Image Processing Toolbox Release Notes Previous page   Next Page

Fan Beam Projection Transforms

The toolbox includes two new functions, fanbeam and ifanbeam, for computing an alternative mathematical representation of an image using fan beam projections. Using the ifanbeam function, you can reconstruct an image from fan beam projection data.

The toolbox also includes functions, fan2para and para2fan, for converting projection data between fan-beam and parallel-beam geometries. (You use the radon function to create parallel beam projection data.)
