Transmission and joint activity/attenuation (MLAA) examples¶
Reconstruction of the attenuation image from transmission data using the exact Poisson model (no log-linearisation) with a strictly positive scatter background: MLTR and separable paraboloidal surrogates (SPS), their ordered-subset and SVRG variants, and penalised transmission reconstruction (MAPTR) with an edge-preserving prior. The final example extends these ideas to joint activity-and-attenuation estimation (MLAA) from a single TOF emission scan.
