The attenuation values polycarbonate material was evaluated using the XCom database. The results were compared with the attenuation values of the human thyroid published by the International Commission on Radiation Units and Measurements-ICRU no. 44. The adult thyroid was designed from scratch as a 3D thyroid model using the 3Ds Max software. The model was then 3D printed with a Pursa i3 printer using the polycarbonate material. The Scintigraphy images were obtained after injection of Tc-99

The quality of the images in nuclear medicine was evaluated, where the images are similar to the images of a healthy human thyroid. The 3D printing technology shortens the time of phantom fabrication, and it shows good results to mimic the real geometry of the human thyroid.
