Paper Abstract

The ID19 3D Synchrotron Radiation Computed MicroTomography (SR (mu) CT) developed at ESRF in Grenoble, uses a 2D detector to record projection images of a sample. If the sample is not completely embedded in the x-ray beam at every angle, the local reconstruction problem may not be solved using the conventional filtered backprojection algorithm. The use of wavelet based algorithms may be a valuable solution for local reconstruction. In this paper, we present a new multiresolution tomographic reconstruction algorithm based on non separable wavelets. The algorithm allows to reconstruct the approximation and detail of an image from its parallel projections. Its application for local tomography is illustrated both from simulated and physical data.
