1. A breast imaging device for rotating a radiation detection unit configured to detect radiation irradiated from a radiation generation unit configured to generate the radiation with the radiation detection unit and the radiation generation unit facing each other, comprising:
a ray sum image generation unit configured to generate a ray sum image based on an addition value of at least one pixel value in a visual line direction from volume data reconstructed from a projection image output from the radiation detection unit;
a maximum intensity projection image generation unit configured to generate a maximum intensity projection image based on a maximum pixel value in the visual line direction from the volume data;
a synthesizing unit configured to synthesize the ray sum image and the maximum intensity projection image;
a first parameter setting unit configured to set a parameter regarding the ray sum image for the ray sum image generation unit; and
a second parameter setting unit configured to set a parameter regarding the maximum intensity projection image for the maximum intensity projection image generation unit, wherein
the first parameter setting unit sets the parameter regarding the ray sum image such that a tumor tissue is visualized in the ray sum image, and
the second parameter setting unit sets the parameter regarding the maximum intensity projection image such that a calcified tissue is visualized in the maximum intensity projection image.
