MiTiV (Méthodes Inverses de Traitement en Imagerie du Vivant) is a project funded by the French ANR (Agence Nationale de la Recherche, N° ANR-09-EMER-008). The objectives are to exploit the inverse approach for image reconstruction in bio-medical imaging and astronomy. The project includes the development of tools that can be used by non-specialists for improving image quality for image restoration in coronarography and 3-D microscopy.

The deconvolution result show a strong improvement both in term of resolution and signal to noise ratio.

Dynamic CT mechanical phantom, Elekta Synergy cone-beam CT.
Dynamic reconstructions of the 2D central slice of a mechanical phantom of a thorax, from data acquired with a Elekta Synergy cone-beam CT, at the Centre Léon Bérard, Lyon, France. Only the data corresponding to the central slice was taken, which gives a 2D truncated sinogram in fan beam geometry. About 600 projections were acquired on 360°.
