This Digital Subtraction Angiography (DSA) Phantom follows the recommendation in Report No. 15 by the AAPM (American Association of Physicists in Medicine) - Digital Radiology / Fluorography Task Group of the Diagnostic X-Ray Imaging Committee. Phantom is designed to evaluate digital functions of DSA systems and can be used to check: contrast range, resolution, linearity, uniformity, amplifier dynamic range,registration accuracy and subtraction effectiveness. Its modular construction allows setting up the desired test configuration in a very easy and accurate manner.
