Claim 4:
5. A radiography system comprising:
a radiation source that generates radiation;
a plurality of types of filters that change energy of the radiation generated by the radiation source; and
a filter switching mechanism that, in a case in which a radiography apparatus irradiates an object with the radiation emitted from the radiation source at a plurality of irradiation positions having different irradiation angles and captures a plurality of radiographic images of the object obtained by the irradiation with the radiation having different energy levels at each of the irradiation positions, switches the plurality of types of filters at each of the irradiation positions and switches a last filter used at an n-th irradiation position to an initial filter used at an (n+1)-th irradiation position.
