Abstract

Background: There is a close relationship between the Radiation dose and the image quality; so that increasing the Radiation dose leads to an increase in the image quality. Methods: In this study, images of different thicknesses and filters were obtained by using Multidetector computed tomography (CT)-128 and Body mass measurement device-7 (BMMD-7) phantom scanner. The parameters of Radiation dose, noise, spatial, and contrast resolution were monitored by the observers as well. Findings: As the slice thickness increased, the amount of spatial resolution at different Radiation doses was not significantly different from that of the standard image. In addition, by changing the reconstruction filter, a similar behavior was observed for spatial resolution (P ˂ 0. 05). Conclusion: CT operators have the task of selecting the appropriate slice thickness and reconstruction filter for each medical application. Therefore, the Radiation dose can be reduced to a higher degree according to the image quality required for diagnosis
