The visualization of blood vessels using noninvasive administration of contrast agents is clearly a desirable clinical goal. It opens up the opportunity for mass screening of vessel disease and the study of asymptomatic people who are at high risk. A number of approaches have been taken to view vessels noninvasively. In this paper we present some initial considerations of a system using measurements at three broad energy spectra.
