dc.description.abstract | These days, 3D-printers are on the rise in various fields including radiation therapy. This preliminary study aimed to estimate the dose characteristics of 3D-printer materials that could be used as compensators or immobilizers in radiation treatment. The cubes with length of 5 cm and different densities of 50%, 75% and 100% were printed by using a 3D-printer. Planning CT scans of the cubes were performed by using a CT simulator (Brilliance CT, Philips Medical System, Netherlands). Dose distributions behind the cube were calculated after a 6 MV photon beam had passed through the cube. The dose responses for the 3D-printed cube, air and water were measured by using EBT3 film and a 2D array detector. When the results of air case were normalized to 100, the dose calculated by the TPS and the measured doses to 50% and 75% cube were of the 96 similar to 99. The measured and the calculated doses to water and to 100% of the cube were 82 similar to 84. The HU values for the 50%, 75% and 100% density cases were -910, -860 and -10, respectively. The dose characteristics of the 50% and the 75% products were similar to that of air while the 100% product seemed to be similar to that of water. This information will provide guidelines for making an immobilization tool that can play the role of a compensator and for making a real human phantom that can exactly describe the inside of the human body. This study was necessary for Poly Lactic Acid (PLA) based 3D-printer users who are planning to make something related to radiation therapy. | - |
