Background:

Cochlear implants (CIs) are crucial for restoring hearing.
Electrode array location in the cochlea correlates with hearing outcomes.
Current localization methods are model-specific or labor-intensive, hindering large-scale analysis.

Purpose of the Study:

To develop a general and automatic method for localizing cochlear implant electrode arrays in CT images.
To enable comprehensive analysis of electrode placement and its impact on hearing outcomes across diverse CI models.

Main Methods:

A novel graph-based algorithm for identifying optimal paths of fixed length was developed.
The method automatically localizes electrode arrays in CT scans.
The approach is designed to be general and effective for various cochlear implant models.

Main Results:

The proposed method achieves sub-voxel localization accuracy.
The technique demonstrated effectiveness across different cochlear implant models.
Localization is automatic and generalizable, suitable for large datasets.

Conclusions:

This automated, generalizable method overcomes limitations of previous techniques.
It facilitates large-scale research into electrode placement and hearing outcomes.
The findings could lead to improved cochlear implant designs and better hearing restoration for users.
