| Outline of Final Research Achievements |
I have developed a novel reconstruction algorithm for computed tomography using kV and MV X-rays, which are commonly used in the diagnostic and treatment beams, respectively. This study has improved the image quality by considering scattering X-ray, periodic and non-periodic anatomy motions, and restricted field imaging for treatment, as well as the dual energy CT reconstruction, and thus, contributes to the development of both systems of target verification and dose calculation.
