The ML-EM algorithm in continuum: sparse measure solutions

Camille Pouchol, Olivier Verdier

Linear inverse problems Aμ=δ with Poisson noise and non-negative unknown μ≥0 are ubiquitous in applications, for instance in Positron Emission Tomography (PET) in medical…

Spatiotemporal PET reconstruction using ML-EM with learned diffeomorphic deformation

Ozan Öktem, Camille Pouchol, Olivier Verdier

Patient movement in emission tomography deteriorates reconstruction quality because of motion blur. Gating the data improves the situation somewhat: each gate contains a movement p…
