigen energy spectrum, a radiographic detector configured to receive the radiographic rays, convert the received radiographic rays into electrical signals, and count the number of photons having energy that exceeds a threshold energy, and a controller configured to adjust the threshold energy by comparing an energy spectrum of the detected radiographic rays with the eigen energy spectrum of the emitted radiographic rays from the radiographic source.
