Export Data from Matlab to Text Files

Hello

Working on a segmentation of 3D CT images.

I want to know Please

• what's the best software for 3D visualization for these images
• How to save these images (3D matrix 1536x1536x1101) into a file .txt

Does this code is the best to save it

if true
fid=fopen('data.txt','wt');
fprintf(fid,'%d %d %d\n',Matrix3D);
fclose(fid);
end

Please if you have any idea let me know.

Thank you

...these images (3D matrix 1536x1536x1101) into a file .txt

Why would you even think of saving image files as text? Use an appropriate image format or if staying in Matlab maybe a .mat or even stream via fwrite but NOT ASCII.

Thankx for you comment. In fact I would to save these images files as text to use it in 3D visualization .

One usual format for medical images such as yours is DICOM. You can try and use the matlab functions for DICOM editing/storage etc. and then you might want to use Osirix for viewing or other 3D features. Fx segmentation...

Probably you got the CT data from DICOM? or what format was that?

Also check the programme ITK-Snap

Thankx for your reply. I get CT data (.ISQ) from an external hard drive.
