Computed tomography backprojection algorithm

What are CT reconstruction algorithms?
Image reconstruction in CT is a mathematical process that generates tomographic images from X-ray projection data acquired at many different angles around the patient.
Image reconstruction has fundamental impacts on image quality and therefore on radiation dose..
What is the advantage of filtered back projection?
Filtered back projection is an analytic reconstruction algorithm designed to overcome the limitations of conventional back projection; it applies a convolution filter to remove blurring.
It was, up until recently the primary method in cross-sectional imaging reconstruction..
What is the back projection algorithm for computed tomography?
The algorithm for back-projection is just a variation of that for rotating a Cartesian array.
Each projection is back-projected onto the object plane.
This plane is then rotated through the appropriate angle and the next projection back-projected.
The results are added together and the process repeated..

A universal back-projection formula is presented for three types of imaging geometries: planar, spherical, and cylindrical surfaces.
A solid-angle weighting factor is introduced in the back-projection formula to compensate for the variations of detection views._{Jan 19, 2005}

Back projection algorithm The name back-projection comes from the fact that a one-dimensional projection needs to be filtered by a one-dimensional Radon kernel (back-projected) in order to obtain a two-dimensional signal.

The Filtered BackProjection (FBP) algorithm is the basis for image reconstruction (converting from the measured data to the image) on modern CT scanners. FBP is a fast and direct method to generate CT images.

Parameter-free superresolution algorithm

SAMV is a parameter-free superresolution algorithm for the linear inverse problem in spectral estimation, direction-of-arrival (DOA) estimation and tomographic reconstruction with applications in signal processing, medical imaging and remote sensing.
The name was coined in 2013 to emphasize its basis on the asymptotically minimum variance (AMV) criterion.
It is a powerful tool for the recovery of both the amplitude and frequency characteristics of multiple highly correlated sources in challenging environments.
Applications include synthetic-aperture radar, computed tomography scan, and magnetic resonance imaging (MRI).
