The notion of a linogram is introduced. It corresponds to the notion of a sinogram in the conventional representation of projection data in image reconstruction. In the sinogram, points which correspond to rays which go through a fixed point in the cross section to be reconstructed all fall on a sinusoidal curve. In the linogram, however, these points fall on a straight line. Thus, backprojection corresponds to integration along straight lines in the linogram. A theorem is proved expressing the…

A theorem is described which expresses the back projection operator in terms of the Radon transform and simple changes of variables and a novel image reconstruction method based on the theorem is introduced.

Image reconstruction from linograms: implementation and evaluation.

It is demonstrated that the performance of the algorithm is superior to that of the filter back projection method in computational speed on realistic size problems and is equivalent to filtered backprojection in accuracy of reconstruction.

3D-reconstruction using cone-beam backprojection, the Radon transform and linogram techniques

The paper investigates the application of the linogram technique to an exact cone-beam filtered-backprojection algorithm and demonstrates the image improvement allowed by the use of linograms, as well as an important speed-up of the reconstruction.

A dual approach to linogram imaging for MRI

An alternate scheme for linogram image reconstruction, which is more logical from the viewpoint of its applicability to MRI data, is presented here and corresponds directly with the geometry of linogram data collected for MRI, in contrast to the LM reconstruction.
