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
     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.
     Simulate the contribution of vascular radioactivity instead of
     correcting for it, calculating Cpet from Ct using equations above.
 -h, --help

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

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
