Photon counting spectral CT (PCCT) can produce reconstructed attenuation maps
in different energy channels, reflecting energy properties of the scanned
object. Due to the limited photon numbers and the non-ideal detector response
of each energy channel, the reconstructed images usually contain much noise.
With the development of Deep Learning (DL) technique, different kinds of
DL-based models have been proposed for noise reduction. However, most of the
models require clean data set as the training labels, which are not always
available …
