Detailed Description

Back project an image.

Author

Kris Thielemans

Usage:

back_project output-filename image_to_back_project template_proj_data_file [backprojector-parfile ]\n"

The template_proj_data_file will be used to get the scanner, mashing etc. details (its data will not be used, nor will it be overwritten).

The default projector uses the ray-tracing matrix.

Example parameter file for specifying the back projector

Back Projector parameters:=
  type := Matrix
    Back projector Using Matrix Parameters :=
      Matrix type := Ray Tracing
       Ray tracing matrix parameters :=
       End Ray tracing matrix parameters :=
      End Back Projector Using Matrix Parameters :=
End:=
