Research Abstract

It is very important to evaluate the radiation dose, as the newly development CBCTs have large radiation field. There are many studies for physical characteristics of the CBCT、. however, the evaluation of radiation dose and that of image quality evaluation have not been performed. The purpose of this research is to develop a new method to evaluate radiation dose and image quality.
