Emission tomography reconstruction algorithms (listmode data)¶
The same families of algorithms as the sinogram gallery, but operating directly on listmode (event-by-event) data through the listmode projector: listmode MLEM / OSEM / SVRG, stochastic-gradient variants, and listmode SPDHG. Listmode is the natural choice for sparse, high-resolution (e.g. TOF) data.
