Abstract
An FPD has a detecting plane with detecting elements arranged in rows (u-axis) and columns (v-axis) extending in two intersecting axial directions. In time of primary scanning, the FPD is moved about a sectional axis to maintain the u-axis parallel to a body axis constantly. Consequently, in a reconstruction process, a set of projection points on the detecting plane of X rays having passed through lattice points in one row along the body axis A of an imaginary three-dimensional lattice, is parallel to the u-axis. It is therefore possible to derive all projection data that should be projected back to the lattice points in one row, only from detection signals acquired from the detecting elements in two lines having the set of projection points in between. Thus, the quantity of detection signals required for obtaining the projection data is reduced to perform the reconstruction process at high speed.
