Abstract

A radiographic phantom is comprised of only two materials, a non-iodinated material composing the base and an iodinated material disposed in a channel simulating a blood vessel, thus providing for a resultant signal attributable only to the iodinated material when a radiographic subtraction process is conducted to test an apparatus for contrast sensitivity. The phantom is fabricated by forming the base of a plastic material, forming a channel in the base, and then filling in the channel with the same kind of plastic material but with minute amounts of iodine suspended uniformly therein.
