Material Decomposition of Energy Spectral CT by AUTOMAP

Energy spectrum CT can perform spectral imaging of objects. In the clinical and industrial fields, spectral images are often converted into a distribution image of the base material, ie, material decomposition. Traditional image domain material decomposition algorithms are often parsed point by point. This time we try to use the end-to-end AUTOMAP for fitting solution. AUTOMAP can perform image domain mapping and achieve certain effects on MRI image reconstruction, but our attempts at spectral CT material decomposition are not satisfactory.
