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.
