A medical imaging system creates three kinds of reconstructed images of a diagnosis target site in a subject through X-ray imaging of the diagnosis target site with a Talbot or Talbot-Lau imaging apparatus, the three kinds of reconstructed images being an absorption image, a differential phase image, and a small-angle scattering image. The medical imaging system includes: an input unit to receive an input of diagnosis target information for specifying the diagnosis target site, or the diagnosis target site and a disease to be diagnosed in the diagnosis target site； and a control unit to create a combined image of two kinds of reconstructed images among the three kinds of reconstructed images on the basis of the diagnosis target information input through the input unit, and to control a displaying unit to display the combined image.
