Mean intercept length morphology measure anyone?

[Nic Roberts]

Hi,

Anybody done any coding of the Mean Intercept Length (MIL) morphological measure? I am working with trabecular bone and am looking for some code that I can use on CT images (that's the easy part) when exported from the CT machine.

Any help much apprieceiated. I have read the relevant papers by Hilliard et al

Dear Nic
Have you found the related code? I'm now in the same point! and in need of such a code to obtain Degree of Anisotropy for a trabecular bone...

I'm waiting eagerly for your response..

Hi Mo,

I didnt find any Matlab code for this. I did write some code to calculate the Star Volume Orientation then output the fabric tensor for a cube of trabecular bone if that would be any help to you?

Hi Nic, hi Mo,

I am also studying trabecular bone modeling on MatLab. I am looking for a way to code the importance of the MIL into my 3D model.
I am highly interested in your code, Nic if you are willing to share.

Thanks a lot,
Sasha

Hi Nic and Mo,

I am also looking to get the eigenvalues and eigenvectors from MIL using MATLAB. Did any of you end up completing your code or find one that could do this?

Sincerely,

Hello,

I have been doing some research about MIL direction calculation and I saw this post. I don't know if the problem is solved or not yet. I have been involved in research with CT data and I am using a commercial software which calculates MILs. However, the algorithm of the software is doing spatial research on 3D image (by changing phi and theta at each step) and calculates MIL for every step that you described.

I don't know what you specifically want to calculate with MIL directions. For instance, anisotropy calculation mostly depends on principle MIL direction is calculated by choosing the most condence part of your object the principle MIL is selected in between the search I mentioned. Anisotropy on the direction is calcuted as black-white distribution where the principle mean intercept pass through the object.

By choosing the length of the MIL, as I understand the software fits an ellipsoid by covering all objects inside your region of interest.

I hope this information will be helpful.

Hello. I need to find MIL tensor from a 2D image. Could you please tell me which commercial software you used?
