Fully Automated Delineation of Gross Tumor Volume for Head and Neck Cancer on PET-CT Using Deep Learning: A Dual-Center Study

<div>Comparisons between GTVm and GTVa. GTVm, the gross tumor volume by manual delineation (gold standard). GTVa, the gross tumor volume of automatic segmentation by the proposed method. Each point represents a patient. DSC, dice similarity coefficient. (a) Difference between GTVm and GTVa. Sensitivity (b), precision (c), and DSC (d) of GTVa (the average values are depicted as a thick dashed line).</div>
