Figure 2From: The feasibility of evaluating radiation dose to the heart by integrating kilovoltage-cone beam computed tomography in stereotactic body radiotherapy of early non-small-cell lung cancer patientsHeart reproducibility in 40 series. The fifth layer shows the worst reproducibility, which reaches more than 0.98. The coinciding heart regions on the same anatomical section between the first series of CBCT images and other images reached up to 0.985 ± 0.020 from the first to the 40th section.Back to article page
