In this study, the dose distribution in phantom in 320 detector row cone beam CT (CBCT) was analyzed in detail using EGS5. Our results show that maximum dose position is 18 mm depth from the phantom surface, and peak deposit energy is 11 % higher than the phantom surface dose. In the 320 detector row CBCT, peripheral position dose is underestimated using conventional weighted CTDI estimation method.
