Radon Transform -- from Wolfram MathWorld
The Radon transform data is often called a sinogram because the Radon transform of an off-center point source is a sinusoid. Consequently, the Radon transform of a number of small objects appears graphically as a number of blurred sine waves with different amplitudes and phases. See more In mathematics, the Radon transform is the integral transform which takes a function f defined on the plane to a function Rf defined on the (two-dimensional) space of lines in the plane, whose value at a particular line is … See more If a function$${\displaystyle f}$$ represents an unknown density, then the Radon transform represents the projection data obtained as the output of a tomographic scan. Hence the inverse of the Radon transform can be used to reconstruct the … See more • Periodogram • Matched filter • Deconvolution See more • Weisstein, Eric W. "Radon Transform".

See more In algebraic geometry, a Radon transform (also known as the Brylinski–Radon transform) is constructed as follows.
