Sinogram
Now, you should be able to generate sinograms from volume slice. Generate two sinograms from two volume slices:
-
One sinogram from a simple test image. You can use for instance a white circle as I was doing in the last section.
-
One sinogram from a real CT reconstruction. You should cite the source of that image. The Cancer Imaging Archive even explains you how to do that.
-
Show both the volume slices and the sinograms. Explain to the reader what they are seeing. What is the radon transform? Can the radon transform be inverted?
-
Do the sinograms contain some kind of symmetry? What is the reason for that? Do we really need a 360° degree scan?
This section should not be longer than one page.
