Construct 3D visualization to calculate radius of curvature from OCT Scans

Hello,

I have an image sequence of OCT cornea slices, taken by imaging an eye by moving from left to right. I want to take each image, which is a slice of the cornea, and attach them together to make a 3D rendering of the cornea. From here, I can fit this 3D rendering into a sphere so I can calculate the radius of curvature of the cornea. I was hoping to use MatLab to do this. Does anyone know how to approach this?

I've attached a few of the frames from our images below---in total, we have around 1000 frames to create the rendering with.

Thank you so much in advance!

You'll need some spatial information - pixel and slice spacing. Do you have that info? Is the original data set a dicom or nifti or is it bmps?

[Sannath]

The original data is in bmps---as for slice spacing, we're not exactly sure what scale the OCT was imaging at, but I have some scans that we know the diameter of that I can use to set a scaling factor.

Hi Sannath,

I understand that you wish to make a 3D image from the 2D images you have.

Please follow the below link to know about how to convert 2D images into 3D model:

I hope the above shared resource will be helpful to you.

Sincerely,
