Dosimetry verification of radioactive seed implantation for malignant tumors assisted by 3D printing individual templates and CT guidance.
OBJECTIVE
We compared the dose distributions of postoperative plans with preoperative plans for 3D printing template-assisted radioactive seed implantations.


METHODS
A total of 14 patients with malignant tumors enrolled in the study. The dose parameters included D90, minimum peripheral dose, V100, V150, and V200. The statistical method was the paired t-test.


RESULTS
There was no significant difference in P values between the two groups for all parameters except for V100.


CONCLUSIONS
The 3D printing guide template can provide good accuracy for radioactive seed implantation.
