| Abstract:: |
| Objective To investigate the accuracy and errors of 3D printing individual non-coplanar template (3D printing template) for 125I seed implantation in head and neck, thoracic and pelvic recurrent carcinoma.Methods From 2015 to 2016, a total of 41 patients treated with 125I seed implantation under 3D printing template were analyzed. All of them were conducted with CT-simulator scan two days before operation. The x and y axis position errors of 3D printing template between pre- and intro-operation plan, and set-up error in different site and position were analyzed. Results The x and y axis 3D individual non-coplanar template set-up position errors in head and neck, thoracic and pelvic location were (1.77±1.09), (2.66±1.65), (4.00±1.41), (5.22±1.85), (1.88±1.29) and (2.52±1.37) mm, respectively. Compared with thoracic, statistically significant difference was found in the head and neck and pelvic in x and y axis position errors (t=-3.730, -3.080, -3.944, -4.519, P<0.05). No statistically significant difference was observed in other results (P<0.05). Conclusions 3D printing individual non-coplanar template assistant I-125 seed implantation are more accurate and efficiency. |
