Abstract

It is well known that the reconstruction problem in fluorescence diffuse optical tomography is badly conditioned and requires the knowledge of medium optical properties. Its principle is to measure the fluorescence light emerging at different positions of the surface when the biological medium is excited with point sources. In this paper, we evaluate the influence of the medium optical properties and the noise on the fluorescence reconstruction, and we introduce a new regularized fluorescence reconstruction method using an a priori on contours. The fluorescence reconstruction improvement is studied when using this method.
