Automatic detection of veterbrae regions.

I would like to detect automatically the vertebral body in a MRI image (DICOM). To know the centroid's coordinates.To detect veterbrae and location. To detect the centers of disks. Finally evaluate the space between the disk and the veterbrae.

Please I need responses.Thank you so much.

Thanks Ashvin you are very helpful.I am still reviewing and see how I can apply it to my work.

If you upload one of your images (to tinypic.com, for example) for us to view, we would be able to give more specific advice.

For your purposes, I would do the following:

dcm = dicomread('/path/to/an/image.dcm');   %read in DICOM
imshow(dcm, []);    %display DICOM
colormap jet;       %switch to colored display, so that is renders more clearly in jpeg
im = getframe(gcf);  
imwrite(im.cdata, 'sampleimg.jpg');  %write out jpeg

And then upload sampleimg.jpg to tinypic.com, and link to it in your question.

Thanks Matt, but this is my question; I would like to detect automatically the vertebral body in a MRI image (DICOM). To know the centroid's coordinates.To detect veterbrae and location. To detect the centers of disks. Finally evaluate the space between the disk and the veterbrae.

Thanks once again

Yes, I get what you are trying to do. But to do this, you need to be able to segment out the vertebral body, which means that we need to have a sample image for reference. Please, help us help you.
