Estimation of presampling modulation transfer function in synchrotron radiation microtomography

1 code implementation8 Sep 2016 Ryuta Mizutani, Keisuke Taguchi, Akihisa Takeuchi, Kentaro Uesugi, Yoshio Suzuki

The spatial resolution achieved by recent synchrotron radiation microtomographs should be estimated from the modulation transfer function (MTF) on the micrometer scale.
