Guillaume Bal studied reconstruction from the <attenuated Radon transform> with full and partial measurements. His analysis distinguishes complete-data inversion from partial-angle reconstruction requiring additional conditions. The work uses a <Riemann-Hilbert problem> and operator decompositions, showing how incomplete ray measurements can still determine a source when attenuation and admissible functions are suitably controlled.<On the attenuated Radon transform with full and partial measurements by Guillaume Bal>[Abstract and Sections 2.1–2.2]{ref}
