imgcbv - tpcclib 0.8.0 © 2023 by Turku PET Centre
Subtracts the contribution of vascular radioactivity from dynamic PET
image. Vascular volume fraction Vb can be given as a value that is common
to all image voxels, or as separate value for each image voxel in a
(preferably smoothed) Vb image, usually calculated from a [O-15]CO study.
Vb must be given as a volume fraction, not percentage, whether it is given
directly or inside the Vb image.
Usage: imgcbv [Options] imgfile btacfile Vb outputfile
Options:
-noneg
Negative voxel values are set to 0.
-pv | -tv
Equation Ct=Cpet-Vb*Cb is applied by default or with option -pv;
with option -tv equation Ct=(Cpet-Vb*Cb)/(1-Vb) is applied.
-sim
Simulate the contribution of vascular radioactivity instead of
correcting for it, calculating Cpet from Ct using equations above.
-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.
Example 1: Vascular volume fraction in all tissue is assumed to be 0.04:
imgcbv ua2918dy1.img ua2918ab.kbq 0.04 ua2918cbv.img
Example 2: Vascular volume fraction is given in specific image file:
imgcbv ua2918dy1.v ua2918ab.kbq ua2918vb.v ua2918cbv.v
