A Compton back‐scatter tomographical imaging model with minimal constraints was imposed as a potential contender for on‐line portable imaging. The line‐scan method based on scattered photon energy spectra can obtain a fairly high scan speed and spatial resolution. As such, radiation scattering imaging (or density reconstruction) is viewed as a nonlinear inverse problem. A multicriteria optimization‐based density reconstruction from computed compton scattering data illustrates the feasibility of this method. © 1999 John Wiley & Sons, Inc.
