Referee report. For: Low dose protocol for high resolution CT thorax: influence of matrix size and tube voltage on image quality and radiation dose [version 1; peer review: 1 approved]
High-resolution CT (HRCT) thorax has increase demand due to its advantage in diagnosing chronic respiratory diseases. The feasibility of matrix size with different tube voltage in the HRCT protocol of thorax is unknown. Therefore, this study aimed to compare the effect of matrix sizes and tube voltage on image quality and radiation dose on adult HRCT thorax. Methods: A Phantom experiment was performed, followed by a patient scan. For phantom and patient scan, a total of six protocols with twodoi:10.5256/f1000research.122637.r130052 fatcat:kobnhk67sbdphfeh5zxyfl3xly
