Algorithms for joint activity–attenuation estimation from positron emission tomography scatter
BACKGROUND: Attenuation correction in positron emission tomography remains challenging in the absence of measured transmission data. Scattered emission data may contribute missing information, but quantitative scatter-to-attenuation (S2A) reconstruction needs to input the reconstructed activity imag...
