| Outline of Final Research Achievements |
Pretreatment patient-specific quality assurance for radiotherapy is performed by measurement using simple rectangular or cylindrical phantoms; thus, the dosimetric errors caused by complex patient-specific anatomy are absent in the evaluation objects. In this study, we constructed a system for generating patient-specific three-dimensional (3D)-printed phantoms based on the patient computed tomography data sets. The results of this study demonstrated the feasibility of the 3D-printed phantom for artificial in-vivo dosimetry in radiotherapy quality assurance. This developed method will be the remarkable progress of the advanced dosimetry in radiotherapy and contribute to establishment and promotion of the precision and personalized radiotherapy treatment.
