Abstract：Objective To explore and evaluate the application value of AccuContour in automatic oral delineation in patient with
oromaxillofacial head and neck tumors radiotherapy. Methods Thirty patients with oromaxillofacial head and neck cancer treated
in our hospital from May to September 2020 were selected. The oral structure in CT images was manually and automatically by
AccuContour. The accuracy of the software was evaluated using dice similarity coefficient (DSC), volume difference percentage,
centroid distance gap, and hausdorff distance. Results The DSC of oral cavity was 0.76±0.1 and the volume difference ratio was
-49.43%~63.78%. In the difference of centroid distance, the difference between y (up and down) direction and z (front and back)
direction was greater than x (left and right) direction, the differences of three directions were (-0.02±0.09) cm, (-0.28±0.26) cm and
(-0.31±0.55) cm, respectively. The Hausdorff distance was (1.96±0.56) cm. The DSC has a correlation with the volume difference
ratio (P<0.05) and has a linear correlation. Conclusion AccuContour has a good application effect in the automatic delineation of
oral structure in patients with oromaxillofacial head and neck tumor radiotherapy. But there is still a deficiency in the delineation of
CT positioning image affected by metal artifacts, which requires further manual modification.
