Evaluating the Therapeutic Dose Distribution of Intensity-Modulated Radiation Therapy for Head and Neck with Cone-Beam Computed Tomography Image: A Methodological Study

<table>The isodose line (left), gamma (2%, 2 mm) comparison (right) on the transversal plane, and DVH changes for the simulation condition with a −3 mm positioning deviation along the A-P direction. The upper row is the result of correct positioning and the second row is the result with positioning deviation.</table>
