1. A tomographic image capturing apparatus comprising: a radiation source for applying radiation to a subject at a plurality of different angles with respect to the subject; a radiation detector for detecting the radiation which has passed through the subject at each of the different angles and converting the detected radiation into image data; a tomographic image reconstructing unit for processing the image data into a reconstructed tomographic image; and an image capturing sequence setting unit for establishing an image capturing sequence of a tomosynthesis image capturing process and a simple image capturing process based on ordering information which represents the tomosynthesis image capturing process for acquiring the reconstructed tomographic image and the simple image capturing process for acquiring a simple captured image.
