regbfbp 0.5.1 © 2003-2013 by Turku PET Centre
Estimate the binding potential (BP) from simplified reference tissue
model [1]. The model is solved using the basis function approach [2],
similar to the RPM program for producing BP images.
Parameters:
1) Tissue TAC file (must be corrected for radioactive decay)
2) Name of reference region in tissue file, or name of file
containing reference tissue TAC
3) Isotope (C-11, F-18, ...)
4) Result file (existing file is overwritten)
Tissue TAC file must contain weights.
Options:
-min=<value (1/min)>
Set minimum value for theta3; it must be >= k2min/(1+BPmax)+lambda.
Default is 0.01 min-1. Lambda for F-18 is 0.0063 and for C-11 0.034.
-max=<value (1/min)>
Set maximum value for theta3; it must be <= k2max+lambda.
Default is 0.60 min-1.
-nr=<value>
Set number of basis functions; default is 5000.
-bf=<filename>
Basis functions are written in specified DFT file.
-E=<Fit end time (min)>
Use data from 0 to end time; by default, model is fitted to all frames.
-DVR
Instead of BP, program saves the DVR (=BP+1) values.
-svg=<Filename>
Plots of original and fitted TACs are written in specified file in
Scalable Vector Graphics (SVG) 1.1 format; specification in
http://www.w3.org/TR/SVG/
-fit=<Filename>
Fitted regional TACs are written in specified file.
