Need help with Cochlea's anatomy parameters calculation

I am new to 3D Slicer and still learning how to use this amazing software. I need your guidance and help for a very important reason.

My son has severe to profound hearing loss, and we have completed both CT and MRI scans. Now we are trying to **measure key anatomical parameters of his cochlea, such as:

  • Cochlear duct length
  • Modiolus-to-lateral wall distance
  • Basal turn diameter, and other relevant measurements

These measurements will help us (in consultation with our ENT surgeon) select the most appropriate cochlear implant electrode array for him.

Since I’m not yet familiar with how to do this accurately in 3D Slicer, I would be really grateful if someone experienced could either:

  1. Guide me step-by-step, or
  2. Help with the measurements. if I share the CT/MRI DICOM files (I can provide the report CD)

Please also let me know if there would be any charges for your time and effort—I am more than willing to compensate fairly.

Thank you from the bottom of my heart.

Warm regards,
Mukesh

@nagy.attila you have a lot of experience with this part of the anatomy. Could you help here? (I know you just started your vacation :slight_smile: Just asking now not to forget later)
