| Outline of Final Research Achievements |
The simulated kV-CBCT agreed with measured within 10%. The effective energy and output of kV-CBCT were lower than those of diagnostic CT. The image uniformity and contrast-to-noise ratio were improved by our method. In contrast, spatial resolution was comparable between CT image applied with our method and that without our method. The image quality improvement was observed in human body, however, image quality reduced when same processing was applied to other patient. This was because the scattered radiation varied among patient. As for the problems to be solved from now on, it is essential to calculate scattered radiation for various patient and develop image filter which is available for various patient.
