1. An apparatus for processing a radiograph, the apparatus comprising:

  • an inputter which outputs an image obtained by irradiating radioactive rays; and

    a line detector which performs a Hough transform on the image output from the inputter, senses at least one first edge line based on the Hough-transformed input image, performs a first Radon transform on a region in which the at least one first edge line is sensed, and obtains, as a first collimation line, an edge line from among the at least first one edge line based on a result of the first Radon transform.
