ABSTRACT:
In order to obtain a tomographic image close to a stationary image using opposite view data, a radiation tomography method and apparatus are provided for measuring projection data representing a subject by radiation beams in a plurality of view directions around the subject; calculating estimated projection data for each of the plurality of view directions by performing a weighting calculation on data elements of the projection data generated by radiations which transmit through the same path in opposite directions so that a desired time phase for the subject is centrally weighted; and producing a tomographic image of the subject based on the estimated projection data.
