Statistical reconstruction

Tomographic reconstruction for 3-photon imaging based on hybrid PET/Compton cameras

PhD thesis on statistical tomographic reconstruction for 3-photon imaging and hybrid PET/Compton cameras, with application to the XEMIS2 system.

CASToR - XEMIS2

Extension of the CASToR framework dedicated to multi-class reconstruction of medical images and Fisher information matrix estimation for $3\gamma$ PET/Compton imaging from continuous photon detections.

NEMA Script

Bash scripts for generating NEMA NU 4 digital phantoms (sections 3 and 6) and associated masks, with outputs compatible with CASToR and POLLUX workflows.

Reconstruction multiclasse pour l'imagerie TEP 3-photons

This contribution addresses the problem of image reconstruction of radioactivity distribution for which the available information arises from several classes of data, each associated with a specific combination of detections

Multi-class maximum likelihood expectation-maximization list-mode image reconstruction, an application to three-gamma imaging

Our contribution focuses at improving the image reconstruction process for specific Compton imaging systems able to detect multiple classes of events, in the field of nuclear imaging.
