Abstract

Tumor movement reduces the dose coverage of the target and may cause irradiation of normal tissues surrounding the target, which may reduce the effectiveness of radiation therapy. In the treatment of tumors in the thorax and abdomen, the patient’s breathing causes significant anatomical changes during irradiation. Accurate dose distributions can be determined on phantoms that can simulate respiratory motion and the associated organ shape changes. This study aims to develop and produce a liver phantom that can simulate breathing with 3D printing technology and molded silicone material, taking into account these uncertainties in radiotherapy treatments and developing technology.
