Detailed Description

A preliminary class to prepare files for iterative reconstruction.

The intention of this class is to read measured data (and some processed data) and construct from these the projection data that are used in ML/MAP estimates, i.e.

  • normalisation times attenuation file
  • additive terms
Parameter file format
Prepare projdata Parameters:=
; next defaults to using all segments
; maximum absolute segment number to process:= ...

;;;;;;;;; input, some is optional depending on what you ask for as output
prompts_projdata_filename:= ...
trues_projdata_filename:= ...
precorrected_projdata_filename:= ...
randoms_projdata_filename:= ...

time frame definition filename:= ...
time frame number:= ...
; normalisation (should contain attenuation as well)
Bin Normalisation type:= ...

; if (prompts+randoms or trues) and precorrected data are given
;   construct scatter term by subtraction and write to file
; else if following is set, use it for scatter term
; else scatter term will be set to 0
scatter_projdata_filename:= ...

;;;;;;;; output files

normatten_projdata_filename:= ...

Shifted_Poisson_numerator_projdata_filename:= ...
Shifted_Poisson_denominator_projdata_filename:= ...
; name for additive term in denominator of a prompts reconstruction
