| Outline of Final Research Achievements |
In the conventional X-ray CT, scattered X-ray has been usually removed because it causes harm to the reconstruction of the tomographic image. However, together with energy (spectrum) information, scattered radiation also has information on the irradiated object.
In the reconstruction method based on the principle that the projection data of the model in the computer and the actual projection data are in agreement with each other, it is expected that improvement of reconstruction accuracy can be expected by measuring lateral and backward scattering is there.
In this research, by simplifying the problem, we obtained a strong theoretical result for this. Based on this, there is a possibility of constructing a device with less exposure.
