CAT Scanning
Here are some sample images that illustrate the process. The algorithm is quite simple.
In a real CAT Scan system the 1 dimensional slices would be taken from the horizontal row of a series of x-rays. In this demo I don't yet have the x-rays to work with so I synthesize the 1D bands from the target image that I want to regenerate. So given a target image I generate a series of 1D radial slices by rotating the target image and then averaging all values in the rows of the image. Then I rotate the slice back to the original angle.
Slices are synthesized from a 180 degree rotation of the target image.
The target and four 1 dimensional sections. The position of the sections corresponds to the angle of projection. | Cell 3 | Cell 4 |
