- Abstract: Objective To compare and analyze the accuracies of two kinds of software (AccuContour and DeepViewer) in the auto-segmentation of organs-at-risk, thereby evaluating their applicability and superiority in the radiotherapy for different tumors. Methods A total of 60 patients with different cancer were selected from Hefei Cancer Hospital, Chinese Academy of Sciences, including nasopharyngeal cancer, lung cancer, breast cancer, and cervical cancer, each of 15 cases. The organs-at-risk in CT images were auto-segmented by a physicist using AccuContour software and DeepViewer software. Taking manual segmentation as the standard, the Dice similarity coefficient (DSC) and absolute volume difference (ΔV) were calculated and paired t test was also carried out for analyzing the differences in segmentation results obtained by different software. Results The overall DSC of the segmentation results obtained by Accucontour software and DeepViewer software were 0.90±0.11 and 0.87±0.14 (t=-5.029, P<0.05), and the overall ΔV were (13.23±18.77) and (29.89±45.27) cm3 (t=7.344, P<0.05). All the DSC of 20 organs-at-risk segmented by AccuContour was greater than 0.7, of which brain had the maximum DSC (0.99±0.00), and the right lens had the minimum DSC (0.71±0.11). The segmentation results obtained by DeepViewer showed that 18 out of 20 organs-at-risk had a DSC greater than or equal to 0.7, and that the maximum (0.98±0.00) and minimum (0.63±0.18) DSC was found in the lungs and the right femoris, respectively. The ΔV of the 13 organs segmented by AccuContour were all less than those segmented by DeepViewer. Conclusion Both two kinds of software achieve satisfactory segmentation results, and have preferable performance in the segmentation of larger organs rather than smaller organs. Moreover, AccuContour is superior to DeepViewer in segmentation performance.
