ecatfbp - tpcclib 0.7.5 © 2020 by Turku PET Centre

Reconstruct PET image from attenuation and normalization corrected
2D PET sinogram using filtered back-projection (FBP).
This program does not correct image data for decay.
Image is corrected for the dead-time based on factors in the sinogram.
Image data is written in units ECAT counts per pixel per second.
 
Not for clinical use! Program is not thoroughly tested!
 
Usage: ecatfbp [Options] scnfile imgfile
 
Options:
 -filter=<None|Ramp|Butter|Hann|Hamm|Parzen|Shepp>
     Set the reconstruction filter; by default Hann.
 -cutoff=<value>
     Set cut-off value; by default 0.3.
 -zoom=<value>
     Set zoom factor; by default 1.0 (no zoom).
 -dim=<value>
     Set image x and y dimensions; by default 128.
 -rot[ation]=<value>
     Set image rotation in degrees, -180 - 180; by default 0 (no rotation).
 -x=<value>
     Set image shift in x direction (in cm); by default 0.
 -y=<value>
     Set image shift in y direction (in cm); by default 0.
 -perv
     Divide image voxel values by voxel volume (mL); by default the voxel
     volume is corrected later during image calibration.
 -h, --help

 -d[n], --debug[=n], --verbose[=n]
     Set the level (n) of debugging messages and listings.
 -q, --quiet
