Abstract

© 2022 IEEE.The Modulation Transfer Function (MTF) is a physical metric that explains the relationship between spatial resolution and contrast in the frequency domain for image quality evaluation. This study investigates the effect of the X-ray tube voltage (kVp) and radiation dose on MTF measurement in digital mammography. The MTF was determined for four radiation dose levels at two different kVp values according to the lEC 62220-1-2 standard. In conclusion, there was no significant difference between the results, and the MTF was determined to be independent of kVp and radiation dose.
