Abstract

Highly penetrating cosmic ray muons constantly shower the earth at a rate of about 1 muon per cm² per minute. We have developed a technique which exploits the multiple Coulomb scattering of these particles to perform non-destructive inspection without the use of artificial radiation. In this paper we present a Maximum Likelihood / Expectation Maximization (ML/EM) tomographic reconstruction algorithm designed for the technique.
