Development of a deep learning based approach for multi-material decomposition in spectral CT: a proof of principle in silico study [PDF]

Scientific Reports
Conventional approaches to material decomposition in spectral CT face challenges related to precise algorithm calibration across imaged conditions and low signal quality caused by variable object size and reduced dose. In this proof-of-principle study, a

The effect of detailing the trabecular structure of bone phantoms on the assessment of the bone marrow dose from 89,90Sr

Радиационная гигиена, 2023
Today there exist two main approaches to developing computational phantoms for bone dosimetry. The first approach is based on a detailed description of the microarchitecture of the spongiosa filling the phantoms.
