TOMOGRAPHIC METHOD

WIPO Patent Application WO/2011/030460

A1

A tomographic method is provided with a step wherein in reference to photographing timing correction data associating a plurality of gantry angles with a plurality of photographing timing correction amounts, an exposing timing is calculated on the basis of a photographing timing when an X-ray source supported by a rotating traveling gantry is disposed at a predetermined photographing angle and one of the photographing timing correction amounts which corresponds to a gantry angle at which the traveling gantry is disposed at the photographing timing, and a step wherein on the basis of X-ray images photographed with radiation from the X-ray source at the disposure timing, three-dimensional data relating to the subject of the X-ray images is calculated.  Even when the traveling gantry bends according to a gantry angle at which the traveling gantry is disposed, the tomographic method is capable of obtaining the X-ray images photographed with the radiation disposed precisely, thereby more precisely calculating the three-dimensional data thereof.
