Abstract
This specification sets forth a cardiovascular phantom. The phantom is adapted for placement on a table between an X-Ray tube and a film camera. The phantom is formed from absorptive material comprising at least one layer of metallic material on a plastic board. The metallic material is formed in the shape of arterial vessels from a radiopaque material. The radiopaque material and phantom absorb the X-Rays in an analogous manner to a person's heart. The phantom provides an analog to allow adjustments for the X-Ray process used for cardiovascular analysis.
