Abstract：Objective To explore the feasibility of U-net-based AccuContour (AC) software in the automatic segmentation of clinical
target volume (CTV) and organs at risks (OARs) in breast cancer. Methods A total of 60 cases of early breast cancer after breast
conserving surgery were selected. The CTV and OAR swere manually delineated by physician. Of them, 40 patients were randomly
selected as the training set and the remaining 20 patients as the test set. Deep learning was carried out on the training set to set up
an automatic segmentation mode (Model-ST). The sketching results were analyzed by using the dice similarity coefficient (DSC),
Hausdorff distance (HD) and relative volume difference (RVD), and compared with the Model-AC provided by AC software.
Results The DSC value of CTV in Model-ST was better than that of Model-AC (P<0.05). In the automatic segmentation comparison
of OARs, the DSC values of bilateral lung, liver and esophagus of Model-AC were higher than those of Model-ST, the HD value
of bilateral lungs and the RVD value of left lung, trachea and esophagus were lower than those of Model-ST, the HD and RVD
value of heart is higher than Model-ST (P<0.05). Conclusion Compared with Model-AC, the Model-ST can achieve the automatic
segmentation of CTV in breast cancer accurately, while the original Model-AC of AC software has better accuracy in automatic
segmentation of OARs.
