Abstract:
Intrafraction change in tumor position (Δ) was evaluated for stereotactic lung radiotherapy delivered with flattening filter free volumetric modulated arc therapy. In 140 fractions from 32 patients mean Δ (±SD) was -0.7±1.4 mm (vertical), -0.7±1.3 mm (longitudinal) and +0.2±1.2 mm (lateral) with mean vector 2.1±1.2 mm. Mean delivery time was 4.4±3.4 min (mean beam-on 1.9±0.4 min).
