Abstract：Objective To compare the accuracy of three kinds of automatic delineation software (Pinnacle 9.10, Linkingmed and
Manteia) in delineating upper abdominal organs at risks (OARs). Methods The OARs (liver, spinal cord, kidneys, pancreas and
stomach) was manually drawn by a senior clinician in 26 patients with upper abdominal tumors, and three kinds of software were
used to automatically draw the OARs. By the standard of the manual delineation, the index of center of mass deviation (DC), dice
similarity coefficient (DSC), Hausdorff distance (HD), inclusive index (IncI) and sensitivity index (SI) were compared for three kinds
of segmentation results. One-way analysis of variance was used to evaluate the statistical difference of each index, and the accuracy
of the three software was compared. Results There were significant differences in DC, DSC, HD, IncI and SI of the liver, kidneys
and spinal cord between the Lingkingmed and Manteia, groups with the pinnacle group (P<0.05). The automatic delineation results in
Lingkingmed and Manteia were both better than those in Pinnacle. For the results of stomach and pancreas, Manteia group was better
than Lingkingmed group, there were signficantly differences (P<0.05) in Lingkingmed and Manteia, except for IncI. Conclusion All
three softwares of auto-segmentation can satisfactorily contour the liver, kidneys and spinal cord. The performance in Lingkingmed
and Manteia was better than Pinnacle, and Manteia was better than Lingkingmed in the delineation of stomach and pancreas.
