Abstract: The purpose of this study was to evaluate of usefulness for developed Computed Tomography (CT) phantom using Fused Deposition Modeling (FDM) 3-Dimensional (3D) printing technology with the same quality performance as American Association of Physicists in Medicine (AAPM) CT performance phantom. The phantom by using modeler program was the 180 mm in diameter, 50 mm height cylinder shape and constructed by making 30.6 mm in diameter round holes in the middle of inside of the cylinder and 4 spots on surrounding. To measure slice thickness and spatial resolution, we designed the cylinder shaped sub phantom to let it locate inside the round hole. This study was showed the CT phantom with the same quality performance as AAPM CT performance phantom using FDM 3D printing technology. The results of CT number of and noise were passing the criterion with 3.10 and 2.66 HU. The uniformity of CT number was a difference within ±5 HU between the centers. The study of spatial resolution was suited because the 1.0 mm thick wall of the cylinder with 5.0, 3.0 and 2.0 mm in grid size was distinguishable. In terms of the measuring slice thickness, the result was passing meeting the criterion; it came to 4.5 and 9.1 mm from 5.0 and 10.0 mm with deviation of ±1 mm. The comparing with AAPM CT performance phantom all categories were suitable for the AAPM CT evaluation criterion. We could expect that developed CT phantom was cheaper up to 80% than AAPM phantom so the small-medium size the hospitals can easily equip the high quality medical image technology devices.
