• As a reconstruction method earlier than CT, tomosynthesis has its characteristic. This paper first analyzes principles of tomosynthesis, through transformation of equation set of tomosynthesis, which describes relation between sectional image and projection image, and we have proved that tomosynthesis is the same as Algebraic Reconstruction Techniques essentially. Reconstruction of tomosynthesis is indeed the reconstruction of Algebraic Reconstruction Techniques which under limited angle. We may regard all directive projection information as constitution of two limited angle projection information. Finally we reconstruct sectional image by using conception of "row" in tomosynthesis. And computer simulation has proved our conclusion to be correct.
