To address this limitation, an ensemble deep learning model was developed to automatically segment cochlear micro-anatomy from standard clinical scans. The model was trained and validated using an independent internal dataset comprised of paired synchrotron and clinical scans of the same cochlea across various acquisition protocols. Performance was evaluated quantitatively on an unseen internal test dataset and a multi-institutional external test dataset. The deep learning model achieved accurate segmentation of intracochlear anatomy across all tested modalities, outperformed all previously published models, and demonstrated strong viability on the multi-institutional external dataset. Furthermore, anatomical measurements on the automatic segmentations closely matched those obtained from high-resolution ground truth segmentations, confirming reliable estimation of clinically relevant metrics. By bridging the gap between high-resolution imaging and routine clinical imaging, this work provides a practical solution for patient-specific cochlear implant surgical planning and postoperative assessment, advancing the goals of atraumatic insertions and more effective hearing restoration.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='physics.med-ph'/>\n    <published>2026-03-25T16:17:00Z</published>\n    <arxiv:comment>29 pages, 6 figures, 2 tables, 3 supplementary figures, 1 supplementary table</arxiv:comment>\n    <arxiv:primary_category term='physics.med-ph'/>\n    <author>\n      <name>Ashley Micuda</name>\n    </author>\n    <author>\n      <name>Daniel Newsted</name>\n    </author>\n    <author>\n      <name>Nastaran Shakourifar</name>\n    </author>\n    <author>\n      <name>Sachin Pandey</name>\n    </author>\n    <author>\n      <name>Asma Alahmadi</name>\n    </author>\n    <author>\n      <name>Kevin D.
