Abstract
An object of this invention is to provide a tomography method and a tomography system capable of tomographic imaging targeted uniquely to the test object among subjects under test. The method involves performing a process of generating projection data about the region of interest by selecting one reference projection data set from a plurality of projection data generated in a tomography process using a plurality of X-ray energy levels and by subtracting from the reference projection data set the product of an attenuation coefficient and the transmission length of the material configuring any region other than the region of interest detected by detector elements of detectors, and performing an image reconstruction computing process to generate a tomographic or stereoscopic image of the region of interest through image reconstruction based on the projection data about the region of interest generated in the projection data generating process.
