X-ray image processing apparatus and method

A radiation image processing apparatus that performs image processing on a radiation image which is acquired by radiographing radiation that transmits through a subject, the radiation image processing apparatus comprising:

• a first setting unit configured to set an image processing parameter corresponding to each of a plurality of sites of the subject;
• a selection unit configured to select a site based on a degree of similarity between a radiographed site of the subject and at least one of the plurality of sites;
• and
• a second setting unit configured to set an image processing parameter corresponding to the radiographed site based on the site selected by the selection unit.

A computer-readable medium storing a computer program of instructions which cause a computer to perform a method comprising:

• determining, based on discrete site information, continuous site information which is obtained by radiographing a moving image;
• extracting from the discrete site information image construction information, image processing method information, and X-ray exposure control method information;
• computing processing information about a site located between positions represented by the discrete site information using the extracted image construction information, the extracted image processing method information, and the X-ray exposure control method information;
• and
• performing image processing and X-ray exposure based on the computed processing information.
