Bioluminescence tomography is a recent biomedical imaging technique which allows to study
molecular and cellular activities in vivo. From a mathematical point of view it is an
ill-posed inverse source problem: the location and the intensity of a photon source inside an
organism have to be determined given the photon count on the organism's surface. To face the
ill-posedness of this problem a geometric regularization approach is introduced analyzed and
numerically verified in this book.
