Abstract

The generation of contrast signals through digital mask-mode subtraction is studied with an emphasis on the Low contrast situations. The effects of beam hardening, radiation scattering, and veiling glare are discussed. The linearity between the contrast signal and the iodine concentration is tested at contrast levels from 3.7 mg/cm³ to 370 mg/cm³ of iodine in a plastic tube of 2.7 urn in diameter. A xenon perfusion study of a canine brain is presented.
