Comparison of patient setup accuracy for optical surface-guided and  X-ray-guided imaging with respect to the impact on intracranial stereotactic radiotherapy

ConclusionIn order to achieve the necessary geometric accuracy in cranial stereotactic radiotherapy, use of an X ‑ray-based IGRT system, especially when treating with non-coplanar couch angles, is highly recommended.
