Published in 2020 at "Journal of Applied Clinical Medical Physics"

DOI: 10.1002/acm2.12821

Abstract: Abstract The circular‐edge technique using a low‐contrast cylindrical object is commonly used to measure the modulation transfer functions (MTFs) in computed tomography (CT) images reconstructed with iterative reconstruction (IR) algorithms. This method generally entails averaging… read more here.
