Systematic errors in lung stereotactic body radiation therapy (SBRT): a caution on mixing and matching target delineation methods and planning CTs

Conclusions Depending on the reference images used, the COMs of the PTVFBCT, PTVBHCT, and PTV4D-CT are inconsistent, exhibiting significant shifts relative to each other. To avoid possible systematic localization errors, we recommend using 4D-CT/MIP for target delineation and AIP-CT for planning and alignment.
