Figure 5From: 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 patientsMean heart DVH of CT and CBCT images. Relative dose-volume indices were calculated through the DVH and caves (red line for CT and blue line for CBCT) were obtained using MATLAB 2012a. The two caves are separated.Back to article page
