Abstract
The problem of reconstructing an image from its Radon transform projections is outlined and a minimum norm, optimal grid formulation is described. We develop the formalism necessary to apply fast adaptive composite grids (FAC) in this setting to obtain high resolution reconstructions in a selected region of the image. This avoids utilizing a fine grid on the entire image space, which leads to intractably large problems. Theoretical details and numerical results will be published in a future paper.
