Figure 3From: 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 patientsReproducibility of CBCT images. CBCT images of the heart from one representative patient show overlap of the anatomical region. The reproducibility of the heart between the first CBCT (red line) and other images (blue line) are shown on the sectional and coronal planes.Back to article page
