SC volume analysis workflow. (a) Pre- and post-operative magnetic resonance imaging (MRI) scans are overlaid (differences marked in blue and red). (b) Pre- and post-operative MRI scans after resizing and alignment. Segmentation of the vestibular system based on (c) pre- and (d) post-operative data. Volume rendering of the segmentation result based on (e) pre- and (f) post-operative data. (g) Overlay of (f) onto (e). (h) Manual removal of voxels outside the filling defect region. (i) Volume difference representing the filling defect after surgery (marked in blue). (j) Three-dimensional visualization based on surface rendering using direct volume rendering. The red architecture indicates the volume difference between preoperative and postoperative data and represents the filling defect after surgical plugging. This cartoon for the SC volume analysis workflow was illustrated by Adobe illustrator 2020 (https://www.adobe.com/).
