Abstract:Objective To test and evaluate the feasibility of the RAIC.OIS software in automatic delineation of the liver for patients with abdominal tumor. Methods The planning CT images of twenty patients with abdominal tumor enrolled from February to
November 2018 were studied retrospectively. The structure of liver was automatically delineated in the CT images by the RAIC. OIS software of LINKING MED for each patient. Then, comparison between the automatic and manual delineation were made.
The differences in volume, position, shape, and time using were assessed between the automatic and manual delineation by the differences in volume (ΔV%), deviation of centroid (DC), dice similarity coefficient (DSC), and delineation time. The accuracy and
efficiency of the automatic delineation software were quantitatively evaluated by Sensitivity index (SI), inclusiveness index (IncI) and Jaccard coefficient (JAC). Results The ΔV%, DSC and DC between the automatic and manual delineation were (2.16±3.59)%,
0.92±0.02, and (0.38±0.35) cm respectively. SI was (0.93±0.02), IncI was (0.91±0.03), JAC was (0.85±0.04), respectively. The time of automatic delineation and manual delineation were (4.4±0.4) s, (507±74)s respectively. Conclusion By using the RAIC.
OIS software for automatic delineation of liver for patients with abdominal tumor, it could achieve good delineation accuracy and time saving. Thus the radiotherapy working efficiency could be improved effectively by using the software.
