Summary
[edit]DescriptionRadon transform sinogram.gif |
English: An intuitive visual interpretation of a sinogram obtained by a Radon transform or tomography.
For each orientation, the tomographic projections of the shape are shown in the middle bar: each vertical position is the accumulated signal from a horizontal slice through the shape. As the shape rotates, multiple such slices are taken, generating a sinogram on the right. The colors reveal what is going on: when the green line is aligned with the projection, all of its intensity gets concentrated so we obtain a bright green dot. The blue and red squares swap sides, and have either constant (aligned projection) or varying (diagonal projection) intensities. |
