Computed tomography radon transform

  • How do you find the transform of Radon?

    The Radon transform is the projection of the image intensity along a radial line oriented at a specific angle.
    R = radon( I , theta ) returns the Radon transform for the angles specified by theta ..

  • What does the radon transform do?

    The Radon transform is useful in computed axial tomography (CAT scan), barcode scanners, electron microscopy of macromolecular assemblies like viruses and protein complexes, reflection seismology and in the solution of hyperbolic partial differential equations..

  • What is Radon transform in CT scan?

    The Radon transform offers a means of determining the total density of a certain function f along a given line l.
    This line l is determined by an angle θ from the x-axis and a distance t from the origin as described in equation (3.1)..

  • What is the application of Radon transform in image processing?

    The Radon transform is widely applicable to tomography, the creation of an image from the projection data associated with cross-sectional scans of an object.

    Maps f on the (x, y)-domain to Rf on the (α, s)-domain..

  • What is the basic principle of Radon transform?

    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 equal to the line integral of the function over that line..

  • What is the inverse Radon transform CT scan?

    The Radon Transform allows us to create “film images” of objects that are very similar to those actually occurring in x-rays or CT scans.
    The inverse problem allows us to convert Radon transforms back into attenuation coefficients using the inverse Radon transform–to reconstruct the body from a CT scan..

  • What is the purpose of the radon transform?

    The Radon transform is useful in computed axial tomography (CAT scan), barcode scanners, electron microscopy of macromolecular assemblies like viruses and protein complexes, reflection seismology and in the solution of hyperbolic partial differential equations..

  • What is the radon transform for CT scan?

    The Radon transform is an integral transform whose inverse is used to reconstruct images from medical CT scans.
    A technique for using Radon transforms to reconstruct a map of a planet's polar regions using a spacecraft in a polar orbit has also been devised (Roulston and Muhleman 1997)..

  • The Radon Transform and Medical Imaging emphasizes mathematical techniques and ideas arising across the spectrum of medical imaging modalities and explains important concepts concerning inversion, stability, incomplete data effects, the role of interior information, and other issues critical to all medical imaging
  • The Radon transform is closely related to a common computer vision operation known as the Hough transform.
    You can use the radon function to implement a form of the Hough transform used to detect straight lines.
In a CT (computerized tomography) scan, these slices are defined by multiple parallel X-ray beams that are perpendicular to the object. This idea is shown 
The Radon transform can represent the data obtained from tomographic scans, so the inverse of Radon transform can be used to reconstruct the original projection properties, which is useful in computed axial tomography, electron microscopy, reflection seismology, and in the solution of hyperbolic partial differential

The Mojette Transform is an application of discrete geometry.
More specifically, it is a discrete and exact version of the Radon transform, thus a projection operator.

Integral transform

In mathematics, the X-ray transform is an integral transform introduced by Fritz John in 1938 that is one of the cornerstones of modern integral geometry.
It is very closely related to the Radon transform, and coincides with it in two dimensions.
In higher dimensions, the X-ray transform of a function is defined by integrating over lines rather than over hyperplanes as in the Radon transform.
The X-ray transform derives its name from X-ray tomography because the X-ray transform of a function ƒ represents the attenuation data of a tomographic scan through an inhomogeneous medium whose density is represented by the function ƒ.
Inversion of the X-ray transform is therefore of practical importance because it allows one to reconstruct an unknown density ƒ from its known attenuation data.
