Fig. 2From: Evaluation of acute esophageal radiation-induced damage using magnetic resonance imaging: a feasibility study in micea 3D reconstruction of the cone-beam CT illustrating the dose planning and the esophagus (an OCT probe with CT contrast was inserted into the esophagus to differentiate the organ from surrounding tissue). b This sagittal cone-beam CT image shows the esophagus with the inserted OCT probe that was filled with CT contrast. c and d CT images show the radiation fields on the sagittal, coronal and axial planes. The radiation dose was calculated using Monte Carlo simulationBack to article page
