PROBLEM TO BE SOLVED: To provide a radiographic apparatus in which an object can be placed properly and a clear phase contrast image can be obtained.SOLUTION: A radiographic apparatus 1 is provided with: a radiation-irradiating unit 11; a first grating 31, which has a periodic structure obtained by the arrangement of multiple linear objects 31b and which forms a radiation image comprising a periodic intensity distribution as a result of radiation passing therethrough; a detecting unit 14, which contains a radiographic image detector 30 and acquires radiographic image data by detecting the radiation image that has been irradiated from the radiation-irradiating unit, passed through the first grating and the object, and been modulated by the periodic intensity distribution; and a guiding unit 70, which guides the placement of the object in relation to the orientation of the group of linear objects of the first grating. |
