Table 1 Differences of Dmean for the heart, pericardium and left ventricular myocardium after specific 3DCT image reconstruction and after accumulation

From: Comparison of the dose on specific 3DCT images and the accumulated dose for cardiac structures in esophageal tumors radiotherapy: whether specific 3DCT images can be used for dose assessment?
