ecatfbp - tpcclib 0.8.0 © 2023 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
Display usage information on standard output and exit.
-v, --version
Display version and compile information on standard output and exit.
-d[n], --debug[=n], --verbose[=n]
Set the level (n) of debugging messages and listings.
-q, --quiet
Suppress displaying normal results on standard output.
-s, --silent
Suppress displaying anything except errors.
