Thermo-acoustic tomography is a non-invasive medical imaging technique, constituting a precise and cheap alternative to X-imaging. The principle is to excite a body to reconstruct with a pulse inducing an inhomogeneous heating and therefore expansion

This article deals with the so called GVF (Gradient Vector Flow) introduced by C. Xu, J.L. Prince . We give existence and uniqueness results for the front propagation flow for boundary extraction that was initiated by Paragios, Mellina-Gottardo et Ra

This paper deals with a method of tomographic reconstruction of radially symmetric objects from a single radiograph, in order to study the behavior of shocked material. The usual tomographic reconstruction algorithms such as generalized inverse or fi

We present a regularization method to approach a solution of the pessimistic formulation of ill -posed bilevel problems . This allows to overcome the difficulty arising from the non uniqueness of the lower level problems solutions and responses. We p

28 pages, 14 references; The aim of this article is to provide and compare several numerical methods for the tomographic reconstruction of blurred and noised binary images, based on one single snapshot taken from an axially symmetric 3D object. This

In this paper, we focus on spatiotemporal regularization of Positron Emission Tomography (PET) reconstruction. Through a minimization problem defined on a dynamic variational framework we consider regularizers based on total variation priors adapted
