Detailed Description

Forward project an image.

Author

Kris Thielemans

Usage:

forward_project output-filename image_to_forward_project template_proj_data_file [forwardprojector-parfile ]\n"

The template_proj_data_file will be used to get the scanner, mashing, ring difference etc. details, including energy information (its data will not be used, nor will it be overwritten). Time frame information is copied from the image.

Output is currently always in STIR-Interfile format.

The default projector uses the ray-tracing matrix.

Example parameter file for specifying the forward projector

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