    The aim of this study was to determine the Computed Tomography (CT) number and image appearance of commonly used additive manufacturing (AM) materials and compare them to CT numbers of human tissues. AM samples, measuring 40 x 20 x 10 mm, were manufactured and scanned using a Philips Brilliance 10 slice system. The CT number was measured and samples visually assessed. Many AM materials have a mean CT number that is very similar to human tissues, for example, bone, blood and water. In addition to this, fused deposition modelling, stereolithography and selective laser sintering generated samples that gave a uniform signal on CT images and 3D printed materials demonstrated a variation in internal structure. AM materials may be suitable for the development of anatomically accurate phantoms for image quality and radiation dose tests.
