Please tell me the best way to load .Raw ct image into MATLAB?

5 views (last 30 days)
What is the recommended approach for loading a CT scan image of a rock with dimensions of 1000x1000x1000 Unit8 in .raw format into MATLAB for image processing, particularly for those who are new to this field? Could someone please provide a comprehensive guide, starting from the basics, that can be easily followed by beginners? Your expert guidance on this matter would be greatly appreciated. Thank you.

Thank you for your reply. I highly appreciate that. I kind of converted it into tiff format using image J and loaded using imread, but please tell me What could be the possible reasons for getting an error message indicating that the order of an image loaded into MATLAB is 1000x1000 instead of the expected 1000x1000x1000 dimensions, despite the image having three dimensions? Are there any recommended approaches or functions to use when loading 3D images into MATLAB to avoid such errors?

Please share the code you are using and the full error message (all the red text).
If you have a 3D tiff image, I think you should be using tiffreadVolume instead of imread. It sounds like imread is only loading a single image and not the volume.

Use image(), imshow(), imagesc():
% To view Tiff image:
A = tiffreadVolume('TIFF_Image.tiff');
% image()
image(A(:,:,1)) % View Layer 1
% imshow()
imshow(A(:,:,2)) % View Layer 2
% imagesc()
imagesc(A(:,:,3)) % View Layer 3
