    摘要： A radiation image diagnosing system includes a tomosynthesis image capturing assembly for acquiring the data of a plurality of tomosynthetic sectional images. The acquired data of the tomosynthetic sectional images are processed to reconstruct a shift-and-add image by a shift-and-add processor. The acquired data of the tomosynthetic sectional images are also processed to reconstruct an FBP image by an FBP processor. The shift-and-add image and the FBP image are displayed parallel to each other on a display unit.
