Dynamic hybrid-phase computed tomography simulation in lung stereotactic body radiotherapy: A feasibility study.

To assess the feasibility of dynamic hybrid-phase computed tomography (CT) simulation when patients undergo lung stereotactic body radiation therapy (SBRT). Eighteen non-small-cell lung-cancer patients were immobilised in a stereotactic body frame with abdominal compression. All underwent dynamic hybrid-phase CT scans that were compared with cone-beam CT (CBCT).
