DOSIMETRIC CHARACTERISTICS OF 3D PRINTED MATERIALS

Radiotherapy is one of the most applicable techniques for the treatment of cancer patients. High accuracy and precision is required in the whole treatment chain from the dose assignment to the final implementation. Patient's individual anatomic conditions and radiobiological sensitivity are influencing tissue response to irradiation, since radiation induced late toxicities of III-IV grade have a noticeable impact for a patient further quality of life. To assure the highest treatment quality, it is recommended to combine at least few individualized patient's dosimetry methods [1-3]. Exploring the latest technological achievements, application of 3D-printed organ models of varying size and shape fabricated from materials of different densities has been suggested for an individual dosimetry. This paper provides a short overview over the different materials used for 3D printing, their dosimetric characteristics and also printing techniques that are applicable in the individualized patient's dosimetry in radiotherapy.
