Abstract Details

2017, Master of Science, Ohio State University, Electrical and Computer Engineering.
In this research, we proposed an atlas-based automated segmentation approach which used 6 manually traced CT volumes (including the reference CT volume) to construct the atlas. We then registered the test CT volumes to a single reference volume. A series of morphological processes were implemented to segment the temporal bone anatomy. A 3D-view based tracing tool `VolEditor’ was used to provide the manual tracing results of the test data to compare with our automatic segmentations. The validation results of our method on 20 test clinical CT volumes (10 left, 10 right) resulted in average DICE similarity coefficients over 0.6 for cochlea, malleus and incus and ranged from 0.46 to 0.64 for facial nerve, semi-circular canals and vestibule. The proposed method didn’t reach the precision required for surgical planning but was effective for segmenting structures required in surgical simulation software. Additionally, we determined that the 3D manual tracing tool, used in this study, resulted in segmentation errors that caused degradation of the validation results.
