Dosimetric assessment of patient-specific breath-hold reproducibility on liver motion for SBRT planning.

CONCLUSIONS: Non-negligible intrafractional motion occurs in patients with poor breath-hold reproducibility. To identify this subgroup of patients, acquiring three CTs with active breath-hold during simulation is a feasible practical method.
