Subtract the contribution of vascular radioactivity with this tool. dftcbv can subtract the contribution of vascular radioactivity from regional PET TACs.
Vascular volume fraction Vb can be given as a value that is common to all regions, or as regional values in a DFT file, calculated from a [O-15]CO study.
Vb values that are >=1.0 are assumed to be percentages. Blood TAC can be given in a separate file, or as a region name inside regional TAC file.

Usage: dftcbv <Regional TAC file> <Blood TAC> <Vb> <Output TAC file>

Options:
-n
Negative TAC values 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.
