iradon(sinog::AbstractMatrix, xs[, ys[, algorithm::AbstractProjectionAlgorithm[, coo::AbstractCoordinates]]]; <keyword arguments>)

Compute the inverse Radon transform of sinog on the points given by the vectors xs and ys. If ys is omitted, the reconstruction is performed on the square with xs == ys. The default reconstruction algorithm is FBP. Please refer to the respective documentation for additional parameters.

iradon(sinog::AbstractMatrix[, geometry::AbstractGeometry[, params::AbstractParams[, algorithm::AbstractProjectionAlgorithm]]]; <keyword arguments>)

Compute the inverse Radon transform of sinog with explicit geometry. If the algorithm needs specific parameters, these can be passed with params. Additional parameters can be passed to the algorithm through keyword arguments. Please see the respective documentation for more details. The default algorithm is FBP.
