Abstract
Method for making a test phantom and is disclosed which phantom is representative of human tissue containing variable concentrations of iodine to serve as a test device for assessing the performance of X-ray imaging systems such as digital subtraction angiographic apparatus. An iodine/polymer insert is embedded in a polyurethane composition which has X-ray adsorption characteristics similar to human body tissue. The incorporation of additional test details into geometrically fixed positions in the phantom allows accurate and reproduceable measurements of other performance parameters of digital X-ray imaging systems.
