imgcbv 0.3.1 © 2004,2008 by Turku PET Centre
Subtraction of the contribution of vascular radioactivity from dynamic PET
image in ECAT format. Vascular volume fraction Vb can be given as a value
that is common to all image pixels, or as (smoothed) Vb image, calculated
from a [O-15]CO study.
Parameters:
1) Dynamic image file (corrected for decay)
2) Blood TAC file (times in minutes)
3) Vb value or Vb image file (fraction, not percentage)
4) Output image file
Options:
-h, --help
Print this message and exit
-N
Negative TAC values are preserved; by default those are set to 0
-P
Equation Ct=Cpet-Vb*Cb is applied; this is the default mode
-T
Equation Ct=(Cpet-Vb*Cb)/(1-Vb) is applied
-BL=<Output filename for blood TAC>
If datafile for blood TAC interpolated to PET frame times is needed
--version or --build
Print software build information and exit
--silent
Program works silently, printing only warnings and error messages
--verbose
Program prints lots of information about what it is doing.
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
