Abstract:

Purpose: Verified the delivered dose distribution of lung cancer Stereotactic Body Radiotherapy (SBRT) using the cone-beam CT images.
Methods: Five lung cancer patients underwent SBRT with 25 CBCT images were enrolled in this study. Delivered dose distributions were recalculated on CBCT images with deformed and nondeformed method, respectively. The planned and delivered dose distributions were compared using the dose-volume histograms.
Results: The delivered target coverage (V100) per patient inside target volume deviated on average were 0.83% ± 0.86% and 1.38% ±1.40% for Pct vs. Pcbct and Pct vs. Pdcbct, respectively. The Conformity Index (CI) and Gradient Index (GI) showed a good agreement among the plans. For the critical organs, only minor differences were observed between the planned dose and delivered dose.
