Radiobiological evaluation considering setup error on single-isocenter irradiation in stereotactic radiosurgery

CONCLUSION: The TCP in SRS for multiple brain metastases with a single-isocenter technique may decrease with increasing isocenter distance and decreasing GTV size when the 6DoF setup errors are exceeded (1.0 mm, 1.0°). Additionally, it might be possible to better maintain TCP for GTVs with 6DoF setup errors by using the optimal isocenter position.PMID:34151498 | DOI:10.1002/acm2.13322
