Abstract
A test phantom and method of fabrication and use of the same is disclosed which phantom is representative of human tissue containing variable concentrations of iodine to serve as a test device in for assessing the performance of X-ray imaging systems such as digital subtraction angiographic apparatus. The method of fabrication provides the long-term stable incorporation of iodine into a tissue equivalent material which allows standardized testing and evaluation of X-ray imaging systems. 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.
