How do I reconstruct a DICOM image and then re-slice it along a different axis?

Hey,

So I have a CT Scan consisting of 2D Images, and I was wondering if there was a way to reconstruct the 3D image and slice along the image in a different axis (that I define) using the data.

Anyone got any ideas?

Thank you, Bryan

Hello Bryan,

I am interested to hear if you found a solution. I am working on a similar problem. Here's a problem I see: When you take a slice along a new axis, there will be data that is missed (for example if you slice through the x-axis, you will miss data between CT images). As far as I know, you can't interpolate the data and so you would have incomplete slices. Please let me know if I am wrong though.

It sounds like these would form a nice 3-d matrix. Is it easy to align all these slices? If it is, then you can use the slice command to look through the 3-d matrix in any number of ways.

1. How do I process a Sequence of Files?
2. Use the above steps to insert each image into the corresponding slice of a three-dimensional image, e.g:

for ii = 1:20
  X(:,:,ii) = imread(['image',num2str(ii),'.jpg']);
end

1. 3! Now use any number of volume visualizing tools. A good place to start might be: slice-o-matic

y cómo se representarían?
