JSolver Jointly Estimates Spectrum and Materials from Single-Energy CT Projections

A new arXiv paper presents JSolver, a method that performs multi-material decomposition using only single-energy CT projection data rather than requiring spectral CT scanners. Conventional decomposition approaches depend on spectral hardware and pre-measured spectra, which limits their availability in routine clinical settings. The work aims to make quantitative tissue-composition reconstruction feasible on standard single-energy systems.
